When entering an air-conditioned room or allergic place, carry a mask with you and put it on immediately. Wear a mask or scarf to cover your mouth and nose when riding a motorcycle or breathing uncomfortable cold air.
3 control the use of air conditioners at home, especially for allergic children. It is best to blow the air conditioner as little as possible. When using the air conditioner, you should always clean and replace the filter screen, often wipe the air outlet of the air conditioner, reduce the indoor furnishings, and often clean it to avoid the indoor allergens rising when the air conditioner blows.
4 Drink more hot water because the heat of the mouth will increase the temperature of the nasal cavity and reduce the chance of nasal mucosal swelling, so drinking more hot water will also help to relieve nasal allergies.
