Introduction
Individuals with mild heatstroke may experience slightly elevated body temperature along with symptoms such as dizziness and fatigue. Moving them to an air-conditioned room and adjusting the temperature to 26-28°C, while avoiding direct airflow onto the body, can help dissipate heat and alleviate discomfort. At this time, the body can still tolerate mild cool air without being stimulated by excessive temperature differences. However, direct exposure to air conditioning is not recommended for individuals with severe heatstroke and a rapid rise in body temperature.

In general, individuals with mild heatstroke can appropriately use air conditioning to lower their body temperature, while those with severe heatstroke and a sudden rise in body temperature should not be directly exposed to air conditioning. If any abnormalities occur, it is recommended to seek medical attention promptly. Detailed explanations are as follows:

Individuals with mild heatstroke may experience slightly elevated body temperature and symptoms such as dizziness and fatigue. Moving them to an air-conditioned room with the temperature set at 26-28°C and avoiding direct exposure to the cool air can help dissipate heat and alleviate discomfort. At this stage, the body can still tolerate mild cold air without being stimulated by significant temperature differences.

For severe heatstroke, when body temperature exceeds 40°C and is accompanied by confusion, direct exposure to air conditioning can cause blood vessels to constrict suddenly, hindering heat dissipation and possibly triggering chills, thus increasing physical stress. In such cases, physical cooling methods such as wiping the body with lukewarm water should be used first. Air conditioning should be cautiously introduced only after the body temperature has slightly decreased.

Caution should also be exercised when using air conditioning for elderly individuals, children, pregnant women, and other individuals with weaker constitutions after experiencing heatstroke. These populations have a poorer ability to adapt to temperature changes, and both excessively cold or hot environments may negatively affect their health.
