what happens when you drink coffee?

So when you drink coffee, you produce adrenaline (= epinephrine and norepinephrine) which allows your brain to literally work faster. That's why you feel smarter, brighter, more productive etc. Messages can pass in your brain more rapidly.


It overwhelms your system. You start to have too many thoughts too fast. That's great and all when adrenaline is supposed to be produced, in fight-or-flight situations where you actually need to observe your surroundings and make quick decisions. In everyday life it's just extra stress on your system. It overwhelms your brain.

So whatever amount of anxiety you have (and everyone has some :) ), caffeine multiplies it. It can be hard to notice because it also kinda makes you feel more alive, for a moment.
