Non-rapid eye movement sleep is divided into four stages: light sleep, light sleep, middle sleep and deep sleep.

What are the dangers of too little deep sleep

Sleep is a biological instinct. When a person is sleeping, the muscles of the whole body relax and the response to external stimuli is reduced, and activities such as heartbeat, breathing, and excretion are reduced. Reduction is beneficial to the recovery of functions of various organs. The biological clock in the human body controls the endocrine system and releases various hormones. Among them is a growth hormone, which functions to promote muscle metabolism, restore physical strength, and promote bone growth.

During the baby period, the secretion of this hormone shows a pattern of more nights and less days. The growth hormone released between 1 pm and 5 am is almost three times that of the day. Obviously, if the baby goes to bed late for a long time, it will definitely affect the normal physiological secretion of growth hormone, which is quite detrimental to growth and development, especially the height. < /p>

Therefore, in order for babies to grow and develop healthily, parents should arrange a regular schedule for them, develop the habit of going to bed regularly at night, and ensure adequate sleep time. What is deep sleep 2

The first cycle is divided into light sleep, light sleep, middle sleep, and deep sleep. After this cycle ends, it will enter another cycle, which is deep sleep.

Sleep is an instinct of the body. During sleep, all the muscles of the body are in a relaxed state, and the response to external stimuli is relatively low, and heartbeat, breathing, excretion and other activities will be greatly reduced, resulting in All organs can be given time to repair. The body's biological clock is inseparable from the endocrine system, which releases various hormones, especially growth hormone, to promote the body's metabolism.
