What effects will high temperature weather have on human body?

Every degree of temperature rise in midsummer may have adverse effects on the weak or the elderly. Because the temperature itself has a warning effect. For example, at 33 degrees, people will feel hot, which is the starting temperature for heatstroke prevention and cooling. At 35 degrees, the forms of radiation, convection and conduction that the human body relies on for heat dissipation gradually weaken or stop, and evaporation, that is, sweating, is also the most important or even the only way to dissipate heat. Therefore, it is necessary to replenish water and electrolytes such as potassium, sodium and magnesium in time. There will be a first-class alarm when the temperature is 37 degrees. At this temperature, people may be dehydrated or have electrolyte disorder due to excessive sweating. There will be a second and third alarm when the temperature is 38 degrees to 39 degrees. Some people, especially those with weak constitution, may be at a loss and have accidents. Physical cooling and drug prevention should be carried out at this time. Medical experts believe that when the temperature rises to 38 degrees Celsius, although the temperature is 35 degrees Celsius, heatstroke and cardiovascular and cerebrovascular accidents may occur if the humidity is too high.
