Ecological sleep:

Sleep is a kind of culture, because people's long-term sleep process forms the values and habits of sleep. These are not caused by instinct. Human energy comes from diet and sleep, so sleep culture will be better guided. People enjoy a more comfortable sleep, and the existence of a healthy sleep culture is necessary.

If calculated by day, a person's life is about 30,000 days, one third of the time is spent in bed, then it is 10,000 days. If the person's sleep time is about 27 years, many people sleep. The time may reach or exceed 30 years. According to the latest survey by the China Sleep Research Association, the incidence of sleep disorders in adults in China is 40%. The current population is calculated at 1.4 billion. About 600 million people in the country have sleep disorders.

Poor quality sleep can even endanger human health. Sleeping on time and going to bed early and staying up late is the beginning of a healthy sleep.

At the beginning of the 20th century, people averaged about 9 hours of sleep per day. By the beginning of the 21st century, people had an average sleep time of only 7 hours per day, a reduction of 2 hours, and because of overtime watching TV and playing games and other entertainment activities. Many people only have 4-5 hours of sleep a day, which seriously affects people's metabolism and reduces the body's immunity. Over time, it will affect people's health and affect people's life.

Scientific research proves that adults need to maintain 7-8 hours of sleep every day, in order to ensure the normal metabolism of the body, the immune system and the brain can be repaired in time, in order to maintain good health and vitality, thereby extending life expectancy.
