Hay fever, a common condition in the US, affects people of all ages. "Hay Fever is a generic term for a pollen allergy," explains Timothy Craig, D.O., an allergy researcher and associate professor of medicine at Pennsylvania State University Hershey Medical Center. People who have hay fever also may experience sleepiness, poor sleep, wheezing, and a dry throat. New allergy sufferers may think they have a cold until noticing that the same "cold" reoccurs each spring, summer, or fall. Allergies develop when the immune system perceives airborne tree, grass, and weed pollens - items which are normally harmless - as invaders. The immune system reacts by developing antibodies or sensitized cells that produce a host of protective chemicals, including histamine, to fight off perceived threats. This defense triggers congestion, stuffiness, and sneezing. The more you come in contact with allergens the more "sentisitized" you become, increasing your odds of suffering an allergic reaction. Studies show that if your parents have allergies, you may suffer too. Allergies can reappear after years of remission, and they can develop at any time. The severity of the symptoms seems to diminish with age. The American Academy of Allergy, Asthma and Immunology suggests these tips to lessen exposure to pollen or molds that trigger allergies:
- Keep windows closed to prevent pollens and molds from drifting into your house.
- Keep car windows closed when traveling.
- Use an air conditioner in your home or car to keep the air dry and cool.
- Try to stay indoors when the pollen count or humidity is high.
- At the height of pollen season, take a vacation to a pollen-free area, such as a beach.
- Don't hang sheets or clothing outside to dry.
- Don't mow the grass or rake.
- Don't grow too many indoor plants or overwater your plants; wet soil encourages mold growth.
