Why do coffee drinkers feel more clear headed after consuming caffeine? Why do some get a headache without it? Does caffeine cause any permanent brain changes and can the brain go back to ‘normal’ after years of caffeine use?
In: Biology
As far as we can tell there is no long term changes done by consuming caffeine. The changes we see is mostly related to the body adapting to the caffeine by getting more tired on a normal bases. Think of it as producing anti-caffeine to negate the effects. So people who are addicted to caffeine needs caffeine to stay awake and alert. So the “correct” way to drink coffee is to only drink it when you need the extra boost to stay awake and alert but no not drink it more then maximum a couple of times a week.
