5 items of “Summer Training”
It is now in the three days, the hottest season of the year. Its climate is characterized by high temperature, low air pressure, high humidity and small wind speed. Such climatic conditions have obvious adverse effects on human health.
Studies have shown that when the ambient temperature reaches 33 掳 C, people will sweat in a quiet state, but still maintain the balance between heat production and heat dissipation.
If physical activity is carried out at this time, the amount of sweat will increase greatly, and the higher air humidity and lower wind speed will make the sweat evaporation not fast, the body heat dissipation will be difficult, the body temperature regulation will be limited, and the heat will be accumulated.In the body, it may cause symptoms of heatstroke such as body heat, dizziness, thirst, and nausea.
In addition, high temperature causes excessive loss of salt in the human body, imbalance of water and salt metabolism, which causes obstacles in blood circulation, and there are “hot sputum” (such as “heatstroke”) such as muscle spasm, decreased urine output, and accelerated pulse.
Therefore, the summer and the three should pay attention to the following aspects:
It is not appropriate to exercise in the summer. It is generally required to exercise in the hot sun. Generally, it should be placed in the morning or evening, and choose a cool and ventilated place.
Indoor sports venues should have good ventilation and cooling equipment.
When the gas consumption is relatively high on a hot day, the amount and intensity of exercise can be appropriately reduced.
When the temperature exceeds 35 掳 C, it is best to stop all activities to static braking.
Different from person to person The function of the elderly is diminished, and the body water is about 15% less than that of young people. Therefore, the heat resistance is far lower than that of young people. The probability of heatstroke in the elderly is also higher than that of young people.
In addition, the blood concentration of the elderly is inherently high, and the cardiovascular and cerebrovascular diseases are also high. In the hot weather, the body fluid and blood in the body will be significantly reduced, the blood concentration will be further increased, and the blood viscosity will rise.High, it is more likely to induce severe symptoms such as cerebral thrombosis and myocardial infarction.
In this sense, the elderly should be cautious in the summer.
Make up the water In summer, exercise, because of a lot of sweat, lose a lot of water and salt, it is easy to cause enthusiasm.
If you drink a small amount of refreshing summer drinks and low-sugar salty drinks at rest, you can not only reduce the salt that is reduced by sweating in the body, but also limit some water from being discharged in large quantities.
However, it should be noted that after strenuous exercise, it is not advisable to eat cold food such as popsicles to avoid gastrointestinal dysfunction, causing abdominal pain and diarrhea.
Reasonable diet After exercise, it consumes a lot of physical strength and energy. At this time, it is necessary to supplement the nutrition in time. The diet should pay attention to eating more digestible food.
Because of the heat of the day, sweating, drinking more, stomach acid is diluted, digestive juice secretion is reduced; should eat more foods that are soaking in water; should eat more bitter and sour food, bitterness such as bitter gourd, can clear the heat and spleen, increase appetite,Sour taste like tomato, can thirst, stomach and digestion.
Eat less cold food, eat less cold drinks, especially ice, so as not to cause abdominal pain and other symptoms.

At the same time, there are some routine heatstroke prevention drugs such as human Dan, ten drops of water, cool oil, and Huoxiang Zhengqi water.
