What you can do
Dust mites
Your child has severe eczema that treatment and skin care do not help.

Trying to control dust mites can be difficult. These microscopic bugs live in everyone's home. The following can reduce dust mites:

  • Place dust mite covers on your child's pillows and mattress.
  • Wash your child's bedding weekly in hot water. Use a fragrance-free, dye-free laundry detergent.
  • Remove rugs and carpets from your child's room.
  • Dust your child's room weekly.
Dry air Child's eczema flares during the winter or you live in a dry climate. Follow the tips found in Winter skin care for eczema.
Heat Your child seems hot (or sweats) and starts to scratch.

Prevent overheating.

  • Remove clothing as needed.
  • Avoid too many covers at night.
  • Air-condition your home when the temperature rises above 75º F.
Humidity Your child seems itchy when it's humid. Keep your home's humidity at a comfortable level.
Pet dander Your child's eczema seems to flare around animals. If you have a pet with fur or feathers, remove the pet from the home for a few weeks. If the eczema lessens, pet dander could be a trigger. Talk with your child's dermatologist about possible solutions.
Sudden change in temperature Your child seems uncomfortable and starts to scratch after a sudden temperature change.
Tobacco smoke
Eczema appears on your child's eyelids or your child's eczema flares when someone smokes.
To protect everyone's health, ban smoking inside your home. If someone must smoke, make sure the person smokes outdoors.
