Protect Yourself From Pollen

Created April 30, 2019

Many types of pollen cause mild to severe seasonal allergy, including allergic rhinitis and asthma. But helpful defenses are available, according to researchers at the National Institute of Environmental Health Sciences.

Plant Pollen
Pollen amounts are highest in the morning, and on dry, hot, windy days.

Protecting yourself
  • Between 5 and 10 a.m., stay indoors. Save outside activities for late afternoon or after a heavy rain, when pollen levels are lower.
  • Keep windows in your home and car closed to lower exposure to pollen. Keep cool with air conditioners. Don’t use window or attic fans.
  • Use a dryer, not a line outside; dry your clothes and avoid collecting pollen on them.
Grass Pollen

Grass pollens are regional as well as seasonal. Their levels also are affected by temperature, time of day, and rain.

Protecting yourself
  • Have someone else mow your lawn. If you mow, wear a mask.
  • Keep grass short.
  • Grow ground covers that don’t produce much pollen, such as moss.
  • Treat respiratory allergy with antihistamines, topical nasal steroids, cromolyn sodium, decongestants, or immunotherapy.
  • Use an air purifier with high efficiency air filters (HEPA) or an electrostatic air filter.
