Studies have found that sleeping with the light on is easy to get fat

A new study by Leiden University in the Netherlands found that people who turn on the light, TV or mobile phone while sleeping are more likely to gain weight.

Dr. Patrick rensen, a researcher at Leiden University Medical Center, and his team randomly divided the experimental rats into several groups and exposed them to artificial light sources for 12, 16 and 24 hours. The results showed that the body fat of experimental mice exposed to light 24 hours a day for 5 weeks increased by 50% compared with that of ordinary experimental mice. In these mice that received additional light, the absorption of nutrients by brown fat in their bodies was reduced, and the amount of fat burned was less.

Ren Sen said that there are two types of fat in the human body: brown fat and white fat. The former is responsible for storing excess heat, and the latter is converted into heat by burning fat. Research shows that artificial light not only interferes with the body’s biological clock, but also interferes with brown fat, leading to fat accumulation and obesity in the body.

Researcher Dr. Sandel kugelman said that the study once again confirmed that circadian rhythm disorders can increase the risk of obesity. The increasing prevalence of obesity is also directly related to the sharp increase in the use of electronic devices such as televisions and mobile phones that produce artificial light sources. Scientists suggest that when sleeping, try to keep the bedroom dark to avoid interference from outdoor light sources such as electronic equipment and street lamps.
