What time does the body change day and night?


First of all, it must be said that staying up late will increase the risk of death. I believe everyone has heard that there are news that young people have died after sleeping for a night or night. Although staying up late is not directly related to sudden death, if your body still has long-term lack of exercise, obesity, high blood pressure, and mental or emotional depression, then a day or night is likely to become a crushing camel. The last straw caused sudden death.


At the same time, there are also many studies showing that people who sleep less than or equal to 5 hours at night have nearly twice the risk of death. It should be noted that the 5 hours here refers to nighttime sleep, which is not the time of daytime supplementation, so it is not enough to make up for sleep that is lacking in day and night.


Second, staying up late will increase the risk of heart disease and stroke. If the body stays up late for a long time, the burden of self-regulation of blood pressure and heart rate will be aggravated, and the regulation of vasoconstriction and immune function will gradually become abnormal. This will cause the heart to be prone to transient ischemia and also easily due to Coronary atherosclerosis and plaque instability cause myocardial infarction.


Again, staying up late does increase the risk of cancer. People who stay up late or have a long time difference, because the sleep cycle has been disordered, will cause their own immune function is low, such as people who stay up all night often have mouth ulcers, many people think it is just getting angry, in fact, this is the performance of low immunity.


The main function of our immune system is to monitor the cancer cells. Under normal normal conditions, the immune system can remove most of the abnormally differentiated cells in time, that is, timely discover cancer cells and inhibit cancer cell growth if we If the immune system is low and the function is damaged, the risk of cancer cells growing or suffering from tumors in the human body will increase greatly.


Finally, in addition to physical aspects, staying up late will have a lot of impact on people's psychological and spiritual aspects. I believe that most people are not willing to stay up all night, either work or study, or leisure. There is already a lot of pressure in work and study itself, and even for leisure and entertainment, we will warn ourselves in the subconscious to stay up all night, on the surface, to enjoy, in fact, the heart is still full of anxiety. Finally, we are still responsible for the deferred business due to leisure and entertainment, so as to face more pressure and anxiety.


When do you sleep late at night?


Having said so many nights and nights, many people may not know whether they are sleeping at the usual time. Judging whether you stay up late, one depends on whether you have slept for eight hours, and the other is whether there is a violation of the biological clock. For example, if you want to get up at 7 o'clock during the day, then sleeping after 11 o'clock the night before will stay up late. And if you want to sleep late, the normal human body clock will inevitably be affected, so try to close the cycle of work and the sun's light, which is the most suitable for human health.
