Seasonal allergies by the numbers

Seasonal allergies can flare up when plants produce pollen that become airborne, says ENT surgeon and board certified otolaryngologist Maureen Mulcahy of highly rated Lake Grove ENT in Lake Oswego, Ore. Weather conditions also can affect seasonal allergies. “When the weather is dry and there is wind or light breeze, the pollen will remain airborne longer and can travel farther,” she says. “Many people who suffer from seasonal allergies feel better when it’s raining — the pollen then sticks to the ground.” If your allergies are out of control, talk to an ear, nose and throat doctor or allergist, and check out these stats:
