Sleep directly affects health and longevity, when sleeping too little or too much, it increases the risk of serious illness.
Sleep is a necessary physiological activity to maintain the normal functioning of the body. During sleep, the body restores cells, regulates hormones and maintains the functioning of the nervous system. These functions are closely related to the risk of disease and life expectancy.
Adults should sleep 7 to 8 hours per night. This is a suitable time to help the body maintain a stable state. If you maintain a sleep time lower or higher than this level for a long time, your health may be affected.
Effects of sleep deprivation
Lack of sleep disrupts important bodily functions. When sleeping less than 7 hours per night, the body may experience metabolic disorders, immunodeficiency and hormone imbalance.
This condition increases the risk of diseases such as obesity, diabetes, heart disease and high blood pressure. At the same time, lack of sleep also affects the mind, increasing the risk of anxiety and depression.
In addition, lack of sleep reduces concentration and reflexes, thereby increasing the risk of accidents in daily life and when participating in traffic.
Effects of oversleeping
Sleeping too much can also be detrimental to health. People who sleep more than 9–10 hours per night are at higher risk of stroke than those who sleep enough.
Prolonged sleep time may be related to sleep disorders or undetected health problems. In addition, people who both sleep a lot at night and have prolonged naps are also at higher risk of stroke.
Therefore, sleep duration needs to be maintained at an appropriate level. Sleeping too little or too much can negatively affect health.
The role of sleep in the body
While sleeping, the body repairs tissues, strengthens memory and regulates endocrine activity. Sleep also supports the immune system and helps maintain heart and brain function.
When sleep is not enough or interrupted, these processes do not take place fully, thereby increasing the risk of disease and affecting long-term health.
Sleep time and health
Maintaining sleep for about 7-8 hours each night helps reduce the risk of disease and supports the body to function more effectively. Conversely, sleeping too little or too much for a long time can increase the risk of death.
This shows that maintaining a reasonable sleep habit plays an important role for overall health.
How to improve sleep
To improve sleep, you should maintain a fixed bedtime and wake-up time every day. Avoid using electronic devices before bed and keep the bedroom quiet, dark and airy.
In addition, it is necessary to limit caffeine and alcohol in the evening, and maintain regular physical activity. These habits help improve sleep quality and support long-term health.
