Many people have the experience of being too excited to sleep after drinking coffee, because there is a conductive substance called adenosine in the body, which can control nerve activity. produce slow breathing, reduced mood, reduced gastric acid secretion and diuretic effects. On the other hand, caffeine will fake adenosine, making the body think that the effect of adenosine has taken place, making you feel energetic, increased stomach acid, urinate more frequently, and naturally less willing to fall asleep. It is worth noting that the brief awakening caused by this caffeine does not mean that physical strength is really restored. In addition, everyone has a different metabolic rate of caffeine, so their sensitivity to caffeine varies, so some people don't feel that their sleep is affected after drinking coffee.
