Introduction
In cases of mild heatstroke, body temperature is slightly elevated but consciousness remains clear. Turning on the air conditioner can help lower the ambient temperature and promote body heat dissipation. At this time, set the air conditioner to around 26°C, avoid directing cold air straight onto the body, and ensure proper air circulation. This can relieve the heat discomfort without causing excessive temperature differences that might stimulate the body. In severe heatstroke accompanied by high fever and confusion, direct exposure to cold air from the air conditioner should be avoided.

Under normal circumstances, air conditioning can be used after heatstroke, but the method of use should be adjusted according to the severity of the heatstroke. If any abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:

Mild heatstroke is characterized by slightly elevated body temperature and clear consciousness. Using air conditioning can help lower the ambient temperature and promote body heat dissipation. At this time, set the air conditioner to around 26°C, avoid directing cold air toward the body directly, and allow air circulation. This can relieve stuffiness and heat without causing physical discomfort due to excessive temperature differences.

For severe heatstroke accompanied by high fever and confusion, direct exposure to cold air from the air conditioner should be avoided. The body is in a state of stress, and sudden exposure to cold air may cause blood vessels to constrict, impair heat dissipation, and potentially trigger other discomforts and worsen the condition.

When using air conditioning, pay attention to both temperature and airflow direction. In cases of severe heatstroke, do not attempt self-treatment; seek immediate professional medical assistance at a hospital.
