Why is it easy to get heatstroke in hot weather?

Everyone knows the benefits of exercise, and the most important thing of exercise is perseverance, so many people don't stop the pace of exercise even in hot summer. However, the weather is extremely hot in summer, especially in the scorching sun or very high temperature environment. It is very easy to get heatstroke by insisting on exercise. So why is it easy to get heatstroke in hot weather?

This is because if you exercise vigorously at high temperature for a long time, on the one hand, your body sweats a lot, and in a short time, your body loses a lot of salt and electrolyte, which affects the balance of body fluids and metabolism. More importantly, when you are exercising vigorously, the human body will generate a lot of heat, and the temperature of the surrounding environment is relatively high, so it is difficult for people's body heat to spread to the outside world. The direct consequence of this is that the body temperature will be as high as 40 degrees Celsius. Because human brain cells can't bear the high temperature, it is easy to have the dysfunction of the central nervous system such as cerebral cortical cells, and the symptoms of brain tissue congestion and edema appear. At this time, most of them will have dizziness, dizziness, palpitation, asthma and other symptoms.

After heatstroke, because the body temperature of heatstroke patients may be as high as 40 degrees Celsius or above, physical cooling method should be adopted to reduce the body temperature to normal level as much as possible. The general treatment method is to move the heatstroke victim to a cool and ventilated place, loosen the patient's buttons and belts, let him rest quietly, and pay attention to others not to watch and make noise; Patients with heatstroke can be given salty boiled water (lukewarm), or herbal tea to relieve summer heat, or blown by an electric fan. If necessary, you can cover it with ice or bathe in alcohol.

Some patients will have complications after heatstroke. At this time, you should immediately send it to the hospital for symptomatic treatment to prevent the condition from getting worse.
