Staying up all night does nothing! What time does it count to stay up late? The doctor's answer is surprising
In ancient times, people paid attention to "work at sunrise and rest at sunset". However, in modern society, there are very few people who have regular work and rest. Sleeping late has gradually become one of the living habits of young people. Everyone in the circle of friends is striving to be the "stay-up champion", and staying up late has become a common phenomenon. .
It is true that staying up late can bring temporary pleasure to the body and mind, but staying up all night is ultimately harmful to nothing.
What are the possible consequences of staying up late? To sum up, the main points are as follows.
- Damage the eyes
The reason for staying up late is either work or study, drinking or playing games, or watching TV shows, and doing these things is undoubtedly overloading the eyes. In addition to the dark light at night, the eyes will become sensitive, fragile, swollen and dry. , Red blood cells increased, but also caused a significant decline in vision.
- Cause obesity
People tend to go to bed later, consume more energy, and get hungry more easily. When people go to bed without digestion after eating late at night, the calories in the food will be converted into fat and accumulated in the body. If things go on like this, it will be difficult to control the weight, and obesity will follow.
- The speed of aging is accelerated
Staying up all night deprives all organs of the time for detoxification and metabolism at night. Toxins can not be excreted in time and will be reflected on the skin, causing people to look worse, rough skin, enlarged pores, dark lines, and acne and spots. Accelerate aging.
- Deterioration of physical fitness
Staying up late will destroy the balance of the human body, cause various system dysfunctions, resulting in decreased immunity, endocrine disorders, and reduced fertility. It will also increase the risk of diabetes, hypertension, neurasthenia, and various cancers, and even lead to sudden death. Therefore, staying up late is actually overdrawing your life.
- Reduced learning and work efficiency
Insufficient sleep time can cause dizziness the next day, lack of energy, difficulty concentrating, drowsy during study and work, and often staring at the same place in a daze. Staying up late for a long time will also lead to a decline in memory, agility and flexibility of the brain, which is not conducive to improving the quality and efficiency of study and work.
People often shout to put an end to staying up late, but do you really know what "staying up late" is?
In the inherent concept, not going to sleep in the early morning is staying up late, this kind of thinking is actually a bit too one-sided.
First of all, you must know that there are two main criteria for defining staying up late: whether you get enough sleep and whether it is regular.
Strictly speaking, as long as you get enough sleep according to your age and develop a long, stable and regular work and rest habit, you are not staying up late. Even if you sleep late, it can only be said to delay your sleep time.
For example: a normal adult needs about 8 hours of sleep per day. As long as people get enough sleep for 8 hours and develop a regular biological clock, they are not staying up late, that is to say, even if everyone sleeps at 3 am every day No problem from 11am.
But if people sleep less than 8 hours, or even if they get enough sleep, the time period of sleep is different every day, such as going to bed at 22 o'clock today and going to bed at 2 o'clock tomorrow, then it should be counted as staying up late.
All in all, what time to sleep is to stay up all night depends on what time you wake up the next day, and on this basis, it is judged by the double standards of whether you have enough sleep and whether it is regular.
Having said that, I hope that everyone can go to bed early and get up early, and work and rest regularly, because this is not only in line with the public's living habits, but also allows the body to get a reasonable rest.
In addition, I also want to remind everyone that you must not spend your energy on staying up late for whatever you want because you are young. After all, the harm caused by staying up late will not detour for the sake of everyone's youth and strength.
