1. Take the shower before going to bed. You will not rub pollen in to your pillowcase and breathe it in all nigh.
2. Cover your bed with bed-cover, to prevent dust and allergens getting in your bed.
3. Wash your hands and face often. Don't pick your nose and eyes!
4. Was your windows and draperies. Remove carpets, window-blinds and clean, clean, clean and then clean some more!
5. Use Saline Nasal Mist to flush pollen out of your nose, BEFORE you spray medicated Flonase!
6. Air purifiers are great!
7. Don't use cough suppressant, use expectorant!
...and pray for allergy immunity.
