Is the sultry climate in summer good for your health?
The effects of hot and muggy weather on human health are mainly heatstroke and death caused by cardiovascular and cerebrovascular diseases. Under the action of excessive ambient temperature, the thermoregulation mechanism temporarily fails, leading to heat accumulation in the body and heatstroke. According to the symptoms and degree of heatstroke, it can be divided into: heatstroke is the mildest manifestation of heatstroke and the most common; Thermal radiation refers to long-term work in a high temperature environment, which leads to vasodilation and congestion of the lower limbs, leading to fainting; Heatstroke is caused by long-term exposure, which leads to perspiration dysfunction. For patients with hypertension, cardiovascular and cerebrovascular diseases, in the environment of high temperature, humidity, no wind and low pressure, perspiration is inhibited, the stored heat in the body is increasing, and the myocardial oxygen consumption is increasing, which makes the cardiovascular system in a state of tension. The sweltering heat can also lead to vasodilation and increased blood viscosity, which is prone to symptoms such as cerebral hemorrhage, cerebral infarction and myocardial infarction, and may lead to death in severe cases.
Hot and sultry weather is a dangerous weather that leads to ischemic stroke. It's sultry in summer, and it's also prone to colds (Xia Han), diarrhea, skin allergies and other diseases.
The reason is that in the high temperature environment, human metabolism is vigorous, energy consumption is large, and sultry heat often makes people lack sleep and lose appetite, which leads to the decline of human immunity. At this time, if you don't control the use of air conditioners or electric fans to relieve summer heat, the human body will be in a low temperature environment for a long time, and its adaptability and resistance will decrease, and germs and viruses will take advantage of it and easily cause upper respiratory tract infections (colds). In addition, in the high temperature and high humidity environment, bacteria, viruses and other microorganisms multiply in large quantities, and food is easy to deteriorate, which will cause indigestion, acute gastroenteritis, dysentery, diarrhea and other diseases after eating; When people come home from the outdoor high temperature environment, they are used to turning on the air conditioner or directly blowing it with an electric fan and eating some iced food. This cold and heat will take effect immediately, and diarrhea will begin immediately. The sultry weather makes people sweat poorly, and it is also easy to cause skin allergies, mainly papular urticaria, eczema, contact dermatitis and so on.
