Some tips on physical exercise

As our awareness of health care gradually increases, doing moderate exercise every day has become an important part of many people's daily life. Exercise can not only help us improve our immunity, but also promote blood circulation and help the body sweat and detoxify. It is a very beneficial exercise for physical and mental health. Today I will introduce to you some common knowledge about physical exercise, let’s take a look.

one. It is not advisable to squat and rest immediately: If you squat and rest immediately after fitness exercise, it will hinder the blood return to the lower limbs, affect blood circulation, and deepen body fatigue. During strenuous exercise, blood is mostly concentrated in the limb muscles. Due to the strong contraction of the limb muscles, a large amount of venous blood will quickly flow back to the heart. The heart then sends the nutritious arterial blood to the whole body, and the blood circulation is extremely fast. If you stop to rest right after strenuous exercise, a large amount of venous blood in the limbs will accumulate in the veins, the heart will be deprived of blood, and the brain will experience symptoms such as dizziness, nausea, vomiting, and shock due to insufficient blood supply and lack of oxygen.

two. Do not take hot or cold baths (or swim) when you are sweating profusely: When you sweat profusely after exercise, the capillaries on the surface of the body expand and a large amount of heat is dissipated from the body. If you encounter cold water at this time, your capillaries will suddenly contract, which can easily reduce the body's resistance and cause illness. If you take a hot bath immediately at this time, it will increase the blood flow to the body's surface, causing insufficient blood supply to the heart and brain, and there is a risk of cardiovascular and cerebrovascular accidents.

three. Do not "omit" finishing activities: When you feel exhausted after each exercise, you should relax appropriately, such as doing calisthenics, walking, relaxing massage, etc., which will help eliminate muscle fatigue and quickly restore physical strength.

The above content introduces some common sense about physical exercise in great detail. I hope it can serve as a reference for more friends. From this we can see that exercising also requires certain methods and approaches. Resting or taking a cold shower immediately after exercise is very bad for blood circulation. The correct approach is to do some small movements after exercise.
