How to Cool Hayfever Summertime is sneezing' season for people who have hay fever. For them, Mother Nature is sending out tiny 'guided missiles' in the form of pollen grains and mould spores. If you're a hay fever sufferer, it might help to know you're not alone. The National Institute of Allergy and Infectious Diseases based in Bethesda, Maryland, estimates that 35 million Americans experience upper-respiratory allergic reactions to airborne pollen. Why Do I Sneeze? Hay fever is another term for allergic rhinitis, a condition that seasonally affects people who are allergic to pollen or mould, and year-round affects people who are allergic to house dust or furry animals. It's thought that people inherit the tendency to have allergies. Problems occur when a person's immune system reacts to the pollen, mould, dust, or other irritant as if it were an alien invader. The result is watery nasal discharge; sneezing; coughing; itchy eyes, nose, and throat; nasal congestion; and dark circles under the eyes. Pesky Pollen Pollen allergies are common during spring, summer, and fall, are caused by trees, grasses, and weeds. Weeds deserve their bad reputation as heavy pollen offenders; ragweed is the major culprit. Though more than 1,000 species of grasses grow in the U.K, only a few produce highly allergenic pollen. Trees that produce allergy-causing pollen include oak, ash, elm, hickory, pecan, box elder, and mountain cedar. But it won't do much good to rid your yard of these offenders; air currents carry pollen many miles from its source. Surprisingly, most flowers aren't big allergy producers because their pollen grains are large and heavy and are more likely to be carried on the backs of bugs than by the wind. Mould Takes Hold In cold climates, the season for mould allergies are similar to that for pollen allergies but extends to late fall. Freezing temperatures and snow cover keep the mould population in check; however, in warm climates, moulds are plentiful all year and can cause year-round allergies. Like plants, only a small number of moulds are allergy offenders. Outdoors, popular mould hangouts include moist, shady areas, and indoors moulds tend to congregate in damp basements, closets, and bathrooms. Culprits on the Home Front People who have hay fever symptoms all year are probably allergic to house dust, down, and fur bearing house pets. When seen under a microscope, house dust is a potpourri of fibres, feathers, bacteria, mould, food particles, and dust mites. In urban areas, the waste products of cockroaches can cause allergy symptoms. It's not animal fur that causes allergies; it's the protein in animal saliva that the critters deposit on their fur during grooming. Since cats are constant purrers, it's easy to see why they are more of a problem. See "Breathe Easier Around Cats," below. Regaining Control It's important to control hay fever because if it is left untreated, complications such as sinus infection, sinus headaches, chronic fatigue, ear infections, and even asthma may develop. And always feeling sick can disrupt your sleep and make you irritable. See "Stay Fit During Hay Fever Season," at bottom. Getting the upper hand over allergies requires a two-part approach, limit your exposure and treat your symptoms. Limit your exposure: If you're sensitive to pollen, it helps to:
If household allergies are a problem, it helps to:
Dehumidify the basement to discourage mould growth, and empty the dehumidifier water tank often. Address your symptoms
Several products combine antihistamines and decongestants. People react differently to these medications; so if you aren't finding relief after about 5 days of use, consider trying a different one. See your doctor if symptoms worsen or you find that you're increasing the amount of medication to control them. A doctor
may perform medical tests to target the likely cause of your allergy.
And your physician may recommend one of the many prescription
medications that are effective for treating allergies, including
antihistamines, topical nasal steroids, and cromolyn sodium. Animal fur isn't really the cause of allergies; it's a protein in animal saliva that's the culprit or allergen. Pets, particularly cats, spread the allergen around when they groom themselves. The National Institute of Allergy and Infectious Diseases, based in Bethesda, Maryland, advises cat lovers to reduce their exposure to the allergen by bathing cats weekly, brushing them often (with a face mask on if needed), and keeping them out of the bedroom. Stay Fit During Hay Fever Season Hay fever and sports don't mix well. Exercise doesn't sound very enticing when you're sneezing and your nose is running. And to make matters worse, some sports situations expose people to the pollens or moulds they're trying to avoid. But these simple preventive measures may help you stay on your fitness course, even when the pollen is heavy.
