How does sleep affect hormones

Sleep allows the organs in the body to rest after working all day. If you don’t get enough sleep or your sleep time is irregular, it will have a great impact on the body’s hormone secretion. For example, lack of sleep can lead to an increase in pimples and acne on the face.

1. Influence on the brain's creative thinking. Researchers believe that in order for the human brain to think clearly and react quickly, it must have sufficient sleep. If the brain does not get enough sleep for a long time, it will affect the brain's creative thinking and ability to handle things.

2. Influence on the growth and development of adolescents In addition to factors such as genetics, nutrition, and exercise, the growth and development of adolescents is also related to the secretion of growth hormone. Growth hormone is a hormone secreted by the hypothalamus that promotes the development of bones, muscles, and internal organs. Because the secretion of growth hormone is closely related to sleep, that is, there is a large secretion peak after a person falls asleep, followed by several small secretion peaks, while in the non-sleeping state, the secretion of growth hormone decreases. Therefore, if teenagers want to develop well and grow taller, they must get enough sleep.

3. Influence on skin health The reason why human skin is soft, smooth and lustrous is that it relies on the capillaries in the subcutaneous tissue to provide sufficient nutrition. Lack of sleep can cause stagnation of skin capillaries and obstructed circulation, making it impossible for skin cells to get adequate nutrition, thus affecting skin metabolism, accelerating skin aging, and making the skin appear dull and pale. Especially the eye circles become dark and wrinkles easily appear.

4. Leading to diseases. Frequent lack of sleep will make people feel anxious and worried, and reduce immunity, which will lead to various diseases such as neurasthenia, colds, gastrointestinal diseases, etc. Lack of sleep can also cause increased blood cholesterol levels, increasing the chance of heart disease; most of the cell division in the human body occurs during sleep, and lack of sleep or sleep disorders can affect the normal division of cells, which may cause cancer cell mutations and lead to the occurrence of cancer. Generally speaking, people of different ages need 8-9 hours of sleep a day. Adults need 7-8 hours of sleep a day.

5. Lack of sleep can cause obesity. Relevant studies have shown that lack of sleep can lead to a decrease in the concentration of lipoprotein in the human body. Lipoprotein is a substance that moves in the blood system and has the function of suppressing appetite, which can influence the brain to decide whether to eat. Lack of sleep can also cause an increase in the concentration of appetite hormones in the human body. Orexin is a substance secreted by the stomach that can induce a person's desire to eat. When these departments in the human body that control "appetite" conflict with each other, the brain's decision-making system may make wrong decisions.
