You've been letting in the sunshine—along with less delightful things.
It's spring—time to air out the house to help you breathe easier...except this can make the pollen levels inside the house as bad as they are outside, Bajowala says. Raise the shades but keep the windows closed when the pollen count is high (check local levels at the National Allergy Bureau web site ). Instead, get rid of dust and other allergens with central air-conditioning or an air filter (clean or change filters once per season to keep them working properly).
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
