Don't take a cold bath when sweating (or swimming). When sweating after exercise, the capillaries on the body surface expand and a lot of heat is released in the body. At this time, if you encounter cold water, the capillaries will suddenly contract, which will easily reduce the body's resistance and cause diseases.
Don't "omit" finishing activities. When you feel exhausted after each exercise, you should relax appropriately, such as unarmed exercise, walking and relaxing massage. It helps to eliminate muscle fatigue and restore physical strength quickly.
If you don't eat right away, eating right away without rest after exercise is easy to cause disorder and dysfunction of the digestive system of the human body, and it is easy to get sick.
A sudden drop in body temperature is not desirable. The sudden drop of body temperature will break the normal physiological regulation function, make the physiological function out of balance, and easily get diseases such as cold, diarrhea, asthma, wind-cold joint pain.
It is not advisable to take a hot bath immediately. After exercise, a lot of blood in the body is distributed on the limbs and body surface. If you take a hot bath at this time, it will increase the blood flow on the body surface, resulting in insufficient blood supply to the heart and brain, and there is a risk of cardiovascular and cerebrovascular accidents.
