Allergy Facts

Mountainous regions may serve as allergy havens. Their high altitude does not permit many allergenic plants to grow, and their isolated location reduces outside pollen contamination to a minimum. A vacation to the mountains during peak allergy season may be a good idea for individuals suffering from hay fever.
