This allergen blooms when the temperatures drop

When a drop in humidity levels occurs - like during the change from summer to fall - you may be sniffling thanks to ragweed

In our Facebook Story of the Day, you wanted to know what can irritate your allergies now that the weather is cooler.

Dr. Tracy Bridges of the Allergy and Asthma Clinics of Georgia says during a drop in humidity levels -- like the change from summer to fall -- allergy sufferers will be affected by ragweed.

The obvious allergic reactions to ragweed include a runny nose, sore throat from a post-nasal drip, dry or itchy eyes and other signs that can be mistaken for a common cold. However, some people will experience headaches and fatigue.

Experts say your best defense is to schedule an appointment to be tested for specific allergens but if you don't have time, over the counter remedies like nasal sprays and antihistamines are a short-term answer.

Dr. Bridges says if you're looking for a long-term fix, allergy shots -- a personalized serum for your specific needs -- are available. The shots work to build your immunity to what makes you sniffle so that you eventually don't react to them anymore.

Lastly, to lessen your chances of sitting in on a Friday night with a box of tissues and Benedryl, avoid inhaling the cool air outdoors. Allergists say fight the urge to open your windows because that's the easiest way to let the allergens into your home.
