On March 17, Li Yuhuo, a professor at the National University of Singapore and an oriental scholar at Shanghai Maritime University, returned home after a run. According to her daughter, her father died because of coronary artery disease.
Why does a middle-aged professor who has always loved sports die suddenly after exercising?
Actually every year, sudden deaths occur in marathon races. In addition to the factor of strenuous exercise, Professor Li took a shower immediately after exercising, which was also an incentive for the tragedy.
Many people like to take a hot shower after strenuous exercise, thinking it will cleanse and reduce fatigue. Actually this is very harmful. After exercising, it is not recommended to take a shower immediately!
When a person is exercising, the blood flow to the muscles will increase and the heart rate will increase. When the exercise stops, the blood flow and the heart rate will ease, but it will continue for a long time. . If you go to take a bath at this time, the blood vessels of the skin will expand, which will increase the flow of blood to the skin and muscles. This situation will cause the remaining blood to be insufficient to supply other important organs, such as the heart and the brain, which may cause Induced cardiovascular and cerebrovascular diseases, severe angina, myocardial infarction, cerebral infarction, and even sudden death. And just after exercising, the breathing is not completely stable, because the bathing environment is small and the air is not circulating, the brain will be hypoxic, and people are prone to dizziness, general weakness, etc.
Post-workout tips:
1. The best suggestion is to take a warm bath 30 minutes after exercising. At this time, the human body has basically returned to its normal state, and the breathing and heartbeat are stable.
2. It is not advisable to use water with a particularly high temperature for bathing, because the body has lost water after exercise. Dazzling.
3. Try not to drink a lot of water immediately after exercise, which will not only increase the burden on the stomach, but also increase the burden on the heart due to a large amount of water entering the body, and even cause water intoxication and low sodium. A small amount of water is fine.
4. Don’t eat immediately after exercise, because most of the blood after exercise is in the skeletal muscle, and the stomach is relatively bloodless. If you eat immediately or eat too much, digestion will occur Bad, increase the burden on the stomach.
5. Do not stop and rest immediately after exercising, but do some soothing relaxation actions, which will help the blood of skeletal muscles to return to the heart and other important organs, otherwise the blood will stagnate in the lower limbs, and The inability to excrete metabolic wastes can lead to the accumulation of lactic acid.
6. Don’t take a cold shower after exercise, because the pores are open after exercise, and cold water will make the skin capillaries shrink violently, which is not only bad for heat dissipation, but also easily attacked by wind and cold, causing Cold and flu.
