Insomnia and staying up late have become the norm for contemporary people. However, such habits are very unhealthy. Staying up late frequently can slow down the body's metabolism, leading to obesity. So what are the dangers of staying up late for a long time?
Why does staying up late make people gain weight?
1. Poor sleep leads to increased eating
Staying up late can increase the level of growth hormone in the body, which stimulates appetite and increases food intake.
At the same time, it can decrease the level of leptin, which is responsible for suppressing hunger and increasing metabolic rate. Therefore, people who stay up late often feel hungry and eat more, leading to weight gain over time.
2. Insufficient sleep leads to decreased metabolism
Staying up late can disrupt our biological clock and affect metabolism. Sleep is a key factor in replenishing energy and regulating metabolism throughout the day. If we have insufficient sleep or cannot enter deep sleep, our metabolic rate will slow down.
Correspondingly, the metabolism of breaking down and burning fat will also slow down. As a result, a large amount of fat that should be burned during sleep will accumulate in the hips, abdomen, and legs. No matter how much energy we consume during the day, it cannot compensate for the valuable time of fat burning lost at night.
The dangers of long-term staying up late
1. Skin
The skin typically enters a maintenance state around 10-11 pm. If you stay up late for a long time, your endocrine and nervous systems will become imbalanced, resulting in dry, dull, and acne-prone skin, as well as blackheads and dark spots.
2. Brain
Staying up late keeps the sympathetic nervous system excited at night, leading to fatigue, dizziness, memory loss, lack of concentration, and slow reaction during the day.
3. Vision
Overloading the eyes for a long time can cause eye pain, dryness, and swelling, and even lead to dry eye syndrome. Eye muscle fatigue can also cause temporary vision loss.
How to avoid gaining weight from staying up late?
1. Go to bed early and wake up early, and avoid staying up late
In our daily lives, we should learn to go to bed early and wake up early. This not only helps the body burn fat but also prevents gastrointestinal overload. It also helps prevent constipation and eliminate foul-smelling stool.
2. Avoid eating snacks frequently
Snacks not only contain a large amount of fat and carbohydrates but also have high levels of sugar and sodium, which are the main causes of obesity. Therefore, it is helpful to eat fewer snacks in order to lose weight and maintain the health of the body and blood sugar.
3. Eat more fruits regularly
Eating more fruits can not only suppress appetite but also help with bowel movements. We can replace staple foods with fruits during dinner, which can not only reduce calorie intake but also promote gastrointestinal peristalsis, thus relieving constipation.
