Sleep: “The right duration is 7×7, 7 hours a night, every night”

Indeed, Adam, naps allow you to recharge the batteries. But be careful, not just anytime or how. The ideal is to take a nap in the early afternoon, for about twenty minutes. If you drink coffee, it is best to take it before your nap, the caffeine will have taken effect when you wake up. But besides, who says nap, does not necessarily say sleep at all costs. It can be a moment of calm, where you close your eyes, rest, think about something else, clear your mind. I imagine that at 17, you are in class, which is not (I hope) conducive to naps… But between two classes, you can take a few minutes of rest or just a breath of fresh air, c is very effective.
