There was once a popular saying on the Internet: why go to bed early when you are born, you will sleep long after you die!
In the eyes of many young people, they have enough capital to squander sleep time, after all, their bodies are still relatively healthy and young.
It's much more fun to work overtime to earn money, stay up late to play games, or watch a play than sleep. Even if the next day is not in good spirits, less rest can be recovered, and a lot of time is spent on sleep, which is a waste of life.
However, everyone ignores the point that since human reproduction and evolution, we have developed the law of life of sunrise and sunset. The purpose of sleep is to be able to allow all organs to get sufficient adjustment and rest, and better cope with the next day's life and work. Staying up late once by chance may seem to have no effect, but staying up late for a long time can cause damage to multiple systems.
So the question is, what is the difference between a person who goes to bed early and gets up early and a person who stays up late?
1. Differences in mental state
People who develop good sleep habits and adhere to them for a long time can get sufficient rest in all organs of the body, and after getting up, they are energetic and awake.
But on the contrary, a person who stays up late for a long time, because the various tissues have not received a good rest, especially the brain tissue can not be fully adjusted, is often mentally tired and weak after getting up. Staying up late for a long time will also cause a double decline in attention and memory, and even have a negative impact on emotions.
Relevant studies have pointed out that long-term staying up at night to sleep and poor sleep quality is one of the high-risk factors for depression, and insomnia and early awakening are also one of the symptoms of depression in the early stage;
2, easy to obesity
First of all, a person who has a long-term habit of going to bed early and getting up early shows that their self-discipline is very good and they have good self-control. On the contrary, a person who allows himself to stay up late often has poor self-control and is affected by body management.
Secondly, staying up late for a long time will disrupt the endocrine, reduce the basal metabolic rate, and fat is more likely to be deposited in the body. And when staying up late for a long time, it is often easy to produce hunger, and people with poor self-control may add a late-night snack, and over time, obesity will naturally find itself;
3. Physical fitness
As mentioned above, occasionally staying up late has a small impact on physical health. However, staying up late for a long time is not the same, it will cause endocrine disorders, but also affect blood pressure, metabolism, immune system and other aspects. If you lack sleep for a long time, the body's immune function will become worse and worse, becoming the object of various diseases and pathogens.
The simplest difference is that a person who goes to bed early and gets up early and is self-disciplined is often not prone to colds. However, people who stay up late for a long time are more likely to be invaded by the virus and prone to colds due to reduced immune function.
In fact, there are many studies and experiments that clearly point out that staying up late has no benefit to the body, it is one of the sources of multiple diseases, and even staying up late is related to the decline of immune function and cancer.
Therefore, everyone must not think that they are still young and have enough capital to squander. As everyone knows, the current bad habits are laying hidden dangers for various diseases in the future. Therefore, it is necessary to learn to regulate sleep time, go to bed early and get up early, and stick to it for a long time.
