If adenosine is immobilized and immobilized, cells in the nervous system become over-excited, the expert explained.
Another study found that the stimulant effect of caffeine can last up to 15 minutes and last up to 6 hours.
This proved the stimulant effect and persistence of caffeine, and in the market caffeine turned into a socially acceptable psychotropic drug.
