What should I do if my face swells up from sitting in air conditioning?

Facial swelling after using air conditioning requires identifying the underlying cause before appropriate treatment can be provided. Common causes include allergies, facial neuritis, and kidney disease.

1. Allergy

If the air conditioner's filter has not been cleaned for a long time, large amounts of bacteria may grow inside the unit. When using the air conditioner, these bacteria can come into contact with the facial skin and trigger allergic reactions. In addition to facial swelling, symptoms such as itching may also occur. In such cases, antihistamine medications—such as loratadine tablets or cetirizine hydrochloride tablets—can be taken under medical guidance.

2. Facial Neuritis

Setting the air conditioner too cold or exposing the face directly to strong airflow may lead to facial neuritis, which can cause facial swelling. This condition is often accompanied by symptoms including facial stiffness, pain, and numbness. In severe cases, it may result in facial drooping, drooling, and misalignment of the mouth and eyes. Prompt treatment is essential, including early administration of corticosteroids such as prednisone tablets or dexamethasone tablets. Additionally, neurotrophic agents like vitamin B1 and mecobalamin dispersible tablets should be used. Local heat application, massage, and acupuncture may also support recovery.

3. Kidney Disease

In patients who already have kidney disease, swelling is a common symptom and is generally unrelated to air conditioning use. These individuals should seek medical evaluation and follow their doctor’s instructions for taking diuretics such as furosemide tablets or hydrochlorothiazide tablets.

In addition to the above treatments, patients should pay attention to their diet by consuming light, easily digestible foods. They should also stay warm to avoid worsening their condition.
