Reduced heat resistance

Introduction The human body has strong heat resistance. When the outside temperature exceeds 35 °C, the skin will accelerate the heat through sweating to ensure that the body temperature does not rise excessively. However, air-conditioning is taking away people's heat-resisting skills, especially white-collar workers who have been sitting in the office for a long time, students who are on vacation at home, and their heat-resistant stress proteins are significantly reduced. Once they enter a high-temperature environment, they are easily stroked. When the air reaches a certain limit, the body's heat cannot be dissipated, and exceeding the human endurance limit poses a danger.

Cause

Long-term in air conditioning, skin sweating is reduced, heat resistance is degraded, and heat-resistant stress proteins are significantly reduced.

Thermal release test

In fairly dry air, healthy people can stay in the high temperature of 50 ° C for 2 hours; stay in the high temperature of 70 ° C for 15 minutes; stay in the high temperature of 100 ° C for 3 minutes without any damage. The thermal sensation of the human body is also related to the humidity of the air. When the temperature is higher than 28 ° C and the absolute humidity (water pressure) is greater than 30 hPa, people will feel stuffy and hot. According to the experiment, if you stay in saturated humid air at 45 ° C for 1 hour, heat stroke coma will occur.

Differential diagnosis

"Heat failure": that is, due to long-term dependence on air conditioning, her heat resistance is reduced. Once she encounters high temperature, her body can't dissipate heat due to her self-adjustment and coordination ability.

"Air conditioning heatstroke": Stayed in a non-ventilated room for a long time, and did not replenish water in time to cause dehydration.
