Do drinking coffee affect sleep?


Many people have experienced difficulty sleeping after drinking coffee due to mental arousal. This is because there is a conductive substance in the body called adenosine, which can control nerve activity, slow down breathing, weaken mood, reduce stomach acid secretion, and have a diuretic effect.


Caffeine can counteract adenylic acid, making the body think that the role of adenylic acid has been fulfilled, resulting in feeling energized, increased stomach acid, more frequent urination, and naturally being less able to fall asleep.


It is worth noting that this caffeine-induced wakefulness does not mean that physical strength is restored. Therefore, a cup of hot coffee after waking up in the morning can invigorate the body and mind and make the mood more relaxed, while at night it may cause insomnia.


Additionally, each person has a different metabolic rate for caffeine and their sensitivity to it varies, so some people do not feel that their sleep is affected after drinking coffee.
