There is no sun, but it is very hot. Will you get heatstroke?
But why are some people less affected by heat waves? The reason is mainly caused by the difference of people's heat resistance. The so-called heat resistance, in simple terms, refers to the body's tolerance to heat, mainly manifested in the body's tolerance to "sub-lethal high temperature" exposure. It is also in a state of high fever, and people who have survived have higher heat resistance; For people with low tolerance, this high fever can be fatal.
Many experiments have confirmed that the heat resistance of human body is related to heat stress protein, and the increase of heat stress protein synthesis is related to the degree and time of heating. Often in high temperature environment, the synthesis of heat stress protein increases, which enhances the heat resistance of human body. In the future, the damage degree of human cells will be significantly reduced when entering a high temperature environment.
Further research also reveals that the best way to obtain or improve heat resistance is to exercise at high temperature, that is, exercise at gradually increasing temperature to adapt to higher temperature environment. In early summer, the change of daily average temperature conforms to the characteristics of "gradual increase", which is the best time for heatstroke prevention exercise.
The specific methods of doing heatstroke prevention exercises in early summer are: setting aside an hour or so of outdoor activities every day, and choosing an environment with a temperature of about 25℃ and a humidity below 70% according to weather conditions to do exercises such as walking, running, gymnastics and boxing, so as to achieve the purpose of sweating every time, thus improving the heat dissipation function of the body. However, it should not be excessive, especially when the temperature is higher than 28℃ and the humidity is higher than 75%, the exercise should be reduced to prevent heatstroke.
