I am allergic to pollen, cats, dust, etc. I posted these suggestions on a previous thread about allergies. I've added some too:
~ don't open the windows in your house when pollen count is at its highest (between 5 and 10am)
~ use your air conditioning (if you have it) and don't open your windows at all on high pollen count days
~ I get an email every day from pollen.com telling me what the pollen count is in my area and I plan my day accordingly
~ don't drive with the car windows open during pollen season (you are exposing yourself to so much pollen at once, and so many different kinds...)
~ use a neti pot to alleviate congestion
~ give up dairy (it is *so* congesting!! this has helped me incredibly with my sinus problems)
~ don't do the dusting or vacuuming (if you have to do this kind of stuff, at least wear a mask)
~ don't have lots of carpets (hardwood floors are great!)
~ get rid of stuff that collects lots of dust (stuffed animals are the worst!)
~ shower or change clothes after coming in contact with irritants (like after being in your yard/garden, or for me, after visiting someone who has cats! Just wash all that stuff off!)
~ don't hang your clothes or bed linens outside to dry -- they will get covered with pollen.
~ I don't take antihistimines (they make me drowsy) or decongestants (over time, if taken frequently, they actually thicken mucus, making congestion & sinus problems worse).
~ I take homeopathic tablets I get from Whole Foods (Hyland? I think that's the brand name)
