It is believed that many people like to sleep with the lights on, and many girls try various methods to lose weight. However, research has shown that sleeping with the lights on can also lead to weight gain, which has puzzled many girls. Why would they gain weight just by sleeping with the lights on? Does sleeping with the lights on actually cause weight gain?
Does sleeping with the lights on cause weight gain?
Long-term sleeping with the lights on may lead to obesity.
Sleeping with the lights on at night can affect sleep quality and hormone secretion, affecting the body's metabolism and potentially leading to weight gain.
Why does sleeping with the lights on cause weight gain?
1. There are two types of fat in the human body, brown fat and white fat. Brown fat is responsible for breaking down white fat, which can cause obesity, converting it into carbon dioxide, water, and heat, and does not store heat itself. White fat accumulates under the skin and is responsible for storing excess heat. Sleeping with the lights on at night can interfere with brown fat, leading to fat accumulation in the body and causing obesity.
2. Sleeping with the lights on at night may disrupt the circadian rhythm and affect the body's metabolism, increasing the risk of obesity.
3. Sleeping with the lights on can affect sleep quality, leading to insufficient sleep. Insufficient sleep can prevent insulin from properly metabolizing glucose in the body, potentially causing obesity.
4. Bright lights during sleep can also disrupt the secretion of two hormones: one is "satiety hormone," which makes people feel full and less likely to overeat; the other is "hunger hormone," which stimulates hunger and makes people seek food. Research has shown that lack of sleep can decrease levels of "satiety hormone" and increase levels of "hunger hormone," causing people to eat more and gain weight. This is also one of the reasons why sleeping with the lights on can cause weight gain.
What are the other drawbacks of sleeping with the lights on?
Long-term sleeping with the lights on can not only increase body weight but also affect sleep quality, suppress the secretion of melatonin, increase the risk of cancer, and cause significant damage to vision.
How to reduce the likelihood of weight gain from sleeping with the lights on?
Sleeping with the lights on is not a good habit, so try to avoid it as much as possible. If you must sleep with the lights on and don't want to risk weight gain, it is recommended to wear an eye mask or use a warm-colored night light instead of bright lights, such as a gentle red or orange night light.
