Does drinking coffee affect sleep?

Many people have the experience of being too excited to sleep after drinking coffee. This is because there is a conductive substance called adenosine in the body, which controls neural activity and produces slow breathing, emotional weakness, reduced gastric acid secretion and diuretic effects.

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. Therefore, a cup of hot coffee after getting up in the morning can exhilarate the body and mind and make the mood more comfortable, while it may cause insomnia at night.
