  1. Sadly, coffee is a perfect example of how too much of a good thing can go bad.
    Current guidelines for adults suggest 400 milligrams/day.
    That’s 3-5 cups per day.
    More than that can cause side effects such as restlessness, irritability, stomach problems, irregular heart beat and muscle tremors. Drinking coffee later in the day can cause insomnia.
    You can go down the rabbit hole and scare the heck out of yourself! Caffeine is a central nervous system stimulant, so thinking in the general realm of “jacked up’’ checks a lot of boxes.

  2. I will answer this question going from my own experience as opposed to in an educationally pretentious and patronising fashion! When I have drank too much coffee or caffeine I get a little jittery, I used to drink it throughout the day, a mix of black coffee and Redbull – that type of nonsense, I’d feel completely fine but later on in the day my heart felt somewhat out of sorts, as though it was pumping out of my chest… which actually sounds pretty horrific but knowing it was down to the caffeine I knew it was self-inflicted. The way I counteracted this pretty scary problem would be not to panic, drink lots of water as caffeine in any context is a diuretic as well as a stimulant so you get pretty dehydrated and obviously now I don’t drink as much coffee and I am more aware of my caffeine intake, however, this stimulant comes in all shapes and forms so I can’t say I’m ‘clean’. The moral of this spraff (story – sorry i’m a Scot!) is just listen to your body and be sensible.
    I am pretty certain you have read the horror stories about what too much caffeine can do to you, I hate to be one of those people to preach but coffee isn’t only the only source of caffeine, tea also contains this as do the obvious products like energy drinks (Redbull, Monster, Mountain Dew if you are in the US, I’m in the UK) I say this to reiterate how dangerous caffeine overload can be, completely by accident, I also had a pretty scary experience of overconsumption myself, I will not go into depth as these kinda elongated answers have me falling asleep by the time you get to the point (hence losing the readers attention span rapidly) but lets just say I am quite switched on to how important my heart is and how STUPID caffeine can be when used as an energy boost, I did it without realising, taking it little and probably too often but not really thinking too much about it then – BAM I was having a heart attack or so I thought and I wasn’t far off, just be aware of what you are putting into your body and listen to what it tells you, if you enjoy it, do so moderately but do not use it to stimulate yourself, there are plenty other ways to achieve this, trust me!! 🙂

  3. Hey, this sounds similar. Oh, I have been a victim of this as being a coffee addict.
    There are not much side effects
    Just sleep cycle is disturbed.
    You only feel a lot tired the whole day.
    You can mess up with your bp levels.
    You could also become a coffee addict. (hahahahah speaking from personal experience ).

  4. Caffeine is the world’s most widely consumed psychoactive drug. It is commonly found in tea, coffee, and cacao plants.
    Caffeine works by stimulating the central nervous system (CNS), heart, muscles, and the centers that control blood pressure. It can raise blood pressure, but might not have this effect on people who use it all the time.

    Side Effects of Caffeine
    However, ingesting caffeine☕in high doses may lead to more harmful effects on health. Several unwanted side effects of consuming more than 400 mg of it per day include:
    A fast heartbeat
    Agitation
    Restlessness
    Sleeping problems
    Tremors
    These effects can also present when people experience caffeine withdrawal.
    Hope you will find this informative☺

  5. More coffee means how much more ?
    2 cups per day is fine no health issues.
    Going beyond that is where addiction starts.
    Our body adapts to coffee. With time it needs more of it to get the benefits such as better mental clarity, more alertness, better focus, taste and so on.
    Now once you over do coffee, problems appears such as
    Insomnia
    Nervousness
    Anxious
    Moody
    Feeling Depressed
    Don’t over do it !

  6. Good question and one I am well familiar with.
    More than likely a sharp shift into the sympathetic branch of the autonomic nervous system, accompanied by the release of the stress hormones adrenaline, nor-adrenaline and cortisol. This is why we get the rush or high from a strong espresso, which if taken once during the day, can’t imagine this being too harmful for the majority of people, depending on your brand.
    Caffeine tablets and caffeine from energy drinks on the other hand are a different story, I imagine it’s much easier to overdose with these rather than coffee (however I have taken far too much coffee before and what I will share here is probably a good indicator of adrenal fatigue).
    A surplus of caffeine leaves you constantly in the sympathetic state (fight or flight) along with stress hormone release, blood sugar imbalances and the dreaded crash, your kidneys tend to take quite a beating, especially those little adrenal glands that sit on top of either kidney.
    The symptoms I experienced were slight nausea, anxiety, tiredness, fatigue, panicking and a general spacy feeling (totally ungrounded). It wasnt one of my finest moments.
    Moreover the coffee I used to drink was full of mould and toxins which further stressed the system and placed an extra burden on the Liver and Kidneys (not something you want to do too often).

  7. Caffiene can cause a negative feedback loop because it’s half life is approximately 5.8 hours.
    Individuals feel tired so they drink Caffiene. Which stays in the system for almost 24 hours, which disrupts sleep due to overstimulation of the sympathetic nervous system, they wake up tired and they repeat the vicious cycle all over again.
    That means drinking 200mg of caffiene at 6 will still have it in your system by 12 (with just 100mg).
    Caffiene also stresses the sympathetic nervous system by increases the release of adrenaline, the chemical responsible for the flight or fight response. This increased stimulus to stress could create anxiety, or increase agitation.
    Caffiene withdrawals work because the brain has built up a tolerance for Caffiene, mainly by blocking adenosine (the tired hormone) and by releasing other neurotransmitters to compensate for the Caffiene binding to other receptors in the brain. Once people stop taking Caffiene they begin to experience withdrawals, which have been shown to physically hurt.
    Caffiene also restricts the blood vessels. It’s used in a lot of medications and it’s also a good natural cure for a headache.
    Caffiene also slows down the absorption of insulin when one eats a high-carb meal. It also helps the muscles regain glycogen after workouts.
    Caffiene can decrease the perception of feeling tired and is used during athlete competition.
    Contrary to popular belief, Caffiene is just a stimulant, the most widely used psychoactive drug on the planet. It stimulates the nervous system and this in turn allows people to stay up a little later.
    Drinking excessive Caffiene before bed could decrease the total amount of REM sleep. REM sleep is important for vital repairs and memory consolidation via the hippocampus and temporal lobes.
    Fun fact: drinking Caffiene after studying has been shown to allow for better retention of information. This study was done on a group of college women.
    I’m sure Lila Ernst could tell you all about Caffiene withdrawal.

  10. When I have had too much coffee, I’ve had several negative effects, like being super jittery, jumpy, trembling, anxiety. I have even wondered if too much coffee has led to having those ‘visual migraines’ where there appear to be wavy fields in at least one eye…? But can’t say for sure. All I know is how I go from being very productive and getting lots done to trying not to look like I have a nervous disorder!

  13. Coffee is not the problem; it’s the caffeine in the coffee that causes the problems.
    When I was diagnosed with something called atrial fibrillation, I lucked out when they were able, after a year of my taking blood thinners (warfarin) to shock my heart back into its normal and lovely sinus rhythm.
    As I talked to my cardiologist afterwards, I asked what if anything I could do to prevent a recurrence. He advised that I end my normal practice of grinding full caffeine beans and running them through a French press every morning. Now, there is no easy answer to what causes or prevents one from getting a-fib, but I have taken his advice to heart and still grind my beans and have a healthy cup of coffee in the morning, but it is decaffeinated and my face no longer flushes and my heart no longer beats double time when I climb a flight of stairs.
    And you know what? A really good cup of decaf is still a really good cup of coffee. Whereas 97% of the caffeine is gone, 97% of the taste remains. That works for me.

For instance if you have a family history of heart disease, dementia or cataracts, caffeine may slightly increase your probability of illness. Fewer cups, decaf, organic, and the benefits of antioxidants in coffee may improve your immune likelihood.

  23. Many of the people I know in my age bracket (50+) have cut down or eliminated caffeine entirely because it creates anxiety or has some other undesirable mood effects. Caffeine’s effects can be subtle but easy to notice once you get off it. You might be a different person without caffeine in your system.
    For myself I went thru 3 weeks of serious withdrawals headaches and cravings when I quit cold turkey 8 years ago. That caffeine is a serious drug is usually unappreciated, probably because its use is so deeply embedded in all the world’s cultures.

    I know it makes you feel more alive and refreshed in the morning but they are nervous stimulants and can have a bad effect on nervous system

    Instead you can drink green tea that too in moderation most of it contains caffeine which is not good for the body
    I drank tea outside and it is loaded with artificial sugar which can cause pimples and other side effects
    I drank tea because I wanted to be awake at night,even green tea makes my sleep disappear if consumed at night

  26. Define “too much.” If I drink more than two or three cups of regular coffee at a sitting, my heart rate and blood pressure rise uncomfortably high and I have to go to the bathroom often. If you were crazy enough to drink, say, ten cups of coffee at a sitting, that effect would just multiply. And if you drank enough to overdose on caffeine, you would likely have a heart attack or stroke.

  27. I’ve only taken too much caffeine once. And it was from drinking 3 Rockstar energy drinks back to back to back.
    I had ZERO patience. Slightly shakey. Irritable. And, I got into a shouting match with my boss!
    Maybe it was the caffeine and sugar? All I remember is, two drinks was plenty for me. So, adding more caffeine to what was obviously my threshold made me blow my gasket.
    Although, milligram-wise, I drink way more caffeine now, then I did back then.

Too many sugary drinks can offset your sugar level and I drink my coffee with cream and 2 teaspoons of sugar. A small amount of caffeine can be beneficial, but not large amounts. I’m not sure that science or medicine have decided on the effects of coffee yet. I’ve read several conflicting articles lately.

    If Tea or Coffee consumes at the wrong time or excessive amount
    Tea and coffee can disturb your acid and alkaline balance on empty stomach.
    It can cause stomach irritation when consumed on empty stomach.
    It has tannins, Caffeine that can stimulate the acid production in your stomach and thus lead to an upset stomach, frequent urination.
    It can also hamper the nutrient absorption in the body.
    Tea and coffee can have in between meals. However, people who have a history of gut-related issues may still face discomfort like bloating, acidity, stomach pain even when it is consumed in between meals, Then it should be restricted.
    It depends upon your rate of caffeine metabolism as per your genes.

  35. I had pretty bad experience one day when i took about 5 grams of anhydrous caffeine. I was stimulated for a while and felt very awake and alert, then i was too stimulated to concentrate on any one thing at once and was not productive. I stated to feel mentally alert, yet physically exhausted at the same time.
    My heart and pulse started to race at a level that I was very concerned about (I could hear my own pulse), but was not quite yet a medical emergency.
    The most bizarre part of the experience was finding out that it is possible to urinate about 20 times per hour! I felt like I was peeing out water as fast as I could drink it. I drank about 8 liters of water that day after that.
    I wouldn’t reccomend caffeine at those levels to anyone! Calc 2 test or not!

  36. Coffee is everyone’s favourite beverage, drinking it every morning is healthy but getting addicted to this is not okay. Caffeine can have a destructive effect on your sleep cycle. It can make it difficult for you sleep.
    It can cause insomnia and restlessness in your body. Which can stress your mind too.
    Also, if you suddenly stop consuming coffe you can experience headaches,anxiety,fatigue and irritability.

    No additives whatsoever (no sugar, cream, milk, etc.).
    Balanced your consumption with enough water intake.
    Always eat before getting your coffee.
    Consume only good quality coffee beans.
    Consume only arabica.
    Properly roasted your beans (keep it at medium).
    Not drinking instant coffee whatsoever.
    However, drinking a lot of it will make you urinate often, that is why drinking a lot of water is a necessity. If you’re drinking a lot of coffee, to balance it with your meals is also a must, coffee is acidic, eating properly prevent digestive problems.
    If we measure it by cups (150 ml), my daily consumption is 3–5 cups/day, I have no problem.

    Image source: coffee could be a lifesaver [ https://www.askdrray.com/coffee-could-be-a-lifesaver/ ]
    1. Recently it has been shown in a large study that coffee, caffeinated or not is associated with lower overall mortality.
    2. Coffee has long been a subject of heated discussions. It has been praised or condemned. Many studies have been done in the past; some showed health benefits, some did not. A new, larger study [ http://circ.ahajournals.org/content/early/2015/11/10/CIRCULATIONAHA.115.017341.abstract?sid=f9171c51-1b1d-4d35-ac9c-9f3a793a7cb7 ] was done by the Department of Nutrition, Harvard School of Public Health in Boston, MA to re-examine this issue for both caffeinated and decaffeinated coffee.
    3. Mortality was determined among 74,890 women in the Nurses’ Health Study (NHS), 93,054 women in the NHS 2, and 40,557 men in the Health Professionals Follow-up Study after a medium follow-up of 22.5 years. 19,524 women and 12,432 men died during that time period. Ming Ding is a doctoral student in the Harvard School of Public Health department of nutrition and was the lead author of the study that was published in the medical journal “Circulation”. She pointed out that in the past there were confounding problems: although many studies had shown that both caffeinated and decaffeinated coffee consumption lowered the risk of cardiovascular disease, the results in many studies were blurred. Studies often did not distinguish between smokers and nonsmokers; so a beneficial effect from coffee drinking was wiped out by the cardiovascular risk from smoking.
    4. Ding’s studies took this into account and also other confounding factors like how much sugary soda pop people were drinking and whether or not they were eating well. In addition they normalized for other factors that could interfere like drinking alcohol and eating red meat. Without normalizing for the factors mentioned above the study results were as follows. Study participants had less than a cup of coffee and three cups a day had a 5% to 9% lower risk of dying than those who drank no coffee. Those who drank more than three cups a day did not see any benefit.
    5. However, when all the confounding factors were removed and the various groups were compared again the following emerged:

    * Less than 1 cup of coffee per day: 6% lower death rates than non-coffee drinkers.
    * 1 cup to 3 cups of coffee per day: 8% lower death rates.
    * 3 to 5 cups of coffee per day: 15% lower death rates.
    * More than 5 cups of coffee per day: 12% lower death rates.

    Ming Ding was associated with another research paper [ http://www.ncbi.nlm.nih.gov/pubmed/24459154 ] that had shown that coffee drinkers have a lower risk of developing type 2 diabetes and heart disease. She found that both caffeinated and decaffeinated coffee reduced the risk of getting diabetes later in life. When asked about what would be responsible for the reduced death rates with coffee consumption, Ding explained: “There are at least two known chemicals in coffee, namely lignans and chlorogenic acid that could reduce inflammation and help control blood sugar, both of which could help reduce the risk of heart disease”.
    Although there seems to be a linear response up to 5 cups of coffee consumption, above 5 cups this linear relationship disappeared. It was not explained whether there was a saturation point reached, whether there was yet another hidden confounding factor or whether there were detrimental effects on the adrenal glands with too much coffee consumption.
    Another finding was that it did not matter whether the coffee was regular (caffeinated) coffee or decaffeinated coffee. The results were identical.
    Many other studies did not have the large numbers to show whether or not decaffeinated coffee was as effective in preventing heart disease.
    6. Finally, there was another peculiar finding; suicides were down by 20% to 36%, if a person drank at least one cup of coffee per day. But if a person consumed less than 1 cup of coffee per day the suicide rate was 36% higher than the control group with no coffee consumption. This is a rather peculiar finding, particularly for the consumption of less than 1 cup of coffee. But other studies have also shown a decrease in suicide rates with coffee consumption.
    Although previous studies had shown a reduction in liver and prostate cancer, after the removal of confounding factors this study did not show any effects on cancer causation or cancer death rates with coffee consumption…

    In smaller amounts, it can make you twitchy and anxious. It can make it hard to get to sleep. Some people are a lot more sensitive to caffeine than others. I’ve been drinking strong coffee for decades and even I don’t drink coffee after about 8:00 PM.

  54. Honoré de Balzac was a French poet born in 1799 and died at the ripe old age of 50. In comparison, he also drank fifty cups of coffee a day, writing much of his poetry on the topic. Though, this is an extreme example. It is never recommended to drink more than four cups a day, and that is maximum in order to still maintain your health – but also getting your fix at the same time.
    To drink more than this could result in heart problems (erratic heartbeat, chest pain, enlarged heart, etc.) and can even cause dehydration and mild headaches (from increased blood flow). Though, you can look up the stats that show there are more health benefits than drawbacks associated with coffee consumption. Cheers!

  55. Coffee comes from a bean, so it contains phytonutrients and polyphenols, chemical compounds found in plants that are believed to have antioxidant benefits.
    From your brain to your bowels, coffee does work on your body. Here’s what’s really happening when you drink it.
    The caffeine enters your bloodstream and quickly finds its way to your brain, where it works as a stimulant and boosts alertness and energy.
    The downside is that drinking too much can cause insomnia.
    “If you have caffeine later in the day, it can actually predispose you to develop insomia or make it worse if you already have it.
    That’s partially because caffeine stays in your system for hours and hours.
    “The way we metabolize coffee is called a half-life,” Hunnes says. In most people, caffeine’s half-life is 4 to 6 hours. “It takes about 6 hours to reduce the amount of caffeine in our blood by about 50 percent,” she explains. So if you drink a 200 mg cup at 9 AM, by 3 PM you’ll have 100 mg left, and by 9 PM you’ll have 50 mg. Keep in mind, that’s the average half-life—how quickly you metabolize caffeine really depends on your individual body chemistry and genetics.
    Too much caffeine can have a negative impact on mood and mental health.
    High doses can mess with your brain chemistry too much, and cause jitteriness and nervousness. Studies have shown that high doses of caffeine can increase anxiety and panic attacks. Those who already struggle with these mental health challenges tend to be more sensitive to caffeine and its mood-altering effects.
    Drinking large amounts of coffee can cause a spike in blood pressure and heart rate.
    Coffee stimulates bowel movements, and may even reduce the risk of gallstones.

    In the case of tea, it’s consuming too much water, which is all that tea is. You will foremost be in the toilet all the time.
    Drinking too much water can cause a life-threatening condition called hyponatremia, which is sometimes called water intoxication. … A large intake of water in a short period overwhelms your kidneys so they can’t process and eliminate the water fast enough, which drives your blood levels of sodium too low.

  62. Most of the recent evidence I have seen suggests that the health benefits of coffee outweigh the risks, right up to the point where caffeine toxicity would happen. This is a turn around by the medics who once thought a coffee habit was as bad for you as a nicotine habit.
    Caffeine toxicity is short term toxicity. You start feeling jittery. You may get a headache. Your heart is running too fast and pounding. Your concentration falls apart. You stop drinking coffee for the rest if the day. You feel better after a couple of hours. Been there did that (once).
    Next day you moderate your intake of (good free) coffee. So unless you run yourself over the toxicity limit every day, you should be ok. And caffeine toxicity is no fun even at the time , so you don’t repeat it. Unlike truly addictive drugs like nicotine or (for some) alcohol.

  64. The most dramatic answer to that question is death . That’s pretty rare, but it can and has happened.
    A lot depends on what you mean by “high amounts of caffeine” and what the background of the person ingesting these amounts might be. Technically, a 400 mg dose of caffeine is considered an overdose, but a lot depends on how quickly a person metabolizes caffeine, their body size, and whether they usually take in that amount of caffeine.
    IRL, adults who are accustomed to drinking an entire pot of coffee in an 8 hour span don’t typically experience serious side effects unless they stop suddenly. (Some people are susceptible to caffeine withdrawal headaches which can morph into migraines with nausea and vomiting for the unlucky. I have scooped more than one relative off the floor throwing up after a hasty decision to “quit caffeine”.)
    But a regular dose of coffee delivers a pretty steady caffeine supply, and adult coffee-drinkers usually don’t have symptomatic overdoses from it.
    So who overdoses?
    With the advent of “energy drinks” and caffeine pills, the concentrated drug is more often consumed by the inexperienced, who don’t usually get a steady daily dose of caffeine. Teenagers and pre-adolescents sometimes discover these caffeine sources and ingest far too much without knowing what to expect, with disastrous results. All the effects tend to be short term, but they can be quite serious.
    Beyond the usual insomnia, caffeine overdose can cause dizziness, irritability, vomiting, fast heartbeat, headache, confusion, chest pain, muscle twitching, and even seizures. If there’s any doubt of an overdose situation in the US, call Poison Control at 800-222-1222. You can read more from Healthline (US) here: Caffeine Overdose: Symptoms, Side Effects, and Treatment

  66. In a 2018 study commissioned by the National Coffee Association , revealed that, in the United States, around 64 percent of people drink at least one cup of coffee during the day. This, of course, is a rough estimation, as the study surveyed only 3000 Americans. It is reasonable to believe that those who drink this one cup, most likely, drink a second, third, perhaps more during the day. Statistics provided by the International Coffee Organization reveals, that there are 1.4 billion cups of coffee consumed in the world. And a whopping 45 percent of them all – consumed in the United States.
    There are many reasons as to why we all should drink coffee every once in a while:
    It makes us feel more energetic.
    It can help burn fat and boost your levels of concentration.
    Improve reaction time, memory and benefit in many other ways.
    However, as it is with all things – if it gets abused it will stop serving you. And will start working against you. Even if you do not realize it in the beginning.

  67. For most of us the day starts with a nice aromatic cup of delicious coffee, but how if the same shows ill effects on your body, here we go–
    • Caffeine present in the coffee increases anxiety and disrupts sleep patterns, leading to a vicious cycle of restless sleep, relying on caffeine to help with daytime fatigue, followed by more insomnia.
    • Caffeine interacts with certain medications including thyroid medication, psychiatric and depression drugs.
    • It increases blood sugar levels, making it harder for those suffering from type 2 diabetes mellitus to manage their insulin, according to a number of studies; it also can slightly raise the blood pressure.
    • Caffeine potentially leads to some spinal bone loss in postmenopausal women if they typically drink more than three cups, or 300 mg of caffeine, a day, but don’t get enough calcium in their diet
    • Coffee itself can also mess with your stomach. If you have problems with acid reflux or heartburn, then coffee and even tea might not be right for you.
    • If there is a history of high cholesterol, it is better to trap off the cafestol, which is a compound present in the coffee that raises LDL cholesterol levels.
    It’s all about our body. People have different reactions to caffeine. Some can drink six cups of coffee a day and feel fine, others need to switch to decaf or herbal tea by noon or they’ll be up all night.

    Science has worked to investigate links — both positive and negative — between caffeine and all sorts of conditions, including cancer; this turns out out to be difficult to do because there are tons of variables to account for.
    Some are more sensitive to caffeine than others. Many people find that consuming caffeine in the afternoon or evening impacts their ability to sleep at night. This is true for me, even as a wizened old caffeine addict of 25+ years, but it’s not at all the case with some of my friends. My bestie can down the better part of a pot and then go right to bed. People are weird.
    In general, though, coffee is fairly safe even in copious quantities. For most, it’s more a question of how caffeine impacts you personally on the day-to-day than a matter of “hard” health concerns.
    One also has to consider the long-term impact of caffeine addiction, as it’s quite addictive. The number of days I’ve gone without coffee at all in the past 20 years or so can be counted on one hand, and they were all due to major surgery.

  76. What are the drawbacks of drinking too much caffeine?

    For years, doctors warned people to avoid coffee because it increases the risk of heart disease and stunt growth . They worried that people could become addicted to the energy that high amounts of caffeine provided, leading them to crave more and more coffee as they became tolerant to higher amounts of caffeine.
    Experts also worried that coffee had damaging effects on the digestive trac t, which could lead to stomach ulcers, heartburn and other ills.
    All of this concern emerged from studies done decades ago that compared coffee drinkers to non-drinkers on a number of health measures, including heart problems and mortality. Coffee drinkers, it seemed, were always worse off .
    People may become dependent on caffeine (no surprise to any regular caffeine-drinker who takes a coffee break). The symptoms—headaches, irritability and fatigue – can mimic those of people coming off of addictive drugs.

The only way to know if you consumed too much is negative side effects. These can be relatively mild (such as headache, irritability, restlessness, difficulty sleeping,…) to quite severe (elevated blood pressure, irregular heartbeat, severe GI irritability, diarrhea). The good thing is the symptoms stabilize after about 6 hrs (the typical half life of caffeine).

    Even caffeine consumed in the morning has the potential of disturbing night-time sleep.
    Caffeine has the potential of amping up anxiety in at least 2 biochemical ways:
    Caffeine triggers the adrenal gland’s fight-or-flight hormones. (The same hormones that are triggered by fear, anxiety, and stress.)
    Caffeine inhibits the calming neurotransmitter, GABA.
    Additionally, it can interfere with the production of melatonin (the hormone that tells your body that it’s time for sleep.)

    Researchers at the university analyzed the health records and the self-reported coffee consumption of 347,077 people between the ages of 37 and 73 in the U.K. Biobank .

    What are the drawbacks of drinking too much caffeine?

    The results of the study shows that people who drink one to two cups of caffeinated coffee a day had a lower risk of cardiovascular disease than people who drank decaf or no coffee at all. However, when the coffee consumption increased beyond these levels the results were different. For individuals who consumed six or more cups of caffeinated coffee a day, the risk of cardiovascular disease increased by 22 percent.
    “An estimated three billion cups of coffee are enjoyed every day around the world,” adds Prof Hypponen.”Knowing the limits of what’s good for you and what’s not is imperative. As with many things, it’s all about moderation; overindulge and your health will pay for it.”
    This research analyzed people between the ages of 37 and 73, but how much coffee is too much for a teenager? For the developing young brain, caffeine might pose a problem as it has an effect on the developmental process. According to a 2014 study in the journal Pediatrics , approximately 73 percent of children consume caffeine on a given day. Most of this caffeine comes from caffeinated sodas or energy drinks. In addition, coffee and coffee-based drinks are also an increasingly prevalent source of caffeine in children’s diets.
    Major health organizations like the American Academy of Pediatrics suggest that children under the age of 12 years should not eat or drink any caffeine-containing foods or drinks. For children older than 12 years, caffeine intake should fall in the range of no more than 85 to 100 milligrams per day. For example, a cup of Waka Coffee has about 70 mg of caffeine in a 8 fl oz cup.
    RISKS AND SIDE EFFECTS OF TOO MUCH COFFEE AND CAFFEINE

    What are the drawbacks of drinking too much caffeine?

    A typical cup of 8 oz. brewed coffee holds 70-140 mg of caffeine. Too much caffeine can lead to severe risks and side effects that would be best to avoid.
    If you are a person who has more than 4 cups of coffee per day than you should consider taking a look at these side effects. Coffee side effects include insomnia, upset stomachs, fast heartbeats, migraines, and even muscle tremors. If you love the taste of coffee, but want to reduce the amount of your consumed caffeine, try decaffeinated coffee options as well.
    Reactions to caffeine can differ from person to person based on the sensitivity one has to the substance. For sensitive people, even small amounts of caffeine (one or two cups) can trigger these effects as well. Additional factors include, body mass and anxiety disorders.
    If you are currently taking any medications, you should consult with your doctor if any of them are affected by the intake of caffeine. Some medications are prone to cause high blood pressure, nausea, and heart palpitations.

  96. I think children’s brains are continuing to develop and their bodies are still growing, limited caffeine is recommended.
    other one is Caffeine can interfere with sleep, therefore, possibly hindering proper brain development.
    Coffee makes you feel more alert, but sometimes that feeling turns into too much of a good thing. This is where the jitters come in.
    Caffeine speeds up your central nervous system, causing you to feel jumpy, according to Livestrong. Skip that fourth cup and stop the shakes.

  97. Funny you passed that question on to me… I am the only person I know who doesn’t like the smell or taste of coffee and therefore don’t drink it.
    The question in it self already defines the answer… Too much of anyrhing is bad for you.
    The question is, how much is too much?
    This depends on several circumstances, like age, sex, weight and whether you are used to taking it.
    This article I found should help you out.http://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/caffeine/art-20045678?pg=1
    Basically around 400 mg of cafein a day is ok for most. Drink more and you can get some nasty side effects, like heart palpitations and other stuff. (check that link again)
    For coffee to be lethal you would have to drink an enormous amount. For somebody of everage weight, like me (76 kilos) it would mean I’d have to drink about 70 cups in one day….
    Not really a possibility.
    So, hope this helps.

  98. Is too much xxxxxx bad for you, yes, because too much is defined by the ammount that is bad for you. It’s circular reasoning, too much anything has already become bad, by default.

  100. You catch a buzz. You get high on caffine. Its speedy. If you consume too much all the time you might get head aches. And may experience abdominal discomfort. One coffee or two are a reasonable amount preferably in the morning. Or else you will not be able to sleep well. So take it easy on the coffee. Too much could hurt you.

  101. Caffeine is a stimulant, a type of amphetamine drug, so it makes your heart beat faster, raises your blood pressure, and makes you feel more alert.
    If you consume a LOT of caffeine each day, your body tries to adapt and become accustomed to the drug, but you tend to become hyper-alert, jittery, irritable, and easily distracted anyway. Being overloaded with caffeine on a daily basis tends to interfere with your sleep as well.
    When you decide to cut back on your caffeine consumption or quit consuming caffeine altogether, you can actually go through withdrawal, like with other stimulant drugs: you tend to develop a chronic headache and crave caffeine when you try to stop having it, but if you can withstand the withdrawal symptoms you will within a week or so have it out of your system, but you may feel lethargic for a while.
    I’m relating these symptoms based on my own experience of being a heavy coffee-drinker for decades, and finally switching to decaf coffee, which still does have a tiny amount of caffeine in it.

  102. The stimulant properties of caffeine in the coffee can cause high blood pressure, a precursor to heart disease, and can cause side effects like dizziness, shakiness, headache, or abnormal heartbeat. Also makes you irritable, sleepless and may even trigger anxiety and cause diarrhoea.

  103. While the effects of caffeine as provided in another answer is something to consider, there is another potential for harm, too. Namely, the acidic nature of coffee can be detrimental to people with sensitive stomachs. After dealing with bleeding stomach ulcers, I’ve come to be much more aware of how much coffee I drink. I’ve found that, too much coffee gives me serious indigestion. I’ve also noticed that the acidity levels of different brew seem to have detrimental effect on my ulcers.
    Just something else to be aware of.

  107. There’s a famous saying by Oscar Wilde: Everything in moderation… (the second part goes, “including moderation” but that’s for another answer ). So to answer your question, too much of nothing is good for you. Too much sugar, too much salt, even too much water can be bad for your (we’re talking gallons here). First I believe what you need to understand is that what is harmful is having too much caffeine, which is found in other beverages other than coffee, such as energy drinks. Coffee can be a great way to wake up. There’s nothing like a good cup of coffee to help you start the day. But if you’re talking about getting the jitters from either too much or no caffeine, then we may have a problem. Here’s a link to the Mayo Clinic website on caffeine and coffee and you can read all about it there:
    Caffeine: How much is too much?
    If you do drink a lot of coffee (4 cups or more of brewed coffee) and you also drink other high-caffeine drinks then here are some things you may want to consider.
    When do you drink them? Are there certain times of day or certain situations that cause you to drink more?
    Do you take sugar in your coffee? If so how many teaspoons? Considering the amount of coffee you drink per day, how much sugar are you consuming in addition to the sugar you are consuming from other food products?
    Are you drinking for the caffeine or just to be drinking something hot? Could you switch to decaf?
    Are you drinking it because it is readily available and easy to access?
    What other beverages do you consume that contain caffeine in them (check the bottles and cans if you’re unsure)?
    Read about the symptoms caused by excess caffeine and coffee. Do you have any of them, such as having problems falling asleep, fast heart rate, headaches etc.
    Start keeping track of your coffee and caffeine consumption. If you don’t drink water, start carrying a bottle with you. If you don’t like water, you can get syrups that are natural and low in bad sugars or cordials. You don’t need a lot to flavour the water. If you’re buying drinks from the big names on the street, and you’re having 4 cups of mocha-choco-latte-ya-yas a day in the OMG-that-is-huge size, you may want to change that too, because then you’re bombarding your body with sugar too, and you’re probably getting a lot of energy and then crashing soon after, which may be causing you to want more and more of it. If it’s just a hot drink you crave, something to sip on while you do your work or sit in front of the TV, maybe see what else is out there? Flavoured tea sound appealing? If you love the creamy, foamy, cold coffee drinks, try making your own at home. Make a brew, use a bit of honey, maybe a bit of hot chocolate powder, use semi-skimmed milk and ice. I have this during the summer and it costs me next to nothing and it’s refreshing and indulgent, and way healthier than any frappa-wakka-hitta-loca-ccino.
    I’m not saying stop drinking coffee. But if you’re worried about your consumption think about these points and consider the caffeine in other drinks. Start by diagnosing yourself and being aware of what you drink and when you drink it. I personally have made a deal with myself. My morning coffee is something I adore and I am not getting rid of that, but during the day if I’m running around and I think I want a coffee, but I’ve already had 2, then I’ll have a tea instead. Or I’ll take a sip of my elderflower cordial flavoured water. I don’t drink energy drinks or fizzy caffeine drinks so I don’t have to worry about them. But everyone is different so make small changes, gradually, so that they’re lasting changes and not just a quick phase.
    Hope this helps!

  108. Just like anything else, you want to use moderation with drinking coffee.
    Caffeine addiction isn’t nearly as serious as many other drug addictions, but it can still cause some problems, most notably insomnia, jitters, and loss of appetite. Also, withdrawal symptoms when you can’t drink coffee for whatever reason after you are addicted aren’t fun either – headaches, increased irritability, and lethargy.
    My advice: drink one to two regula…

  109. Everyone is different. The amount of coffee that is ‘too much’ varies from person to person. Some people will get jittery, some will get acid reflux, some will get both. Others will have no noticable side effects.

  110. As the saying goes, “Everything in moderation.” There is proof that moderate amounts of caffeine are harmless for humans, and may actually be helpful. On the other hand, an excess can be dangerous. ( Warning – gross content ahead! ) I recall a science fair experiment – from back in the day when animal experimentation was still allowed – where the researcher wanted to show the effects of increasing dosages of caffeine on white albino mice. Each increase led to poorer and poorer results, until, in the last cage, the mouse was not moving at all – it was dead. Granted, that dosage was probably higher than most humans would ever ingest, but…

  111. Too much is when you are noticing symptoms like tremors, palpitations, being nervous, jittery, having problems falling asleep.
    You of course know in these last two decade many positive associations (no causation proven as yet) between drinking more than 4 cups of coffee a day and health benefits like less coronary heart disease, less diabetes, less prostate cancer has been described in the medical press:

  112. What are the drawbacks of drinking too much caffeine?

    Coffee nowadays is a great source of alertness in the morning and many of us rely on coffee during our office breaks to keep ourselves active and that’s why we do drink it more than usual without thinking about the negative consequences. Coffee has a stimulant called caffeine which causes alertness, however, excess intake of it can be dangerous for our health in the following ways:
    INSOMNIA
    It is a condition associated with the sleep disorder and a person may find it difficult to fall asleep at night and not feeling fresh in the morning. Some of the symptoms of insomnia are:
    Lying awake for a long time before you fall asleep
    Sleeping for only short periods
    Being awake for much of the night
    Feeling as if you haven’t slept at all
    Waking up too early
    ANXIETY
    Caffeine is known to increase alertness.
    It works by blocking the effects of adenosine, a brain chemical that makes you feel tired. At the same time, it triggers the release of adrenaline, the “fight-or-flight” hormone associated with increased energy.
    However, at higher doses, these effects may become more pronounced, leading to anxiety and nervousness.
    DEHYDRATION
    Dehydration is a condition caused by the loss of too much fluid from the body. It happens when you are losing more fluids than you are taking in, and your body does not have enough fluids to work properly.
    Caffeine increases the urine output, and thus more fluid is removed from the body through urination, which causes dehydration. Some of the common symptoms of dehydration are dry mouth, feeling tired and dry skin.
    RAPID HEART RATE
    The stimulatory effects of high caffeine intake may cause your heart to beat faster.
    It may also lead to altered heartbeat rhythm, called atrial fibrillation, which has been reported in young people who consumed energy drinks containing extremely high doses of caffeine.
    In one case study, a woman who took a massive dose of caffeine powder and tablets in an attempted suicide developed a very rapid heart rate, kidney failure, and other serious health issues.
    GOUT ATTACK
    People who heavily rely on caffeinated beverages increase their risk of a gout attack. Gout is an inflammatory disease similar to arthritis, where uric acid builds up in the joints and tendons causing swelling and pain.
    FATIGUE
    Caffeine helps in boosting energy levels and makes you feel active which is a positive sign but this temporary boost changes into rebound fatigue after the caffeine leaves your system. So, it is better to consume it under a moderate amount to minimize rebound fatigue.
    Consumption of caffeine under the prescribed amount seems to provide impressive health benefits in many people. On the other hand, very high dosages may lead to side effects that interfere with day-to-day living and might even cause serious health issues.

    Migraine headache
    Insomnia
    Nervousness
    Irritability
    Restlessness
    Frequent urination or inability to control urination
    Stomach upset
    Fast heartbeat

  114. What will happen if you drink a LOT of coffee all at once?
    First of all, unless it is decaf coffee, you will get the jitters, and perhaps your heart skips a beat or two.
    Secondly, you will need to pee REALLY bad. Caffein is a diuretic, which means it removes water from your system. And where does it remove it to? Your kidneys.
    Finally, you will probably be really full and not want to eat for a while. Besides you may have some difficulty in going to sleep for the next several hours.

  115. The original question I answered:

    What are the drawbacks of drinking too much caffeine?

    Tea is not specifically recommended or contraindicated for health. The only tea with any proven benefit is green tea. Any other tea has no proven benefit beyond the mental wellbeing of relaxing with a cup of tea. If you add sugar to your green tea, forget about it having much benefit.
