Why does the weather forecast have a threshold of 35 degrees?

35 degrees is close to human body temperature. If the outside temperature is equal to or even higher than the human body temperature, the human body temperature cannot be released. If the temperature inside the human body is too high, it will make people uncomfortable, easily burn the internal organs of the body, and even cause serious organ damage or even death. Therefore, the state clearly requires that when the temperature is higher than 35 degrees, the unit should give subsidies for heatstroke prevention and cooling.
