We have already talked about the numerous beneficial properties of coffee and the energizing effect it has on our body. Many people, in fact, without a good cup of coffee early in the morning are unable to fuel, unable to get out of the stupor of sleep and face the day.
But there are other people who can also drink a coffee in the evening, just before going to bed, and still be able to fall asleep ... Why, then, does coffee not have an effect for some people?
In fact, many ask themselves "why does coffee not affect me"? This could be a problem when you need an extra charge to stay awake and active, perhaps in moments of mad and desperate study or when you have to face a tiring day at work. So let's see when the coffee has no effect.
Who doesn't love coffee?
The answer is in the metabolism; those who think coffee has no effect is because they have a very fast metabolism, therefore the caffeine taken is quickly disposed of through the urine and the liver system, thus quickly losing the energizing effect of caffeine.
This ability to halve a substance in our body is called half-life. Those who stay awake after coffee consequently have a very slow metabolism which takes longer to eliminate caffeine from the circulation.
Furthermore, drinking coffee regularly can lead to a certain addiction, that is, our body tends to tolerate it so well that it no longer has a strong effect, a significant consequence on the body.
On the other hand, those who take small doses of caffeine and above all sporadically, perceive small problems of insomnia and agitation.
The explanation for the fact that coffee has no effect for some people has scientific foundations, it certainly does not depend on emotional or psychological conditions.
Therefore, those who have a slow metabolism but want to drink coffee in the evening should chose decaffeinated coffee to avoid the risk of staying up all night!
