Coffee and healthy drinking coffee affect sleep

Does Coffee Affect Health?

Whether coffee affects health is a topic of great concern to many people and has been debated among scientists for years. But so far, scientific glasses have found no conclusive evidence that moderate coffee consumption is harmful to human health.

Many studies have shown that caffeine is actually beneficial in many ways. Coffee, for example, stimulates many daily activities, such as stress relief at work, a pick-me-up in preparing for homework, and so on. Moderate consumption of coffee does not affect human health, but is a good refreshing drink, almost no side effects.

Health and caffeine

There is no data showing that caffeine or coffee consumption is harmful to the body, and some studies have shown that caffeine is beneficial to human health. People often ask: How much coffee is too much? In fact, it depends entirely on the individual's endurance and habits.

A cup of coffee contains an average of 60 to 90 milligrams of caffeine, while the average human body can consume nearly 500 to 600 milligrams of caffeine a day without any side effects. Coffee, tea and Coke beans are not addictive. Although many people are accustomed to drinking these drinks for a long time, they simply like their taste and "refreshing" effect, and it is not difficult to "give up" if they really want to.

A study of 85000 nurses in the United States over a decade found no link between moderate coffee consumption and heart disease or hypertension.

Does Coffee Affect Sleep?

Many people have the experience of not falling asleep after drinking coffee. This is because there is a conductive substance called adenosine in the human body, which can control nerve activity, produce slow breathing, weak mood, reduce acid secretion and diuretic effects. Caffeine, on the other hand, mimics adenosine, which causes the body to react to it, making you feel refreshed, stomach acid increased, more frequent urination, and naturally less likely to fall asleep.

In addition, everyone metabolizes caffeine differently, and their sensitivity to caffeine varies. So some people don't feel that sleep is affected after drinking coffee. Therefore, a cup of hot coffee after getting up in the morning can lift the body and mind and make the mood more comfortable, while at night it may cause insomnia.
