Newswise — Itchy, watery eyes. Stuffy nose. Sneezing. Sound familiar? As much as we love it, warm weather can spell misery for the 20 to 30 million Americans who suffer from allergies.

According to Dr. Rachel Miller, Assistant Professor of Clinical Medicine and Public Health, NewYork-Presbyterian Hospital/Columbia University Medical Center, the majority of spring respiratory problems come from inhaling such allergens as tree or grass pollen and mold spores. Exposure to dust, pet dander, and other indoor pollutants can worsen the severity of spring and summer allergies, essentially adding fuel to the fire.

In addition, Dr. Elizabeth Leef-Jacobson, Assistant Attending Physician at the Iris Cantor Women's Health Center of NewYork-Presbyterian Hospital/Weill Cornell Medical Center, says allergies can trigger or worsen asthma and other respiratory illnesses.

Drs. Miller and Leef-Jacobson suggest the following tips to help allergy sufferers weather through the season:

- If you stay in air-conditioned areas with windows closed, you may reduce your symptoms. Be aware they will flare up the moment you go outside and may remain with you for the rest of the day.

- Window air-conditioning units do not filter out pollen and mold spores. If you use an air conditioner, keep it clean. Heating, ventilation, and air-conditioning systems harbor moisture, mold, and dust.

- If you suffer from mild symptoms, over-the-counter antihistamines will help for a few hours. Caution should be taken because they may cause drowsiness. Driving and operating heavy machinery should be avoided. Occasionally, older men develop urination problems when taking antihistamines.

- If you need more relief, over-the-counter antihistamines combined with a decongestant can relieve symptoms. But, read the package for health warnings. People taking multiple medications, and those with chronic medical issues like hypertension or prostate problems, should consult a physician.

- If you are concerned about your symptoms, please see your physician. In almost all instances, identifying allergic sensitivities and tailoring treatment with prescription drugs, nasal sprays, eye drops, non-sedating antihistamines or allergy shots, or specific allergen avoidance can help alleviate symptoms.
