Five Surprising Allergy and Asthma Triggers That Can Spoil Summer Fun

Rather than lazy, hazy and crazy, summer can be sneezy, itchy and wheezy for those with allergies and asthma. Millions of Americans are allergic to grass pollen, a trigger from late spring to early summer. But suffering also may be caused by unexpected triggers, such as mold spores, campfires or changes in the weather.

"Summer is full of allergy and asthma triggers that many people are unaware of," said allergist Rodney Johnson, M.D., of Middle Georgia Allergy and Asthma. "If you are vigilant to avoid them and treat your condition, it can mean the difference between a great summer and a miserable one."

The following are a few surprising summer allergy and asthma triggers, as well as some suggestions for coping with them, courtesy of Dr. Rodney Johnson, M.D.

• Mold. Allergenic mold spores are problematic throughout the summer and fall, and may outnumber pollen grains in the air. Mold thrives in very warm and humid environments and can grow well indoors or outdoors. Keeping the humidity low (< 50%) and making sure there are no water leaks in the home will prevent the growth of mold.
• Summer fruits and veggies. If your lips start tingling soon after you sink your teeth into a juicy peach or melon, tomato, celery or orange you may have oral allergy syndrome. People with grass allergies can suffer from this condition, which is a cross-reaction between similar proteins in certain fruits and vegetables and the allergy-causing pollen. The simple solution is to avoid the offending food, or just put up with the annoying but short-lived (and seldom dangerous) reaction. In rare cases, the problem can cause a life-threatening reaction called anaphylaxis.
• Changes in the weather. Be it stifling humidity or a refreshing cool breeze, sudden changes in the weather can trigger an asthma attack. See an allergist to discuss an asthma action plan and to be sure you are keeping your asthma in check no matter the season or the temperature.
• Campfire smoke. Toasting marshmallows or sitting out at a bonfire is a lot less fun if it results in an asthma attack or allergic reaction. Smoke is a common asthma trigger, and some folks are allergic to the pollen of the wood being burned, such as mesquite. If you don't want to miss out, sit upwind of the smoke and avoid getting too close.
• Stinging insects. As if the pain isn't bad enough, you can develop a life-threatening allergic reaction to the sting of bees, wasps, hornets and fire ants, even if a previous sting only caused a mild reaction such as a rash. Cover up when gardening or working outdoors, avoid brightly colored clothing, forget the perfume and take caution when eating or drinking anything sweet, all of which attract stinging insects. Ask an allergist if you should carry portable epinephrine just in case you are stung.
