Can you use air conditioning when you have chickenpox?

In general, patients with chickenpox can use air conditioning, but the temperature and airflow should be appropriately adjusted.

Air conditioning can reduce sweating by regulating indoor temperature, helping keep the skin dry and reducing the risk of blisters breaking and becoming infected due to sweat irritation. It also provides a comfortable resting environment. However, if the air conditioner is set too cold or blows directly on the patient, it may cause chilling, lower immunity, and potentially worsen the condition or prolong the illness. Therefore, the use of air conditioning should be flexibly adjusted according to the patient's physical condition and the actual environment.

Exposure to low temperatures from air conditioning may cause chilling, leading to symptoms such as colds and headaches. Direct airflow from the AC may cause skin blood vessels to constrict, affecting circulation and delaying rash resolution. Dry air may intensify skin itching, increasing the risk of scratching, infection, and scarring. It is recommended to keep the air conditioner set between 26°C and 28°C, avoid direct blowing, and regularly open windows for ventilation to maintain fresh indoor air and reduce bacterial growth.

While using air conditioning, chickenpox patients should maintain clean skin, avoid scratching, keep fingernails trimmed, and wear gloves if necessary. The diet should be light, with plenty of foods rich in vitamins, while avoiding spicy or greasy foods. For patients with weak constitutions or sensitivity to temperature changes, natural ventilation or fans may be preferable for regulating indoor temperature, thus reducing reliance on air conditioning. Additionally, closely monitor the progression of the illness, and seek medical attention promptly if symptoms such as high fever or pus-filled rashes occur.
