It doesn't seem very serious?
Baidu searches for the keyword "staying up late, dying suddenly", and the news you see will make you turn off your browser instantly. So, is staying up late really the root of sudden death? The answer is no:
Staying up late is not the root of sudden death. Only those who show cardiovascular symptoms or have a family history of cardiovascular diseases are prone to sudden death. People with a family history of sudden death are at high risk of sudden death after staying up late. Guo Xiaoping, deputy chief physician of Shenzhen Emergency Center, pointed out that most white-collar workers who died suddenly suffered from basic heart disease or congenital malformation of cerebral vessels, but they were often discovered after autopsy.
That sounds great! For most people, staying up late is not the root cause of sudden death! So I can stay up all night freely?
Nice try!
Without the risk of cardiovascular disease, can people who claim to be in good health stay up late without stress? The answer is no, because staying up late will affect cardiovascular health and increase the risk of sudden cardiac death in the general population. An epidemiological study of 70,000 women aged 45-65 at Harvard University found that short sleep time is not conducive to heart health-compared with people who sleep for 8 hours a day, people who sleep less than 5 hours a day will have a 40% increase in the probability of heart disease. The reason is that short-term sleep deprivation is enough to make the sympathetic nervous system nervous, and lead to high blood pressure, increased secretion of stress hormones such as cortisol and adrenaline, decreased glucose tolerance and irregular heartbeat. All these factors are precursors of coronary heart disease. Long-term lack of sleep will promote the development of hypertension, obesity and diabetes, and diseases such as hypertension, obesity or metabolic syndrome are precisely the factors that induce heart attacks. In addition, lack of sleep will unbalance the human immune system, promote the level of inflammatory reaction of blood vessel wall, and promote the occurrence of atherosclerosis, thus increasing the risk of stroke.
It's too long, to help you sum up a sentence: staying up late will increase the probability of coronary heart disease and stroke. Think about these two diseases are desperate for life every minute, and dare to stay up late?
Besides, staying up late is really a killer for girls. During our sleep, we secrete various hormones, such as growth hormone, and the main hormone secreted during the prime time of sleep is growth hormone between 10 pm and 2am. It can repair damaged cells and promote the generation of new cells. Among the most important functions of growth hormone, a small part plays a cosmetic role in maintaining skin quality. Therefore, if you often stay up late, it will often have an impact on the period of massive secretion of growth hormone. After a period of time, the appearance is that the skin quality drops, and skin problems such as spots and acne appear. Therefore, if you don't stay up late and go to bed early, it is actually equivalent to wearing a new mask in the silent sleep at night.
To sum up, staying up late makes you ugly, and going to bed early makes you beautiful!
Also, the growth hormone mentioned above is also called "rejuvenation hormone" because it has the function of repairing damaged cells and promoting the generation of new cells. If you stay up late for a long time, insufficient secretion of growth hormone will also reduce immunity, leading to poor physical fitness and easy to get sick.
At the same time, growth hormone and cortisol can burn fat during sleep. If you stay up late for a long time, the secretion of these two hormones will be reduced, and it will also lead to unnecessary fat accumulation in the human body, which will cause obesity over time. ?
Isn't that enough? Heart disease, stroke, ugliness, decreased immunity, obesity ... So many dangers of staying up late, ask yourself, is it really worth it?
