In Singapore, the most common cause of allergic rhinitis is house dust mite allergies. You can reduce exposure to house dust mites by washing your child’s bedding (bed sheets, pillow cases and covers) in hot water that is at least 60 degrees Celsius weekly to fortnightly. Remove any stuffed toys out of the bedroom and minimise them around the house.
Minimise the use of fabric furniture, carpets or thick fabric curtains around the house. You can use acaricide sprays on heavy fabric material. Dust mite-proof pillow and mattress covers can be helpful but are expensive.
Use damp cloths for cleaning surfaces around the house to reduce dust accumulation. Use a vacuum for cleaning instead of sweeping up dust, preferably when your child is not at home. Allow the air to settle for about 2 hours before allowing them to enter the room.
If your child sleeps in air-conditioning, ensure that the air-conditioner and filters are cleaned and serviced regularly.
