Children’s Allergy Symptoms
Allergy testing by an allergist can help assess whether your symptoms are caused by dust mites, pet dander or mold.
Pet Allergies
Pet Allergies
If furry friends give your kid a runny nose and itchy, watery eyes, it’s not their fur that causes the allergic reaction. It’s the proteins found in the animal’s dander (dead skin cells), saliva or urine. These allergens are transported to the skin or fur, where kids touch dogs and cats most often. These particles are so light that they can be transported in the air and carried on your child’s clothes and hair.
Tips for Kids with Pet Allergies
Tame Four-Legged Friends
Keep furry family members out of your child’s bedroom and be sure to teach your kid to wash his or her hands after playing with pets.2
Scrub-a-dub-dub
If you have a pet, giving him or her regular baths can reduce your kid’s exposure to their allergens.
Be Picky About Pets
Consider babysitting or fostering a pet before adopting to see if he or she affects your kid’s allergies. Cats may cause more allergy symptoms than dogs. But remember, even furry animals that don't shed can cause pet allergy symptoms.
Play Smart
If you are bringing your child to a playdate at a friend’s house, ask if they have pets so you can be prepared with allergy medicine if your child’s symptoms strike.
Dust Allergies
Dust Allergies
Overview
Dust mites are found in the dust particles that collect naturally around your home. These microscopic creatures live off dead skin cells, hiding in household fabrics, such as pillows, mattresses, upholstered furniture, blankets, carpets and stuffed animals.
Dust mites are more prevalent in humid areas of your home and during the summer months. However, if you live in a warmer, more humid climate, they’re prevalent year-round.
Tips for Kids with Dust Allergies
Reduce Dust Bunnies
Toys, knick-knacks and other clutter can be magnets for dust mites and other allergens. Be sure to dust with a damp sponge or mop regularly and use a vacuum with a HEPA filter or double bag. Store all your child's clothes in drawers and closets to help reduce dust build-up.3
Sleep Tight
To help reduce allergen build-up, wash all bedding and blankets regularly in hot water (at least 130°F).3 Always follow washing directions. Vacuum your child’s mattress every two weeks or use a special dust-mite cover for his or her mattress and pillow. You can also invest in hypoallergenic pillows, mattresses and furniture.2
Take Stuffed Animals for a Spin
Dust mite droppings can build up on stuffed animal fluff over time. To kill these microscopic allergy triggers, wash stuffed animals in hot water regularly. It’s also a good idea to limit the number of stuffed animals on your child’s bed to one or two favorites, so they’re exposed to fewer dust mites at night.2
Ditch The Carpet
Wall-to-wall carpeting is soft and cozy on little feet, but it’s also a magnet for many indoor allergens, including dust, pet dander and mold. Consider replacing carpet with hardwood floors.2
Mold Allergies
Mold Allergies
Overview
Microscopic mold spores that float in the air like pollen can trigger kid’s mold allergies. Indoor molds shed spores all year and are found lurking in damp spots, such as basements, bathrooms, laundry rooms, attics, refrigerators and windowsills. Since mold thrives in damp spaces, your child may experience allergy symptoms more during the summer months when it’s hot and humid. But they can be prevalent year-round in the South and on the West Coast.
Tips for Kids with Mold Allergies
Clean House
Help prevent mold with regular bathroom, laundry room and basement cleanings. Don’t leave damp laundry lying in the washing machine for long periods of time. Wash shower curtains and bathroom tiles, grouting and fixtures with mold-killing and mold-preventing products. Use machine washable bath mats in the bathroom.
Dehumidify
Keep the relative humidity in your home below 50 percent. You can get a hygrometer (humidity monitor) at many hardware stores to measure your home’s humidity.3 When it’s humid, place a dehumidifier in damp areas and your kid’s bedroom to keep humidity in check.
Lighten Up
Mold doesn't like sunlight, so try to keep the curtains or shades open during the day, especially in your child’s bedroom.
Go Hypoallergenic
Sweat can make pillows, mattresses and furniture filled with foam rubber moldy. So be sure to check the label for “hypoallergenic."
