What is the reason for feeling bored?

The sultry weather is due to high temperature, low air pressure, low wind and poor air. 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.
