How long will the hot weather last in Guangxi?

The high temperature generally starts in mid-July and ends in mid-August, lasting about one month, but the specific number of days may vary from year to year according to weather phenomena.

The effects of high temperature weather on human health are mainly heatstroke, cardiovascular and cerebrovascular diseases and death.

Under the action of high ambient temperature, the thermoregulation mechanism is temporarily blocked, and heat accumulation occurs in the body, leading to heatstroke. According to the symptoms and degree of heatstroke, it can be divided into: heatstroke is the slightest manifestation of heatstroke and the most common; Thermal radiation, working in high temperature environment for a long time, leads to vasodilation, congestion and fainting of lower limbs; Heatstroke is due to long-term exposure to the sun, leading to perspiration dysfunction.

For people with hypertension, cardiovascular and cerebrovascular diseases, in the windless, low-pressure, high-temperature and humid environment, 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 prone to symptoms such as cerebral hemorrhage, cerebral infarction and myocardial infarction, and may even lead to death.
