Q: Should we move to help my daughter's spring allergies?
A: Moving from a humid area to an arid one may help with allergies to house dust mites, but not with outdoor allergies. Even in bone-dry regions, grasses, olive and mesquite trees, and weeds (including ragweed) grow well and release their pollen into the wind. Molds (mostly in soil) also grow well. Dry, hot desert air can irritate already inflamed nasal and throat tissues. Consult a board-certified allergist before making any decision to move. -- Brian Vickery, MD, WebMD's Children's Allergies Expert
