At this time, if you take a cold bath, the blood vessels will immediately contract due to sudden stimulation, the blood circulation resistance will increase, and the body's resistance will decrease at the same time, making people prone to illness. Taking a hot bath will continue to increase the blood flow in the skin. Too much blood will flow into the muscles and skin, resulting in insufficient blood supply to the heart and brain. In mild cases, it will cause dizziness, in severe cases, collapse and shock, and it can easily induce other chronic diseases. disease。

　　3. Can’t rest immediately

　　During strenuous exercise, the human heart beats faster, muscles and capillaries expand, and blood flow accelerates. At the same time, the rhythmic contraction of muscles squeezes small veins, causing blood to flow back to the heart quickly. If you stop to rest immediately at this time, the rhythmic contraction of the muscles will also stop, and the large amount of blood that originally flowed into the muscles will not flow back to the heart through muscle contraction, causing blood pressure to drop, causing temporary ischemia in the brain, causing palpitation, shortness of breath, dizziness, paleness, and even shock and fainting.

　　4. Don’t drink alcohol to relieve fatigue

　　After strenuous exercise, a person's body functions will be at a high level. Drinking alcohol at this time will cause the body to absorb alcohol components faster and enter the bloodstream, which will cause more harm to the liver, stomach and other organs than usual.
