On March 17, Li Yuhuo, a professor at the National University of Singapore and an orientalist at Shanghai Maritime University, returned home after a run, felt unwell after taking a shower, and fainted on the way to the hospital, at the age of 53. According to her daughter, her father died of coronary artery disease.
Why does a middle-aged professor who has always loved sports die suddenly after exercise?
In fact, sudden deaths on the marathon field occur from time to time every year. In addition to strenuous exercise, Professor Li took a shower immediately after exercise, which was also a cause of tragedy.
Many people like to take a hot bath after strenuous exercise, thinking that this will both decontaminate and eliminate fatigue. In fact, this is very harmful. After exercise, it is not recommended to go to the bath immediately!
When people exercise, the blood flowing to the muscles will increase, the heart rate will increase, and when the exercise stops, the blood flow and heart rate will be relieved, but it will still last for a long time. If you go to the bath at this time, the skin blood vessels dilate, it will increase the flow of blood to the skin and muscles, which will lead to insufficient blood to supply other important organs, such as the heart and brain, which may induce cardiovascular and cerebrovascular diseases, and in severe cases, angina, myocardial infarction, cerebral infarction, and even sudden death. And just finished exercising, breathing has not been completely stable, will be because the bathing environment is small, the air does not circulate, the brain will appear hypoxia, people are prone to dizziness, general weakness and so on.
A few big suggestions after exercise:
1. The best recommendation is to take a bath 30 minutes after the end of exercise and take a warm bath, at this time the human body has basically returned to a normal state, and the breathing and heartbeat are stable.
2. It is not advisable to use water with a particularly high water temperature to bathe, because the body has lost water after exercise, if you bathe with high temperature water again, it will lead to more loss of water in the body, which is easy to cause prostration, dizziness, and dizziness.
3. Try not to drink a lot of water immediately after exercise, not only will increase the burden on the stomach, but also because a large amount of water enters the body, increasing the burden on the heart, and even water intoxication and low sodium phenomenon, a small amount of water is OK.
4. Do not eat immediately after exercise, because most of the blood after exercise is in skeletal muscle, the stomach is relatively lack of blood, if you eat immediately, or eat too much, there will be indigestion and increase the burden on the stomach.
5. Do not stop and rest immediately after exercise, do some soothing relaxation actions, which is conducive to the return of skeletal muscle blood to the heart and other important organs, otherwise the blood will be stasis in the lower limbs, and the metabolic waste cannot be discharged will cause lactic acid accumulation.
6. After exercise, you can not take a cold bath, because the pores are in an open state after exercise, and the cold water will make the capillaries of the skin contract violently, which is not only not conducive to heat dissipation, but also easy to be attacked by wind and cold, causing colds and colds.
