Allergy Season Tips
It's impossible to completely escape pollen and molds; here are some other ways to lessen exposure:
- Keep windows closed and use air-conditioning, if possible. Automobile air conditioners help, too.
- Remember to change your home and auto air filters and replace them with high efficiency filters.
- Outdoor air usually is most heavily saturated with pollen between 5 a.m. and 10 a.m., so early morning is a good time to limit outdoor activities. Mold spores, however, are released due to wind, or other activities that stir them up.
- Wear a NIOSH-rated 95 filter mask when mowing the lawn, raking leaves or gardening and take appropriate medication beforehand.
- Use your allergy medications as prescribed daily to prevent allergy exacerbation.
- Do not forget you allergy shot even is you are feeling OK. Remember you need to complete course of treatment in order to benefit from it.
