Benefits of meeting sleep standards:

1, protect your heart A study published at the general meeting of the European Society of Cardiology shows that both lack of sleep and excessive sleep are harmful to the heart. This may be because sleep will affect physiological processes such as glucose metabolism, blood pressure and inflammation, thus affecting the onset of cardiovascular diseases.

2. Enhance immunity. Poor sleep quality will have a negative impact on immunity, making it easier to catch a cold or get infected. When sleeping, the immune system usually releases cytokines. However, after many sleepless nights, the number of cytokines, antibodies and cells produced by the body with anti-infection ability will decrease.

3, it is not easy to get depression. Studies have shown that people with insomnia are 10 times more likely to suffer from depression than normal people, and are more likely to commit suicide. People with obstructive sleep apnea are more likely to suffer from depression.

People's Daily Online-American experts put forward new standards for sleep time. Adults should sleep for seven to nine hours.
