In fact, the longer the human body is exposed to artificial light, the less nutrients it absorbs and the less fat it burns, which will easily increase the risk of obesity and lead to three highs. There are two kinds of fat in human body, white fat and brown fat. The human body gets heat by burning white fat. When the human body has excess heat, it will turn into brown fat.

However, artificial lighting will interfere with brown fat, affect the deposition of excess fat, and form obesity over time. So turning on the light at night not only affects the biological clock, but also increases the risk of obesity. The biological clock in the human body changes rhythmically. Artificial lighting is different from sunlight and ultraviolet rays, which will lead to the disorder of the biological clock and increase the occurrence of some chronic diseases.

2. Insufficient secretion of melatonin

Obesity is related to the long-term use of artificial lighting products such as mobile phones and televisions. Dr. Tomato reminded that turning on the light to sleep at night will also greatly reduce the secretion of melatonin in the human body, leading to dull skin color, which is caused by improper daily habits.

The best way to sleep is to keep the bedroom dark 1 hour before going to sleep, so that the body can release melatonin before going to sleep. At the same time, minimizing the interference of electronic products such as mobile phones and reducing the time of exposure to artificial lighting will help reduce the risks of obesity, neurasthenia and insufficient melatonin secretion.
