The harm of women sleeping with the light on

For women, going to bed early and getting up early is not only good for your complexion but also for your physical health. When women sleep with the lights on at night, it will not only cause visual light pollution but also make themselves dependent. They will not dare to sleep in a dark environment and it will be difficult to distinguish between day and night. If this continues for a long time, their bodies will gradually develop health problems and their sleep quality will not be good.

Sleeping with the lights on is a bad habit. It means people develop a fear of dark environments and a dependence on light, which leads to a fear of sleeping with the lights on.

1. Inhibit the body's leg and pigment secretion, increasing the risk of cancer

Studies have found that there is a pineal gland in our brain, which can secrete melatonin when the human body enters sleep time at night. Melatonin has a huge effect on the human body. It can not only lower blood pressure and slow down heartbeat, but also enhance our body's immune ability. Without melatonin, the cancer cells and tumor cells in the body will rapidly fission and grow, and the destructive power to our DNA will increase exponentially, which will greatly increase the risk of cancer.

2. Cause children to have precocious puberty

Under normal circumstances, the secretion of hormones in our body has a fixed time point. For example, the highest secretion time of androgen should be around seven or eight in the morning, which is when the light conditions are better. Experts tell us that too long exposure to light will lead to a decrease in the amount of melatonin secreted by our bodies, causing the premature secretion of follicular estrogen in girls, so the child's breasts will swell prematurely and other sexual organs will develop prematurely.

3. Children’s glasses have problems

The harm of sleeping with the lights on is more likely to occur in children, especially infants or young children. Nowadays, many new mothers like to sleep with the lights on at night to facilitate breastfeeding and taking care of their children at night. But what people don’t know is that too strong light will damage the newborn baby’s eyes. Causes serious damage to eyesight.

The latest research results show that if children under the age of two sleep with the lights on, the chance of them developing myopia in the future is 34%. If they still sleep with the lights on after the age of two, the chance of them developing myopia in the future is 55%. However, the chance of children who sleep with the lights off is only 10%.

Experts tell us that the critical period for a baby's vision development is between two and three years old, and the lighting environment at this time plays a decisive role in the child's future vision. Keeping the lights on for a long time will prevent the pupils from truly relaxing and resting, and the nerves and muscles in the eyes will always be tense. In addition to the high probability of myopia, the hazards of sleeping with the lights on for a long time also include increasing the probability of cataracts, etc.

4. Causes imbalance of yin and yang in the body

From the perspective of traditional Chinese medicine, the human body is in a state of repair when sleeping, allowing our body and mind to reach the best state. In other words, humans need day and night so that the body can achieve the optimal state of yin and yang balance. Sleeping with the lights on will disrupt the meridians in our body, so people are prone to feeling tired and unable to get the best rest. The harm of sleeping with the lights on at night can cause neurasthenia and insomnia at the mildest, and internal dysfunction, cancer and so on at the worst.

5. Light pollution

The results of the study found that if women are under the light for a long time, their chances of developing breast cancer will increase exponentially, and the risk of prostate cancer will also increase. The harm caused by turning on lights at the right time is very serious, especially when suddenly turning on strong headlights. As early as 2007, the World Health Organization classified night shifts as a health risk.
