4hw.com.cn: many children have the problem of turning on the light to sleep. As soon as they turn off the light, they start crying. Parents have to turn on the light all the time to appease their children. But is it OK for babies to turn on the light to sleep? Let's follow Xiaobian to learn more about it~
Will the baby go to bed with the light on
It is not recommended to turn on the light when the baby is sleeping. If the light in the bedroom is too bright and the exposure time is too long, it will cause obesity, high blood fat, lack of sleep and other problems, which are also risk factors for heart health.
What's more, our brain has an endocrine organ called pineal gland. Its main function is to produce a lot of melatonin when the human body goes to sleep at night. Melatonin can inhibit the excitability of our sympathetic nerves, rest our hearts, and kill cancer cells.
One of the biggest characteristics of the pineal gland is that melatonin stops working as long as the eye sees light. The eyelid partially covers the light source, but the light source can still be felt when the lamp is turned on. Therefore, turning on the light to sleep will cause the secretion of melatonin to be inhibited, which will seriously affect our sleep quality and greatly reduce the human immune function. So turning on the light to sleep is more harmful than you think.
The harm of baby sleeping with light on
1. Reduce sleep quality
In fact, it's a kind of light pressure. Long term existence will make people restless, shorten sleep time, and reduce sleep depth.
2. Affect vision
Turning on the light to sleep will multiply the risk of myopia, especially affect the reticular activation system of children's eyes, and easily cause retinal damage. The stronger the light, the higher the probability.
3. Children are not tall
Children secrete growth hormone during sleep. When the light is on, the level of growth hormone will decrease, and then the development speed will be slowed down.
Note: the light here not only refers to the lights that are normally on, but also refers to those weak lights, such as the bedside lamp to help you sleep. It's almost the same brightness that you forgot to turn off the TV when sleeping on the sofa in the middle of the night. With these lights sleeping for a long time, the human body will produce some unhealthy changes. Therefore, parents should pay attention to that it is not good for the body to turn on the light to sleep. If children are used to turning on the light to sleep, they must correct it in time.
The reason why children like to sleep with the light on
Turning on the light to sleep is actually a fear of darkness, which is mostly from childhood. Because in this period, children love to hear stories about ghosts and gods. The background, content and characters of this kind of story often appear in the dark which is not seen by ordinary people at night to show the mystery. As time goes by, they connect the fear of ghosts and monsters with the darkness, forming a dependence on the light, leading to the fear of turning off the light to sleep, which is a main reason for turning on the light to sleep.
Secondly, in a certain dark situation, you may encounter something terrible, or you may have a nightmare in the dark. These horrible experiences can not be arranged in time, and may also cause fear of the dark. Therefore, for children who are afraid of the dark, parents should teach them patiently and guide them in time to make them brave.
