Night light and obesity

Scientists identify: the time you eat also plays an important role as what you eat during the day, because when you stay up late and expose to the light in the night, you will easily get fat. more fertile than others.

According to recent research results, mice exposed to light with different light intensity developed faster and heavier than mice that spent 8 hours a night in the dark.

In fact, the main reason for obesity is not light but because the biological clock is disturbed . In plants, biological clocks signal when they grow. In humans, the biological clock helps regulate changes in blood pressure, body temperature, and alertness which varies depending on the time of day. Biological clock scientists help animals and humans feel when a day begins and ends.

The biological clock acts on the body, for example, when to eat, sleep and when burning calories, responding to the amount of light around animals, the biological clock may change according to slight changes. of light intensity . This means that when the biological clock is disturbed, people will eat and sleep abnormally. As a result, people eat and drink less physically, leading to obesity .

In a recent study, the mice were divided into three groups: One group was exposed to 16 hours in the light and eight hours in the dark each day. The second group lived in light for 16 hours, but used another 8 hours in dim light every day. The third group lives in 24 hours of bright light every day.

After a week of experiments, the researcher found that the group of mice that lived in dim light and bright light were gaining weight. After 8 weeks, the group of mice living in dim light and bright light weighed significantly more than mice in the first group.

But this is a surprise: The heavier mice did not eat more food, they only ate more than the first group of mice.

Mouse works naturally at night. That means they actively seek food at night. In the third group, rats ate almost all of their daily food intake. In the first group, mice eat only 1/3 of their daily food in the light. But mice belonging to the second group eat half of their food at the same time, when they see light.

The disruption of the biological clock in the night of the body and sending " eat now " signals to the brain at the wrong time . Rats may have been eating when their bodies were not prepared to digest and burn more food, according to scientist Richard Stevens, in the journal Science News. This miscommunication may be the cause of obesity.
