Many experts believe that the basic ways to improve physical health are healthy diet, proper exercise and adequate sleep. According to the 2017 Nobel Medical Awards, among these three, sleep is the most important. Many epidemiological studies show that the shorter the sleep time, the shorter the life; therefore, if you want to stay healthy and have a long life, you need to sleep more.
In fact, many diseases are related to insufficient sleep, the most common of which are cardiovascular diseases, obesity, diabetes, depression, anxiety, dementia in the elderly, cancer, etc. If you sleep less than 7 hours, your immune system and cognitive ability will begin to be affected; if you don’t sleep for 20 hours, you will have a drunk reaction.
When people sleep, their bodies and organs also take advantage of rest and repair. For example, their heart rate will drop significantly, 10 to 30 times less than when they are awake. In a different sentence, sleep can be said to be the rest time of the heart. After falling asleep, the peristalsis of the stomach slows down, and the life of gastric mucosal epithelial cells is very short, and they will be reborn every two or three days. This replication and repair process is also carried out during night sleep.
The muscles in the body will relax and relax when they are asleep, and at the same time, they secrete growth hormones to restore and rebuild the body's tissues to promote muscle regeneration. The brain is a highly and delicate brain cell activity, which produces a large amount of cortical waste during the process, and requires brain marrow fluid to clear them. Only when sleeping, brain cells become smaller, leaving spaces to allow brain marrow fluid to flow and take away these wastes.
