A cup of coffee can be magical if we drink it at the right time
A 24-hour hormonal cycle, called the circadian cycle , is what tells our bodies when to eat or when to sleep .
One of its tasks is to release cortisol, a substance that helps us feel awake and alert.
If you drink caffeine at the time of highest blood cortisol level, it is the same as taking medication when you do not need it: it will have no effect and your body will generate resistance to that substance.
The ideal time to take it , according to experts, would be between 9:30 and 11:30 a.m. and between 1:30 p.m. and 5 p.m.
