Sleeping with the television on or with a light in the room can make you gain weight or develop obesity, especially if you are a woman.
This is explained by a study National Institutes of Healthaccording to which exposure to artificial light during sleep causes weight gain in women.
The study and its results on how sleeping with the light on could make you gain weight
The scientists used the answers obtained from the “Sister Study” questionnaire, carried out on 43,722 women, in which the participants were asked if they slept with or without light. By comparing the answers with data such as weight, height or body measurements, a follow-up study was carried out for five years. The results revealed that the weight of the women changed depending on the level of artificial light to which they were exposed during sleep.
A small light at night produced no change in weight, while an artificial light or TV turned on increased by a 17% chance of gaining 5 kilos or more in 5 years. However, when the light came from outside, the weight gain was less.
Humans -explained Chandra Jackson, co-author of the study- are genetically adapted to a natural environment made up of sunlight during the day and darkness at night. Exposure to artificial light at night can disrupt hormones and other biological processesincreasing the risk of health disorders such as obesity.
TV on is a bad habit even during meals
Artificial light from the television often accompanies our meals. But as Luca Piretta, nutritionist at Manzana Roja, explains to us, eating in front of the TV is always A bad habit that should be lost. This is because the screen distracts us from what we are doing and, above all, from what we are eating. And the lack of attention we pay to food affects our satisfaction and feeling of satiety.
