In today's society, if you want to find a few people who don't stay up late, it may not be an easy task.
Because many people stay up late either because of work, study, or because of personal habits, and even some people think that as long as they sleep before 12 o'clock, they don't stay up late, even if they stay up late, it doesn't matter much.
As everyone knows, as long as it is not sleeping after 11 o'clock at night, it is already considered to be staying up late, and staying up late will directly affect the body.

After 11 p.m., the body undergoes metabolism, and many organs and internal organs are self-healing or detoxified.
If you do not sleep on time, the body can not get enough rest, it will cause the function of major organs to weaken, so that people's disease resistance and immunity decline, to create opportunities for various diseases to occur.
Therefore, anyone should try to be ready to go to bed before 10 pm and go into deep sleep before 11 o'clock to let the body better repair and rest.
If you go to bed after 11 o'clock in the evening for a long time, and the body does not get enough rest for a long time, there may be the following three obvious changes, and everyone can compare according to their own situation.
The first: skin aging. Even young people, after staying up late, there may be a phenomenon of dark circles, if you do not improve sleep in time, dark circles will be aggravated, and even long-term existence, it is difficult to eliminate. If people do not sleep until after 11 o'clock for a long time, it may also lead to endocrine disorders in the body and weakened metabolic function.
Once the metabolic function is weakened, the toxins in the human body are difficult to smoothly excrete outside the body, these toxins circulate to all parts of the skin with the blood, causing irritation to cell tissue, it may cause the skin to accelerate aging, become more and more dry, and even grow fine lines.
In this process, a large amount of pigment is deposited in the skin area, which will cause the skin to turn yellow and grow excellent spots, which will affect the appearance of the person a lot.
The second type: decreased vision. When people stay up late, their eyes cannot rest for a long time, which will lead to abnormal vision, so many people who have the habit of staying up late are myopic.
If you let yourself stay up late, it may lead to excessive damage to the nerves and cells in the eyes for a long time, causing glaucoma, cataracts and other situations.
The third: an increase in the frequency of illness. People who go to bed after 11 o'clock for a long time get sick more often than people who don't stay up late.
Because staying up late will lead to the body's organs not getting enough rest, and its function will affect immunity and disease resistance after weakening, so the body is more susceptible to bacterial or viral infections, and there are always colds and fevers.
In addition, some people are also prone to anemia, blood disorders, menstrual disorders and other phenomena.
The impact of staying up late on health is not many, if you go to bed after 11 o'clock in the evening for a long time, the body is extremely prone to the above three changes.
In addition, staying up late can also lead to cardiovascular disease and an increase in the incidence of cancer. I hope that everyone should pay attention to the harm of staying up late, do not overdraft the body, and create health risks for yourself.
Everyone should go to bed at 9 or 10 o'clock every night, enter deep sleep before 11 o'clock, ensure that the sleep time is 7 or 8 hours a day, and let the body maintain a normal biological clock, so as to maintain the health of the body.
