It is a good thing to participate in the movement, but the unwavering of some small details may cause physical injuries and even more serious consequences. Do not take it lightly.

Why not drink cold drinks right away?

Summer weather is hot, especially after strenuous exercise outdoors, drinking cold drinks is the unanimous choice of everyone. However, it is extremely risky. Experts explain that when the temperature is high, the human blood vessels are expanding. If you drink a large amount of cold drinks immediately after severe exercise, it may cause the whole body to shrink and spasm immediately, the blood pressure suddenly increases, the blood viscosity increases, and the coagulation will occur. Card the blood vessels, which may induce angina pectoris and myocardial infarction.

In addition, drinking a whole bottle of cold drink is too fast, which will not only cause irritation to the heart, but also cause irritation to the stomach and intestines. disease.

The doctor suggested that if the athlete really wants to drink cold drinks, it is best to drink cold drinks after the heart rate is relatively stable after 3 minutes to 5 minutes. Or put cold drinks in your hand or hot place to warm up for one or two minutes, and you should drink it slowly.

Why not drink a lot?

People evaporate a large amount of sweat during exercise, and they often feel dry mouths after exercise. After the exercise, people can't wait to drink water immediately to relieve their thirst. But drinking a lot of water is not good.

This is because after strenuous exercise, a large amount of sweats cause more salt consumption in the body. Drinking a large amount of water can not replenish salt. Instead, the sodium concentration of the blood will be reduced, which may cause hyponatremia. Low sodium ledmia can cause bloating or nausea in exercise. In severe cases, it may also cause cerebral epilepsy and death. In addition, the body is still in excitement after exercise, and the heartbeat speed does not recover slowly in time. If a large amount of water is drinking at this moment, the circulation flow of blood will increase, the heart burden will suddenly increase, and it will cause cardiopulmonary function abnormalities.

When will I drink water after exercise? This must be determined according to the intensity of exercise. If the amount of exercise is not large, you can drink water after about five minutes, but you cannot drink water immediately after strenuous exercise. After a while, you can wait for a while. Then replenish it in an appropriate amount. In the case of severe thirst after exercise, the correct way to drink water should be taken to relieve the thirst. You can first rinse your mouth and moisturize your mouth, and then use a small amount. After a large amount of sweating, you also need to add salt while replenishing the water. You can drink some drinks or light salt water that supplement the electrolyte.

Why not rest immediately?

This is a very common approach. After the exercise, I feel tired after the exercise. I squat or sit down and think that it can save effort and rest. In fact, this is also a wrong approach. If you squat down immediately after the severe exercise, it will hinder the flow of blood from the lower limbs, affect the blood circulation, and deepen your body fatigue. Severe gravity shock is generated.

This is because during exercise, the blood supply to the human lower limbs requires a sharp increase in volume. At the same time, a large amount of blood needs to return a large amount of blood from the lower limbs to the heart. If the static removal of static after the severe exercise, the blood stasis of the lower limbs will not be returned in time. The blood volume of the heart is insufficient, and the discharge will be reduced. Therefore, the above series of symptoms will occur. Therefore, after strenuous exercise, you should continue to do some slow organizing and relaxing activities.

Why not take a bath immediately?

After exercise, some people rushed from head to toe to take a cold bath for the sake of pain. At that time, they felt very happy, but they might feel weak afterwards. Studies have found that after the severe exercise, the generations of their lives are constant to maintain the body temperature, the surface of the skin surface is expanding, the pores are large, and the sweat is increased to facilitate heat dissipation. At this time Sweating and heat dissipation are blocked, the heart burden worsen, and the body's resistance is reduced, and people are susceptible to illness.

So, is it okay to take a hot bath? the answer is negative. If the hot bath, it will continue to increase the blood flow in the skin, and the blood flows too much into the skin and muscles, which will cause insufficient blood supply to the heart and the brain. Essence Therefore, after strenuous exercise, dry sweat should be wiped first, drinking some salt boiling water properly, and when sweat no longer comes out, it is more appropriate to take a warm water bath. The water temperature should not be too high, and it is generally suitable for 35-40 ° C.

Why not blow the air conditioner immediately?

After exercise, in order to cool the body, some people like to blow their bodies directly at air conditioners or fans. In fact, doing so is also very unfavorable to the body. As soon as the exercise ended, the human body was still in the condition of strong metabolism, increased heat production, and expansion of skin vascular expansion. At this time, if the air conditioner is blown immediately, the body enters the cold environment from the hot environment, and it is too late to adapt to adjustment. It is often prone to cold or cause gastrointestinal spasm. After exercise, muscle fatigue and tension are increased. At this time, cold stimulation may also cause cramps. The correct practice should be about half an hour after the exercise is ended, and then enter the air -conditioned room after the body is cooled.

Why not eat immediately?

Many young people will choose to "rub a meal" near the ball.

However, experts remind that during intense exercise, the motor nerve center is in a highly excited state. Under its influence, managing the side -sensing nervous system of the internal organs' organ activity has strengthened the suppression of the digestive system activity. At the same time, during exercise, the blood of the whole body is also re -assigned, and the needs of the sports organs are more concentrated, and the supply of various organs in the abdominal cavity is relatively reduced. These factors weaken the peristalsis of the gastrointestinal tract, and the secretion of various digestive glands is greatly reduced.

It requires 20 minutes to 30 minutes to recover. If you eat in a hurry, it will increase the burden on the digestive organs, cause dysfunction, and even cause a variety of diseases.

Hot days exercise, beware of "thermal irritation"

Summer and high temperature, people often say "hot and dead." But many people who like fitness think summer is a good season for fitness. In order to pursue the "sweating" exercise effect, some people have the most special temperature and the most sunlight when they are the most temperature -free.

According to the severity of the disease, heat stroke can be divided into three types, including threatened heat stroke, mild heat stroke and severe heat stroke. Thermal radiation disease is severe heat stroke and is the most dangerous and serious heat stroke. According to the online version of the "PLA Medical Journal" in 2019, "The Consensus of the Diagnosis and Treatment Expert in China", thermal injection is a serious fatal disease caused by thermal damage to the body. The body's heat production and heat dissipation imbalance caused by the severe exercise. The typical symptom is the core temperature of the core. Some doctors said that the mortality rate of thermal irritation can reach 70%-80%.

High temperature itself is the induction of sudden death, and should try to avoid strenuous exercise under high temperature conditions. If you ca n’t avoid it, you should pay attention to replenishing water and electrolytes. A small amount of light salt water with a small amount of normal temperature, at the same time pay attention to ventilation, and minimize the body temperature.

Finally, remind everyone that physical exercise must follow the human body's physiological function.

Summer sports tips

Scientific hydration must be kept in mind

In summer, in addition to replenishing moisture and electrolytes in time, remember to supplement the appropriate amount of sugar, which can help relieve exercise fatigue and prevent muscle spasm and heat stroke.

Reasonable cooling is a trick

Summer exercise can choose different measures to cool down, such as wearing cooling clothing (breathable vests), wearing a cooling cap. In addition, the head and neck can be sprinkled with normal warm water to effectively cool down.
