It's of particular interest to write on this topic due to the fact that I live in Northern Virginia. In fact, you don't have to be allergic to trees, grasses, or flowers to be affected by the amount of pollen in the air. You may just be able to look at your car. It attaches to clothes and hair. Drive with your window open?
It doesn't help allergy suffers who are also a bit under stress. Constant stress is also related to allergy flare-ups. A recent study of 179 university employees found that 39% of the participants reported having symptoms of allergies during the duration of the study (more than one allergy flare). While cortisol levels were not associated with allergy flares, researchers did find a correlation between perceived stress levels and experiencing these allergy flare-ups. Among the high-stress study participants, 64% of them had more than 4 allergy flare-ups over the two 14-day periods in the study. The researchers also found an association between negative mood and allergy flare-ups-- "those with more flares have greater negative mood," they wrote in the study. (Huffington Post, April 2014)
Another study from the Journal of Investigative Allergology and Clinical Immunology (2013) states the chronic stress won't develop allergies, however, they can exacerbate symptoms and make treatment more difficult. Stress can weaken your immune system, thus making your allergy symptoms worse.
The moral of the story? Try to curb stress this allergy season. Get enough sleep, eat well, drink plenty of water, and exercise. Boss frustrating you? Take a quick walk and leave your desk for 10 minutes.
