Expert advice on navigating longer and stronger allergy seasons.

Experts warn that Southern California will experience one of the worst spring allergy seasons due to the unusually high amount of rain that has broken up pollen. To avoid symptoms, allergist-immunologist Dr. Salima Thobani advises people to start using nasal steroid spray a couple of weeks before the season starts, take over-the-counter antihistamines, wear a wide-brimmed hat and sunglasses while hiking, and stay on top of the pollen forecast. Thobani also recommends using masks to keep allergens from getting to your nose and taking a shower after being exposed to pollen.
