Is summer suitable for sports? What are the advantages or disadvantages?

Summer is very suitable for exercise, and people's appetite decreases in summer. If we insist on reasonable and effective exercise, we can not only improve the body's heat adaptability, but also increase energy consumption and make weight loss fruitful. My sports philosophy is to persist. Being thin is not necessary. Physical function, skin condition and positive emotions are the treasures of sports!

Benefits of summer exercise

1. In terms of exercise efficiency, hot weather in summer will increase the warm-up efficiency before training, and ensure that the body can be kept above a certain temperature during training, which will help improve training efficiency and reduce the risk of injury.

2. In summer, our body radiates heat faster, our metabolism level is higher, and the efficiency of burning fat during exercise is higher, which is a good time to lose weight!

3. In terms of physical fitness, the improvement of physical fitness will be strengthened every season throughout the year, and there will be obvious growth throughout the year. If you don't practice, your physical fitness will not improve in a quarter, but will decline, which will make slower progress than those who insist on exercising all year round. We are talking about people with similar constitutions.

The temperature is high in summer, so it is easy to feel sleepy and tired when studying and working indoors. If you have time to go to the gym to exercise and sweat, the whole person's mental state will be much better and the depression brought by work and life will be released. Moreover, this decompression method is very healthy, and long-term persistence can improve sub-health and enhance resistance.

Disadvantages of summer exercise

In fact, summer exercise, as long as it is not intense and excessive exercise at high temperature, will not do any harm.

Because you will sweat a lot when exercising in hot days, the blood volume of the human body will decrease, and the blood supply to important organs such as heart, brain and kidney will also decrease. When the human body sweats a lot, sodium ions, magnesium ions, calcium ions and potassium ions in body fluids will be lost in large quantities, thus causing arrhythmia.

When ventricular fibrillation occurs, Z is easy to induce the risk of cardiac arrest, especially for elderly patients with basic J disease such as hypertension, hyperlipidemia and coronary heart disease, and friends who like to play basketball and football at high temperature. Both high temperature and strenuous exercise will greatly increase the risk of cardiac arrest.

1, possibly dehydration and heatstroke.

The temperature is high in summer. If you exercise too much and sweat a lot, if you don't pay attention to replenish water, it will easily lead to dehydration symptoms, and in severe cases, you may suffer from heatstroke. You should stop exercising, replenish water as soon as possible, and move to a cool place to rest and recover.

2. Be alert to cardiovascular and cerebrovascular diseases

The influence of high temperature weather on human health is mainly heatstroke and death caused by cardiovascular and cerebrovascular diseases. Thermal radiation is long-term work or exercise in high temperature environment, which leads to vasodilation, congestion and fainting of lower limbs; For patients with hypertension and cardiovascular and cerebrovascular diseases, extreme heat will also lead to vasodilation and increased blood viscosity, which may easily lead to symptoms such as cerebral hemorrhage, cerebral infarction and myocardial infarction, and may even lead to death.

3. Exercise at high temperature may lead to sudden death.

Outdoor exercise in summer will increase the metabolism of human body, which will lead to an increase in heart load and easily lead to sudden cardiac death in summer.

Life lies in exercise, and exercise lies in persistence, so how to exercise safely in the sultry summer?

1, select the appropriate time.

It's usually hot in summer, so try to avoid noon and don't exercise in the scorching sun. It is best to exercise in the early morning or evening when the weather is cool, and you can choose indoor venues if you have the conditions.

2. Pay attention to the intensity of exercise

The weather is hot, and strenuous exercise is easy to get heatstroke. Therefore, the rule of summer exercise is to keep up and down rhythmic exercise, and soothing exercise has the best effect! No matter what kind of exercise, the amount of exercise should not be too large. Don't just persist after fatigue, take proper rest and adjustment at any time.

3. Scientific drinking water

In summer, human body water evaporates more, so drinking water is especially important for people who participate in fitness. Experts suggest that if you go out to exercise, it is best to bring your own water, drink a small amount of water constantly, don't wait until you are thirsty, and don't drink too much. Because overeating is very irritating to the stomach, and when drinking more than 1000 ml, it will cause diuresis through the body regulation mechanism, but it will cause water loss.

4. Avoid cold drinks during exercise.

Don't eat a lot of cold drinks immediately during or after exercise. Cold drinks not only reduce the temperature of the stomach, but also dilute the gastric juice, which damages the physiological function of the stomach, ranging from indigestion and diarrhea to acute gastritis.

5. Be wary of catching a cold.

Exercise at high temperature in summer, the body produces heat quickly, and the skin capillaries expand a lot, which is beneficial to the body's heat dissipation. If you encounter too cold stimulation, the pores that have been opened on the body surface will suddenly close, leading to dysfunction of internal organs of the body and abnormal temperature regulation of the brain, leading to illness, usually a "cold", that is, a summer cold.
