"Don't sleep at night, can't get up in the morning" "Stay up late for a while, stay up late all the time" crematorium.
In this era of ever-increasing pace of work and life, "Be sure to go to bed early tonight!" "It's a flag that everyone has set up time and time again.
Some people stay up late because of work pressure, while others are caused by "procrastination". But whether active or passive, staying up late is not a good thing.
Listening to my mother's constant chanting "staying up late hurts the liver, staying up late becomes stupid, staying up late causes cancer", in fact, there is a certain reason.
So what are the dangers of staying up late for a long time?
Staying up late for a long time can lead to a disorder in the hormone levels in our body. Causes vasoconstriction and increased blood pressure. Even vasospasm. Causes angina.
How does it compare to people who sleep normally every day?
People who sleep for less than 6 hours for a long time are prone to hypertension, arteriosclerosis, coronary heart disease, stroke and other cardiovascular and cerebrovascular diseases are significantly increased.
People who often stay up late can also impair brain function.
(Memory loss, poor concentration, and slow reflexes.) ) increases the risk of Alzheimer's. It can even induce stroke. Sudden cardiac death is a life-threatening condition.
Therefore, we must not stay up late for a long time and overdraft our health. If you have to stay up late and work overtime, you should also adjust your work and rest time to supplement enough sleep in other times to greatly reduce the health risks caused by staying up late.
So we often say: sleep has a major benefit, because it can help the brain "detoxify".
A study published in the internationally renowned scientific journal Science found that cerebrospinal fluid can help the brain remove "toxic proteins" in the process of sleep. Staying up late will affect this "brainwashing" process (below), making it difficult to discharge harmful waste from the brain.
The process of "brainwashing"
When the elimination of toxic waste in the brain is blocked, the risk of Alzheimer's disease (that is, what people often call "Alzheimer's") also increases, and people will inevitably become more and more "stupid".
What's more frightening is that staying up late for a long time and irregular work and rest can really cause cancer!
Previously, scientists at the Massachusetts Institute of Technology in the United States did an experiment:
Artificially controlling the light in the living environment of mice, so that the mice continue to fall jet lag, it was found that the probability of lung cancer in mice who kept "staying up late" was significantly increased.

The same carcinogenic risk was observed in people who often stayed up late.
Some researchers have observed an increased risk of breast cancer among nurses who regularly work night shifts.
Coincidentally, the incidence of breast cancer has also increased among female flight attendants on international flights.
Other studies have found that people who sleep less than 6 hours per night have a 1.37-fold increased overall cancer risk and a 21% increased risk of lung cancer.
Based on growing evidence, in 2010, the International Agency for Research on Cancer (IARC) defined "shift/night shift" as a Class 2A carcinogen, that is, "likely to cause cancer".
In addition to cancer, staying up late can also lead to an increased risk of cardiovascular disease. This is due to the fact that when staying up late, the sympathetic nervous system is hyperfunctional, and the circadian rhythm of a series of hormones secretion changes.
People who slept less than 6 hours a day had a 32.4% increased risk of high blood pressure, an 11.1% increase in the incidence of various cardiovascular diseases, and a 45% increased risk of coronary heart disease within 10 years.
In addition, people who stayed up late were also at significantly higher risk of depression, sleep disturbances, and suicidal tendencies.
This night, you don't stay up.
After staying up late, how to "make up"?
If you don't stay up late often, you can make up for it.
Then you can do it in the following ways:
1. If you stayed up late the day before, you can take a nap for 20~30 minutes at noon the next day, at least to relieve the body from the tired state.
Relying on smoking, coffee or other "self-harm" methods to forcibly keep the body in a state of "excitement" will only bring more harm and is never desirable.
Many post-90s and post-00s are young, after the night shift or all-night play, it is not good to catch up on sleep, what to do the next day, it is really not recommended!
However, there is no sufficient research data as a reference for how much sleep needs to be made up, and it may depend more on personal experience. Some young people stay up all night, and the next day they sleep for two or three hours and are alive again; Some middle-aged people may stay up all night and sleep two or three hours more every day a week to recover their energy, and the individual differences are really big.
If you often don't get enough sleep, it will be difficult to recover your energy by catching up on sleep.
2. Try to quit smoking (stay away from secondhand smoke), do not drink, exercise regularly, and eat reasonably
Many people who stay up late are also exposed to other carcinogenic factors, such as smoking, alcoholism, inactivity, and unhealthy eating.
For example, people who like to stay up late on skewers, "stay up late + benzopyrene in the barbecue + tobacco + alcohol", plus "often like this", may lead to an organ can not withstand the pressure and become cancerous.
Remember these 4 things (no smoking, no drinking, regular exercise, reasonable diet) to at least make your body suffer a little less damage.
Stay up late, don't stay up if you don't stay up. When we are going to stay up late, we can consider whether what we are doing now is worth the cost of consuming our health!
Don't wait for yourself to get sick to know that health is really important!
