Introduction
In general, whether or not air conditioning can be used after applying the Sanfu贴 (herbal patches used in traditional Chinese medicine during the hottest days of summer) depends on individual circumstances. It is not recommended to be directly exposed to air conditioning immediately after application. If the ambient temperature is excessively high, air conditioning can be used cautiously while avoiding direct exposure on the area where the patch was applied. After applying the Sanfu贴, it is important to keep the application site dry and clean, and to avoid strenuous activities that may cause excessive sweating. Additionally, one should maintain a light diet and avoid cold or raw foods.

Generally speaking, whether one can use air conditioning after applying the Sanfu patch needs to be determined according to specific circumstances. It is not recommended to directly expose oneself to air conditioning immediately after application. If the ambient temperature is excessively high, it is acceptable to use air conditioning cautiously while avoiding direct exposure of the application site. Detailed explanations are as follows:

After applying the Sanfu patch, the application area may still have residual medication and the skin may remain sensitive. Direct exposure to cold air from an air conditioner may allow cold pathogens to enter the body, affecting the effectiveness of the warm nature of the medication and possibly irritating the skin, causing discomfort. At this time, one should stay away from air conditioner vents and wait until the medication is mostly absorbed and the skin condition stabilizes before entering an air-conditioned environment.

If the ambient temperature is extremely high and not using air conditioning may lead to excessive perspiration that could affect the patch's effectiveness, the air conditioner can be set to above 26°C. Avoid directing the cold air flow onto the application site directly. Additionally, maintain warmth while in the air-conditioned room, especially in areas such as the neck and shoulders, and the abdomen, to reduce the cold's impact on the body and balance the need for cooling with the effectiveness of the patch.

After applying the Sanfu patch, it is important to keep the application area dry and clean, avoiding strenuous exercise that may cause excessive sweating. If in an air-conditioned environment, wear loose and breathable clothing to protect the application area. Once leaving the air-conditioned room, engage in moderate physical activity to promote blood circulation. In daily life, also pay attention to maintaining a light diet, avoiding cold foods, and taking proper care to enable the Sanfu patch to exert its regulatory effects more effectively.
