They always feel that they are young and the disease is far away from them, and they live their lives with a fluke, and even take staying up late as a habit, but with more and more young people having brain hemorrhage now, it also rings an alarm bell for them, and many young people will ask, will staying up late for a long time really lead to brain hemorrhage? First of all, staying up late for a long time is certainly not good for people’s cerebral blood vessels, because people have a physiological cycle, the daytime adrenaline secretion is high, there is sympathetic excitement, such people are nervous or more vitality, at night, adrenaline secretion will be reduced, people will become calm, if you stay up late at this time, the sympathetic system is still highly excited, adrenaline in secretion, it will make many small blood vessels In the contraction, blood pressure is increased, long-term past will make some small blood vessel wall thickening, and finally lead to hypertension, hypertension and further make the blood vessels become narrow or weak, weak places may bleed, so staying up late will lead to brain hemorrhage. And stay up late for a long time is actually overspending their bodies, we sleep at night is to let our bodies rest and relax, metabolism and detoxification, if you can not sleep at the appropriate time, it will damage our health, and even cause irreversible consequences, we should avoid staying up late often, to ensure adequate sleep, proper exercise, take care of our bodies.
