　　What not to do after exercise

　　It is not advisable to stop and rest immediately:

　　During strenuous exercise, blood is concentrated in the muscles of the limbs. Due to the strong contraction of the limb muscles, a large amount of venous blood will quickly return to the heart, and the heart will then send nutritious arterial blood to the whole body, resulting in extremely fast blood circulation. If you stop to rest immediately after strenuous exercise, a large amount of venous blood in the limbs will accumulate in the veins, and the heart will be ischemic. The brain will also suffer from hypoxic symptoms such as dizziness, nausea, vomiting, and shock due to insufficient blood supply to the heart.

　　It is not advisable to drink large amounts of water immediately:

　　If you drink too much water at one time due to thirst after strenuous exercise, the salt content in the blood will decrease. In hot weather, you sweat more, which makes it easier to lose salt and reduce cell osmotic pressure, leading to an imbalance in sodium metabolism and muscle cramps. Due to less gastrointestinal blood and poor function during strenuous exercise, the ability to absorb water is weak. Excess water seeps into the cells and intercellular substance.

　　Brain tissue is fixed in the hard skull. Swelling of brain cells can cause increased cerebral blood pressure, leading to symptoms of water intoxication such as headache, vomiting, drowsiness, blurred vision, and slow heartbeat. Drinking too much water at one time will cause an uncomfortable feeling of fullness in the gastrointestinal tract. If you lie down to rest, your cardiopulmonary activity will be affected by squeezing the diaphragm. Therefore, even if you are thirsty after strenuous exercise, you should not drink too much water at one time. You should use the method of "drinking less frequently" to drink water.

　　It is not advisable to take a cold shower, swim, blow dry or use air conditioning right away:

　　Some people want to feel happy for a while. As soon as the strenuous exercise is over, they immediately use an electric fan to blow on them, enter an air-conditioned room or enjoy the coolness in a cool vent. This will remove a lot of heat from the body, causing skin The temperature drops too fast, passing nerve Systemic reflex activity will cause vasoconstriction of the upper respiratory tract, slow down the swing of nasal cilia, and reduce local disease resistance. At this time, bacterial viruses parasitic in the respiratory tract will multiply in large numbers, which can easily cause colds, cold , tracheitis, etc. disease . Some people swim or take a cold bath immediately after strenuous exercise. Because the temperature of the limbs is very different from that of the water, calf cramps are also prone to occur.

　　It is not advisable to drink beer immediately:

　　After strenuous exercise, some people drink beer instead of water, which can easily cause a sharp increase in uric acid in the blood, leading to gout.

　　It is not advisable to eat immediately:

　　During strenuous exercise, because blood is mostly concentrated in the limb muscles and respiratory system, while the digestive organs have relatively less blood, their digestion and absorption capabilities are poor. After exercise, it takes a period of adjustment before the digestive function can gradually return to normal. Therefore, if you eat immediately after strenuous exercise, you will generally not enjoy the meal, and your ability to attract nutrients from the food will also be poor.
