Last Updated: 2026/04/06, Many people have the experience of not sleeping because of high spirits after drinking coffee. This is because there is a conductive substance called adenosine in the body, which can control nerve activity, produce respiratory slowdown, mood reduction, acid secretion reduction and diuretic effects. Caffeine, on the other hand, fakes adenosine, making the body think that the effects of adenosine have occurred, leaving you feeling refreshed and stomach acid increased.

Many people have the experience of not sleeping because of high spirits after drinking coffee. This is because there is a conductive substance called adenosine in the body, which can control nerve activity, produce respiratory slowdown, mood reduction, acid secretion reduction and diuretic effects. Caffeine, on the other hand, imitates adenosine, making the body think that the effects of adenosine have occurred, making you feel energetic, acid increased, more frequent urination, and naturally less able to sleep. It is worth noting that this brief wakefulness caused by caffeine does not mean that physical strength has really recovered. In addition, everyone's metabolic rate to caffeine varies, and their sensitivity to it varies, so some people don't feel that sleep is affected after drinking coffee.
