Here are some common sense or suggestions for sports:
Physical exercise can enhance physical fitness and prevent many diseases, which can be described as beneficial and harmless. But it is worth noting that we should pay attention to the correct way of rest after exercise. If you don't squat and rest immediately after fitness exercise, it will hinder the blood circulation of lower limbs, affect blood circulation and deepen physical fatigue. This kind of situation is more common in those activities with relatively large amount of exercise, such as long-distance running. The correct way is to do more relaxation activities after each exercise, such as walking slowly and relaxing your legs.
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" the closing 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 cold drinks, you will reduce a lot of calories when you exercise. It is understandable that you need to supplement urgently. However, after exercise, the human digestive system is still in a state of inhibition, and eating a lot of cold drinks is easy to cause gastrointestinal diseases such as gastrointestinal spasm, diarrhea and vomiting.
If you don't eat immediately, the whole body blood will be redistributed during exercise, which will weaken gastrointestinal peristalsis and greatly reduce the secretion of various digestive glands. If you eat immediately after exercise without rest, it will easily lead to the disorder and dysfunction of the digestive system of the human body, and it is easy to get sick.
People breathe faster when they don't smoke, and their bodies should ensure adequate oxygen intake. If you smoke immediately after exercise, the oxygen content in your lungs will decrease, resulting in chest tightness, asthma, dyspnea, dizziness, fatigue and other symptoms.
A sudden drop in body temperature is not desirable. If the outdoor temperature is high, you will feel very hot and unbearable after exercise. If you go into the air-conditioned room or take a cold nap at this time, it will break the normal physiological regulation function, make your physiological function out of balance, and easily get diseases such as colds, diarrhea, asthma, cold and 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.
