According to a recently published study, people who sleep in front their TV may be more at risk of obesity and weight gain than the general public. The American researchers behind the research believe that there is an important link between falling asleep in front of a television and obesity as well as weight gain in general. The study was conducted on tens of thousands of women.
A study conducted in 2015 had concluded that spending too much time watching television in youth affected the brain in middle age. Now, a study conducted by the National Institutes of Health in the United States and published in the journal Jama Internal Medicine on June 10, 2019 found that light emanating from television can be equally harmful to our weight.
The study was conducted over 5 years and involved 43,722 women aged 35 to 74 years. However, some of them had the bad habit of falling asleep in front of the television or in the presence of a strong artificial light. According to the results, the women who participated in the research took an average of 5 kg during this period.
The researchers concluded that exposure to artificial light before and during sleep had a strong link with weight gain, and therefore with the risks of overweight and obesity. Leaders of the study nonetheless indicated that further research was needed to clarify this link. It is also questionable whether reducing exposure to artificial light at night could prevent the risk of weight gain. Moreover, the study only concerns women, so that it is impossible to mention the case of men.
A quality sleep is necessary for a healthy life. It’s already known that a lack of sleep favored weight gain. It is a question of a metabolic modification in a negative way, reinforcing the capacity of the body to store fat. In addition, it has also been proven that exposure to artificial light from screens before falling asleep inhibits a person’s ability to fall asleep. People are encouraged to turn off their smartphone one hour before getting ready to sleep. Indeed, the blue light generated by this type of screen is an endocrine disruptor and impairs the user’s ability to sleep.
