What are the dangers of staying up late? Skin damage, decreased immunity and memory

Staying up late seems to have become commonplace for modern people. Even if they don’t need to work overtime, they still have a rich nightlife. After staying up late, you will feel tired and skin problems will follow, which will cause the body's metabolic rate to drop significantly, which is not worth the loss. So what are the dangers of staying up late?

The skin enters its night maintenance state between 10pm and 11pm. If you stay up late for a long time, the normal circulation of your endocrine and nervous system will be disrupted. Nervous system disorders can cause your skin to become dry, inelastic, dull, and lack luster; while endocrine disorders can make the skin, especially the skin of young people, prone to problems such as acne, blackheads, chloasma, and dark spots.

Disadvantage 2: Obesity

Any meal eaten after 20:00 p.m. is called "midnight snack". There are two types of autonomic nervous system in the human body: sympathetic nervous system and parasympathetic nervous system. The sympathetic nervous system makes the stomach work more frequently during the day when the body is active, promoting digestion and absorption; at night, the parasympathetic nervous system is active, allowing the body to rest while the nutrients taken in are stored in the body. Eating at night will not only make it difficult to fall asleep, but also cause loss of appetite the next morning. The resulting nutritional imbalance will cause obesity.

Disadvantage 3: Decreased immunity

If you often stay up late, feel tired, and lack energy, your body's immunity will decline, and symptoms of autonomic nervous system disorders such as colds, gastrointestinal infections, and allergies will come to you unexpectedly. Moreover, the direct symptoms of staying up late frequently are dizziness, inability to concentrate, and even migraines at work the next day.

Disadvantage 4: Memory loss

Normally, a person's sympathetic nerves should rest at night and be active during the day to support a person's work and life throughout the day. However, the sympathetic nerves of people who stay up late are excited at night, so they will experience lack of energy, dizziness, memory loss, inattention, slow reaction, forgetfulness, dizziness, headaches and other problems during the day. Over time, problems such as neurasthenia and insomnia may occur.

Disadvantage 5: Deafness

Some people play online games all night long, go to bars and discos, and play mahjong without restraint, resulting in many people suffering from severe sleep deprivation. Lack of sleep can easily put blood vessels in a state of tension, resulting in insufficient blood supply to the inner ear, which is extremely damaging to hearing. Staying up late for a long time may lead to deafness.

Disadvantage 6: Risk of heart disease

It is not as easy as most people think for people with irregular work and rest schedules to adjust their bodies. Not only will their tempers become worse, but their chances of developing heart disease are also higher. Because the human body's biological clock is not affected by light or clocks. Especially organs like the heart will not be able to adjust to staying up late just because they rest during the day. Therefore, if you "reverse day and night" for a long time, it will increase the risk of heart disease.

Disadvantage 7: Gastrointestinal crisis

People who stay up late easily feel tired, and eating "midnight snacks" can be a major source of energy for them. However, "midnight snacks" may pose a risk to the stomach, which makes people worry, because eating late-night snacks frequently can easily cause stomach cancer. The life span of human gastric mucosal epithelial cells is very short, and they need to be renewed and regenerated every 2 to 3 days on average. This process usually takes place at night when the gastrointestinal tract is resting. If you often eat at night, the gastrointestinal tract will not get the necessary rest and the repair of the gastric mucosa will not be able to proceed smoothly. Moreover, when sleeping at night, the midnight snack stays in the stomach for a long time, which can promote the secretion of a large amount of gastric juice and cause irritation to the gastric mucosa. Over time, it can easily lead to erosion and ulcers of the gastric mucosa.
