Some people always like to sleep with the light on. See the following points, and you will collapse. It's time to turn off the lights. Dr. jared Bang Qi, an expert from a heart research institute in the United States, has written many research reports, pointing out that too strong light and too long exposure in the bedroom will lead to obesity, hyperlipidemia and lack of sleep.

A Japanese researcher asked 528 people to do this experiment. The bedroom where the first group is located is dark, less than 3 lux (light unit); In the control group, the bedroom illumination is greater than 3 lux. After a period of time, the results showed that the average weight of the control group increased by 4.4 pounds (about 2 kilograms) and the waist circumference increased by more than 2 centimeters. Long-term light will increase the proportion of "bad" fat.

As we all know, sleep quality is closely related to health. Children, in particular, should maintain good sleep quality to promote their development and healthy growth. Some children are afraid of the dark, and many parents leave a light when their children sleep. Long-term exposure to these artificial light sources will affect the normal secretion of growth hormone, which is very important for children's growth and development. In addition, long-term light will affect children's mood, especially babies. Strong light will make them cry and it is difficult to sleep.

Generally, between the evening of 10 and 2: 00 am, the secretion of growth hormone is the most vigorous, and the lighting environment at this time should not be too bright. In addition, children secrete melatonin during sleep. Melatonin is a natural substance to promote sleep, which can make people gradually relax and enter deep sleep. If you sleep with the light on for a long time, it will affect the normal secretion of melatonin, thus reducing immunity. The secretion of melatonin usually peaks at 2-3 am, and the level of melatonin at night directly affects the quality of sleep.

In terms of vision, when you sleep with the light on, the light will stimulate your eyes, and it is difficult for your eyes to relax completely. Even if you close your eyes, your nerves and muscles will still be in a tight state, making it difficult to enter a deep sleep. For the baby, every organ is fragile, which will stimulate the retina under strong light, thus affecting vision.
