One third of a person's life is spent in sleep, because only sleep can repair the organs and tissues of the body and prolong the life of these organs. If you don't get enough sleep, it will do great harm to your health. Studies have found that if you don't get enough sleep for three consecutive days, your body's immunity will continue to decline, and at this time, some diseases will take advantage of it. Moreover, if people don't get enough sleep, they will have no energy and look tired. Insufficient sleep affects not one organ, but the whole body. Under the condition of insufficient sleep, all organs of the body are overloaded, so health is very prone to problems.
In fact, everyone knows a little about the harm of lack of sleep, but there are still many people who don't care very much, which leads to the phenomenon of lack of sleep for some young college students now, because evening time is more free for them and there is no limit to playing games and entertainment. Therefore, they borrow time from sleep, preferring to reduce the time of sleep and have fun as much as possible. They think they are still young and will not have any health problems. In fact, these changes in the body are gradual. Among middle-aged and elderly people, some organs will age ahead of time and more diseases will occur.
What harm can lack of sleep do to the body?
1, damage the liver.
Lack of sleep first harms the liver and gallbladder, because our liver needs time to repair every night. The general repair time is 23:00-65438+ 0: 00 am. If you don't sleep for a long time, it will lead to increased liver pressure and cause various liver diseases.
2, harm the gastrointestinal tract.
If you don't sleep well at night, you will get hungry and always want to eat. Eating food at night will increase the burden on our gastrointestinal tract, and over time our gastrointestinal tract will have problems.
3, sad.
We often say that staying up late is a kind of painstaking work. Poor sleep will directly damage the health of the heart, because only in the state of sleep will our heart beat slowly and repair itself. If you don't sleep, your heart will keep beating very fast, which will increase the burden on your heart and make you prone to cardiovascular and cerebrovascular diseases.
4, endangering the human immune system.
The body has a strong immune system to stay away from many diseases, and long-term lack of sleep will lead to a decline in the ability of the immune system. At this time, inflammation and cancer are easy to find.
5, damage the nervous system.
Lack of sleep will affect the nutrition of nerves, and then affect the conduction of nerves, leading to memory loss, judgment loss, and some emotional changes, which will easily lead to depression and temper tantrums. Long-term lack of sleep is also prone to depression.
