Health Watch -- Summer Allergies: Allergens and Ozone
We don't usually think of summer as allergy season. Spring is when most tree pollen is at full strength. But doctors at UT Southwestern Medical Center at Dallas say people with allergies can still suffer in the summer. This week on Health Watch, we'll talk about summer allergies and what you can do about them.
Dr. David Khan, a UT Southwestern allergist, says summer brings grass pollen and cedar elm, along with ozone. High summer heat doesn't affect the level of pollen in the air, but it does increase production of ground-level ozone that can make allergy symptoms even worse.
