Anonymous users2024-02-12We spend most of our lives sleeping, and if we remove it, then our lives will increase directly1 3. But why do we want to sleep?
The human body is a delicate instrument, and sleep plays a vital role in the repair of this instrument. In other words, during sleep, we repair the brain cells and other tissues that are consumed during the day, so that we can stay in good shape to meet the challenges of life in the future.
Sleeping is a common human activity. However, the process of sleep and what causes drowsiness has not yet been clarified. The pineal gland in the thick layer of the brain is important because a chemical called melatonin is produced here.
This substance enters the bloodstream and controls the cycle of sleep and wake-up.
Scientists have found that human sleep can be divided into two types, namely fast-wave sleep and slow-wave sleep. The most obvious difference is that one produces dreams and the other does not. These two types of sleep are what we commonly call light sleep and deep sleep.
Sleep is a common phenomenon in animals, and its main function is to effectively repair brain tissue. In the process of human metabolism, a metabolite called free radicals is produced, which is extremely harmful to the nerves of the brain, which in turn can cause memory loss and sluggishness. At this time, our central nervous system will give certain instructions to let us rest, so as to better repair nerve tissue cells and remove the harm caused by free radicals.
At the same time, scientists have also found in the process of research that if they do not get enough sleep for a long time, some people will have more serious sleep debt.
In general, adults should sleep at 7 to 8 hours a day. However, many workaholics or game freaks do not care about their bodies at all, and over time, they have a very serious sleep debt. Just like many students who leave the examination room after the college entrance examination, go home and sleep for three days and three nights, mainly to effectively compensate for the sleep debt owed at the beginning.
If sleep is not effectively replenished, it will seriously affect our normal life.

If you want your child to sleep on his own, it is recommended that you do it step by step, without rushing, and give your child an adaptation process. If you don't want to share a bed with your child, you can add a small bed next to the queen bed and let your child share the bed first. A child with a sense of security is willing to try all kinds of things that are unfamiliar to her, because he knows that as long as he looks back, he can see his parents waiting for him and know that he is not alone.
