Can people really die of heat? What diseases can be induced by long-term exposure to high temperature?

1. People will really die of heat. Heatstroke is an acute disease characterized by central nervous system and/or cardiovascular dysfunction, which occurs in high temperature or high humidity and closed environment. Due to the dysfunction of the central nervous system or sweat glands, too much water and electrolyte are lost. When you go out at noon, you can take an umbrella to avoid direct sunlight and play a certain protective role; It's hot and sweaty, so be sure to drink more water. Once the symptoms of heatstroke such as dizziness, chest tightness, palpitation and even syncope appear, the patient should be quickly removed from the high temperature environment, physically cooled and supplemented with normal saline. If the condition is serious, the patient should be sent to the hospital quickly.

2. Solar dermatitis, under the action of ultraviolet rays, the epidermal cells of the skin are destroyed, protein degenerates and decomposes, capillaries dilate and congestion, and skin erythema appears in exposed parts such as face, neck and back of hand, which leads to solar dermatitis. Besides erythema, there are scales and blisters, accompanied by itching or pain.

3. Psychological heatstroke, high temperature weather easily affects the emotional regulation center of human hypothalamus, which is mainly manifested as upset, disordered thinking and temper tantrums. This belongs to "psychological heatstroke", which is medically called summer affective disorder. Medical experts suggest that in the sultry summer weather, we should maintain a good attitude and develop healthy living habits: stay up late and drink plenty of water; Don't drink a lot of cold drinks when you are extremely hot and thirsty; Don't turn on the air conditioner immediately when you return to the room from the outdoor high temperature. Wait until the sweat is absorbed, and keep the air conditioner temperature above 26 degrees Celsius.

4. Cardiovascular diseases, for people with hypertension, cardiovascular and cerebrovascular diseases, in the windless, low-pressure, high-temperature and humid environment, human perspiration is inhibited, heat storage in the body increases, and myocardial oxygen consumption increases, making the cardiovascular system in a state of tension. The sweltering heat can also lead to vasodilation and increased blood viscosity, which is more likely to lead to symptoms such as cerebral hemorrhage, cerebral infarction and myocardial infarction, and even death in severe cases. Research shows that the incidence of cardiovascular diseases will increase by about 65438 0℃ every time the temperature rises in summer. High temperature in summer is more important for the elderly with cardiovascular diseases. They should keep up with the season, stay up late and get up early, and take a nap at noon. At the same time, you can develop a light vegetarian diet, such as mung beans, melon and other foods that have the effect of relieving summer heat. At the same time, due to excessive sweating in summer, a lot of protein, vitamins, calcium and zinc will be excreted with sweat. The elderly can supplement protein in an appropriate amount, mainly with plant proteins such as beans, fungi and algae, but eat less "red meat" with high cholesterol. White meat such as chicken, duck and fish can be eaten properly, but don't overdo it. According to China.
