One third of a person's life is spent in sleep. As the saying goes, a person's life is thinner than paper when he sleeps three times, among which "three times" refers to lying down, eating and sleeping, and sleeping late.

First, reverse perception. As we all know, reverse sleep is the opposite of normal sleep time and normal biological clock. Its realization has this problem in many people. Some people work overtime until the early hours of the morning and start sleeping the next day. This can easily lead to endocrine disorders. Insufficient hormone secretion in the body will lead to decreased immunity and affect health. The second is a nap. Eating is eating. It is not recommended to start sleeping after meals, because the food has not been digested, which is harmful to the health. The third kind of sleep is sleeping backwards. We are all used to going to bed from early to late. People who fall asleep during the day and work at night. Reversing the biological clock will lead to endocrine disorders.

Finally, it is laziness. Almost everyone likes to sleep late. We usually go to work, go to school and get up early. We should have a good sleep on weekends to make up for the lack of sleep. However, it is easy to ignore breakfast when sleeping late, leading to hypoglycemia, malnutrition and other symptoms, and it is easy to affect the stomach after lunch. After a week's work and an occasional day off, I usually choose a lazy bed. After eating all night, there is basically no food to digest in my stomach.

Therefore, although we must ensure adequate sleep, the three senses mentioned above should be avoided, which is not good for our health.
