1: Breast cancer. Studies have shown that darkness in the bedroom while sleeping minimizes a woman's risk of breast cancer, so it is best for women to sleep at night with the lights off to prevent breast cancer.

2: Depression.

According to an academic report published overseas in 2013, patients with depression have a higher tendency to sleep with the lights on than normal people.

In addition, according to a study by Kenshi Ohbayashi, an associate professor at Nara Prefectural Medical University, sleeping with the lights on at night tends to disrupt the body's biological clock, and the most effective way to prevent depression is to fully sunbathe during the day.

3: Obesity.

The University of Oxford in the United Kingdom has conducted a survey on the obesity of women who are used to sleeping with the lights on and when the lights are closed, and the results show that the BMI value (the value that indicates the degree of obesity) of women who are used to sleeping with the lights on is relatively higher, and the waist circumference is relatively larger.

In addition, Nara Prefectural Medical University also announced that sleeping with the lights on at night increases the risk of obesity. Therefore, for those who wish to **, it is important to pay attention.

1. You need to turn off the lights to rest when you sleep at night, on the one hand, it is conducive to sleep, so that the eyes can fully rest, and on the other hand, it is conducive to the formation of melanocytes in the dark.

2. The harm of sleeping with the light on is not conducive to the recovery of eye fatigue, and sleeping with the light on for a long time is easy to cause dry eye eye fatigue, and it is not easy to fall asleep, which seriously causes insomnia, and also has adverse effects on the formation of melanin. Human health needs to follow the laws of nature, be consistent with nature, and need to turn off the lights to rest at night.

Sleeping with the lights on can cause obesity because sleeping with the lights on can interfere with the decomposition of brown fat in the body and the white fat in the body as heat, resulting in fat accumulation. And it will also lead to the early development of female sexual organs, and in the case of sleeping with the lights on for a long time, the chance of cancer will also be greatly increased.

Causing obesity is one of the main harms of women sleeping with the light on, because there are two kinds of fat, brown and white, white fat will store excess heat in the body, brown fat will break down white fat as heat, if you sleep with the light on, it will interfere with brown fat, which will lead to fat accumulation in the body and cause obesity.

There is a fixed time for hormone secretion in the human body, for example, the highest time for male hormone secretion is 7 or 8 o'clock in the morning, and too long a light time will cause the follicle estrogen secretion in a woman's body in advance, and a woman's sexual organs may develop early.

The pineal gland of the human body will secrete a large amount of melatonin from 11 p.m. to the early morning of the next day, which can enhance the body's immunity and kill cancer cells.

1. Sleeping with the light on at night is more harmful to the body, first of all, it will affect the quality of sleep, and sleeping with the light on will not make people relax, which will lead to difficulty falling asleep, thus affecting the quality of sleep.

2. Secondly, it will reduce immunity, the brain will secrete melanin after entering the sleep state, melanin can reduce blood pressure, slow down the heartbeat, and the heart will be rested, so that it can enhance the body's immunity, but the brain will not enter the sleep state when the light is turned on, and there is no help to improve the body's immunity. Again, it will damage the eyesight, and sleeping with the light on is easy to cause damage to the retina of the eye.
