  1. I work for product engineering team which involves lots of interactions, meetings, deadlines. I’m not regular to Cofee neither he is. Couple of days back I returned Bangalore after hectic business trip. Change in weather, trip took toll on my health, I promised a lot to customer and they were expecting lot from me. I had sore throat, nose block and I had an important meeting I was not at all feeling like taking up meeting. I felt like drinking Cofee, I went to cafeteria in the rain and I had nice Cofee, Bingo my energy was restored, I felt better to talk and I did non stop for the next one hour!
    That’s Cofee for you my friend!

  2. No. But it can make you more effective with your smarts.
    One of the effects that caffeine provides that is not mentioned in the first four answers is that caffeine provides a stimulus-barrier benefit. For people working in a noisy and chaotic environment, this effect can be huge. For example, if you work in an open office like a newsroom where everybody else is on the phone, talking with each other, faxes and phones are ringing, and the boss is screaming at somebody, coffee can really, really help you concentrate by lowering your sensory sensitivity to such distractions. But if you are in a quiet library or the privacy of your own house, this may not be particularly important. I think the stimulus-barrier effects of coffee are why “coffee breaks” became iconic in the American workplace.

  3. Quite the contrary – as per this article The effect of daily caffeine use on cerebral blood flow: How much caffeine can we tolerate? , too much caffeine intake can reduce the cerebral blood flow. This may lead to reduced cognitive function.

  4. Actually smarter? No.
    Actually more motivated? Also no.
    Effectively both, because you are alert, at least compared to your non-caffeinated state? Yes.
    The real problem is that we tend to compare “coffee vs not-coffee” over a time period of hours. You would really need to compare the two states over months, with a six-week washout period in between, with additional changes in sleep and diet to replace the jolt you get from coffee.
    I am not willing to do this experiment on myself. Feel free to report your results.

  5. Forty years of heavy consumption and I’m still waiting for the ahah! (cue lightbulb) moment.
    All caffeine does is stop acetylcholine reuptake, increasing nervous activity for a short period of time.
    An analogy is like comparing a turtle to a hare.
    The turtle always wins, but the hare gets to have more fun.

  6. I have had intense coffee drinking times. In school i sometimes drink upto 20 cups a day and one cup has atleast one tablespoon of coffee. Am still waiting for the day I will wake up and feel brainy like “wow! I feel supersmart.
    Coffee is a stimulant. Keeps you awake and energized so you can work better. Helps me feel like I’ve just come out of a really nice shower but it doesn’t make me feel smarter.

  7. Actually, caffeine just make you more alert. Nothing more. Caffeine is a drug that acts as an agonist of adenosine in the brain, thus preventing you from drowsiness, making you more alert.
    As you are more alert, of course you can experience a feeling of being more active, awake, motivated and smart. But you really are not: you are just experiencing that feeling when you awake from a good rest and want to do a variety of things.
