. Today's hot searches that drive countless night owls crazy.

"The harm of staying up late is not just about becoming ugly

1. Increase the risk of cancer

2007, World Health Organization (WHO) has defined "staying up late" as 2A carcinogenic factor . This is because the body's immune factor is mostly formed when sleeping, and staying up late for a long time will reduce immunity.

If there is obvious disorder in the circadian rhythm, it is very likely to accelerate the occurrence of diseases such as fatty liver, cirrhosis , hepatitis and liver cancer .

2, obesity

When sleeping, the human body secretes a substance called " leptin ". Long-term sleep disorder affects leptin secretion and is not conducive to fat decomposition.

3. The gastric mucosal epithelial cells of 3 people who damage the gastrointestinal tract are updated once every 2 to 3 days on average, and are usually performed at night. Eating meals during staying up late will cause the gastrointestinal tract to be rested and affect repair.

4, affect work and life

There is a natural physiological rhythm in the human body, keeping the human body and the outside world in synchronization day and night. When people do not follow the physiological rhythm, sleep late, stay up late, and stay up late, over time, cognitive damages such as memory loss, , inattention, and decreased creativity may occur.

5. Affecting emotions

People who stay up late for a long time are more likely to be irritable and irritable, and even the risk of depression will increase. *Some information source: Life Times

In addition, staying up late will also increase your risk of 2 diabetes and cardiovascular disease.

Just last week, researchers at Rutgers University in the United States published a study in the journal "Experimental Physiology" found that people who stay up late reduce their body's ability to use fat to obtain energy, resulting in fat accumulation, and those who stay up late are insulin resistant, increasing their risk of type 2 diabetes and cardiovascular disease [2].

No matter whether you are forced or voluntarily, irregular sleep caused by long-term sleep and staying up late will interfere with the normal synchronization of the human circadian rhythm such as light and temperature, causing the secretion of the endocrine system, nervous system, cognitive ability, emotional perception, and melatonin to fall into chaos.

Not only that, the biggest harm of staying up late in is affecting the normal operation of other organs.

Staying up late makes these organs suffer too

1, liver

clinical medical proves that excluding hepatitis virus infection factors, most liver diseases are closely related to staying up late.

The liver is the most important metabolic organ in our body. If liver cells are not repaired, the liver's metabolism and detoxification function will be greatly reduced, which affects the vitality of the entire body.

If the liver function does not get rest, it will cause relatively insufficient blood flow in the liver, making damaged liver cells difficult to repair and aggravate the deterioration.

In addition, if you already have fatty liver and continue to stay up late, it will also speed up the process of non-alcoholic steatohepatitis-hepatic fibrosis-hepatitis cancer.

2, kidney

3 At night, the kidney's filtration function is slower than during the day, and the urine will be reduced accordingly, so the color of the first urine in the morning is usually darker.

study found that long-term lack of sleep may cause kidney function to decline rapidly.

If you don’t sleep well at night, moisture will accumulate, resulting in early eyelids, feet, and legs swollen, and may also experience fatigue and inability to get up.

It is recommended to reduce the amount of salt, especially for dinner, and reduce the intake of high-protein foods.

drink at least 1200~1500 ml of water every day. Drinking one or two sips of water before going to bed can help the kidneys excrete, but don’t drink too much and avoid getting up at night frequently.

3, eyes

Staying up late is equivalent to overloading the eyes. Working hard in the light for a night can easily cause eye muscle fatigue. If this continues, it will lead to vision loss.

Some people who stay up late will also experience pain, dryness, swelling and other problems. In addition, they have low resistance, which can also induce eye diseases such as conjunctivitis , keratitis , and macular edema of the eyes.

Excessive use of the eyes can also cause poor blood circulation around the eyes, causing dark circles, bags or white eyeballs to be covered with bloodshot [3].

4, immune system

Our immune system is not always in the "on" state, it is also regulated by the circadian rhythm.

A study published in the journal Cell in July 2021 found that the body's ability to resist infection will rise and fall in the day. During the day, the body's ability to prevent food poisoning by producing a natural antibacterial molecule will increase; while has the weakest ability to resist infection at night [4].

So, while you stay up late and have midnight snacks, your immune system will not be with you, and in this case, your body is more susceptible to infection and problems.

5, brain

At night, the brain also needs to "get off work" and then do "cleaning".

In the human body, each organ will produce corresponding garbage and waste, and the brain is the most hardworking and active organ among them. Logically speaking, the most active organs should also excrete the most diligent, but other organs have lymphatic systems that excrete waste, but the brain does not.

The most effective way to clean the brain is to sleep! Only when sleeping can the brain use "cerebrospinal fluid" to clear all waste along the blood vessels, and there is no other way.

If you don’t pay attention to sleeping, you will really become stupid.

6, heart

people's normal heart rate is 60~100 times per minute. After falling asleep, the heart rate will slow down 10-30 times/minute less than when awake. At this time, the heart can relax.

. When you stay up late and stay up for 1 hour, your heart rate will increase by about 40%. This effect will last for at least 12 hours [5].

Why do many people find themselves panic, confused, and feel like they can't breathe after staying up late? Even the "sudden death" that is often heard in the news is because of heart problems.

The heart rate becomes faster, the blood flow of the heart will increase, the blood pressure will increase, and the heart rhythm will be abnormal.

Especially some people often stay up all night, but they also like to drink, smoke and eat midnight snacks. They always live on the road to "doing death". The heart is too burdened, and maybe one day they will be overwhelmed.

If you find yourself recently chest tightness, fast heartbeat, panic, upset , don't be careless, go to the hospital for examination earlier and don't stay up late.
