Each of us goes to bed at night. Some people always insist on going to bed early and getting up early, and their mental state will be much better, while some people often stay up late to practice immortality. But has anyone ever thought about why people sleep, what will happen if they don’t sleep, and what will happen if they stay up late for a long time? What will happen to the body? Let’s find out together!
Why Do People Sleep?
In high school, some schools had some inspirational slogans similar to "Why sleep long before death, and sleep forever after death." But in fact, sleep is very important to us, and not sleeping or going to bed late will make people feel uncomfortable. Staying up late may even cause endocrine disorders, acne, hair loss, and other consequences.
Our human body is constantly working during the day, so even if we just sit still for a long time, we will feel tired. This is because the various organs in our body are tired. At this time, we can let them rest by sleeping. In this way, we will wake up more energetic the next day.
Some scientists believe that sleeping is to preserve energy, reduce basal metabolism, and restore the energy consumed during the day by sleeping and resting. It is similar to the hibernation of some animals, but they sleep all winter, and we just sleep every night.
Children will also grow and develop during sleep, while adults use sleep to repair nerve tissue, and protect and consolidate memory, in a sense, sleep can strengthen our memory, sleep can affect our brain capabilities, slow down aging, and prevent brain diseases.
At the same time, when we sleep, our bodies will also have a metabolism, and they will repair some damage caused during the day. Therefore, after running 800 meters in a physical education class, most of us will wake up with backaches the next day. This is because our bodies are repairing themselves while sleeping.
If we stay up late without sleeping for a long time, the balance of energy metabolism will be broken, and many changes will occur in the human body. Our body temperature will be disturbed, and our immunity will decline. At this time, as long as there is a little wound, we will be infected, and in severe cases, it may even be life-threatening.
