If you’re one of the tens of millions of Americans who suffer from pollen allergies, you know that even a quick run or walking the dog can mean itchy eyes and a runny nose. Here's what to do.

Spring arrived early this year — in some places up to three weeks. What does that mean for your health?

Winter squash is indigenous to North America and was a staple in Native American diets. According to the World’s Healthiest Foods website, winter squash is grown between August and March, with peak season running during October and November. Winter squash is not commonly an allergenic food.

For someone who needs relief from head and chest congestion and clogged sinuses, the Personal Steam Inhaler by Vicks may be able to help. This system uses the warm, moist heat caused generated by steam in order to soothe clogged and irritated airways in the respiratory system.

If you have a chronic cough, you’re not alone. Coughing is a symptom of seasonal allergies, and more than 50 million Americans deal with allergies every year, according to the Centers for Disease Control and Prevention.

An allergy is an exaggerated abnormal immune response to something in the environment that normally would not be harmful. One of the most common types of allergies is the seasonal allergic rhinitis, or hay fever. Hay fever affects one in five people, according to MayoClinic.

Seasonal allergies affect your entire upper respiratory system. When you feel your allergies take over, clogging your nose and causing post-nasal drip, you may begin coughing to relieve the tickle in your throat. If your coughing becomes bad enough, it can sound like croup.

For those who are sensitive to pollen, dust mites and weeds, certain times of the year may make them feel under the weather. While a seasonal allergy attack is not a true illness, the body’s response to allergens may make the sufferer feel sick.

The symptoms of seasonal allergies -- excessive mucus production, runny nose and congestion -- are caused by allergens, such as pollens or molds. Seasonal allergies do not directly cause swollen lymph nodes.

Seasonal inhalant allergies can make you feel like you’re sick but will not cause sickness. It’s difficult to distinguish between allergy symptoms and the common cold because the two conditions cause similar reactions in the body.

Indoor or outdoor, seasonal or year-round, all types of allergies can potentially cause constant coughing. Along with a runny nose, sneezing and watery and itchy eyes, allergic cough can be disruptive and annoying.
