Everyone knows that staying up late hurts your health, but when do you sleep? From the point of view of endocrine and biological rhythm, sleeping after 23 o'clock counts as staying up late. Since most self-repair activities are carried out before 3 am, the quality of sleep between 23 am and 3 am is particularly critical. After this period of time, it is difficult to make up for the losses caused by staying up late, even if it takes a long time to catch up on sleep.
A study published in the American Journal of Neurology, targeting 500,000 people and following up for 10 years, found that staying up late is an independent risk factor for cardiovascular disease. Adults who wake up early, have difficulty falling asleep or maintaining sleep, and feel sleepy at least three days a week have a risk of cardiovascular disease of 7%, 9% and 13% respectively. Researchers from Massachusetts General Hospital and Harvard Medical School have reached the same conclusion in experiments on mice. Mice with long-term sleep fragmentation (sleep interruption or lack) are more prone to anxiety, produce more inflammatory cells and form larger atherosclerotic plaques. It is suggested that teenagers in growth and development should sleep 8~ 10 hours every night; People aged 30-60 should sleep for 6-7.5 hours every night to ensure adequate rest and energy during the day; After 60, I have to sleep for 6 hours at night.
It can be seen that the female doctor's immunity has declined because of staying up late and working overtime for a long time. I would like to remind everyone here that staying up late should be moderate and working should be moderate. Health is the most important!
