Preventing Allergies
Monday, April 28th, 2008
For most people, after a long winter, the budding of trees and spring flowers can be a greatly anticipated time of year. However, for allergy sufferers, it can be an unwelcome time as sneezing, runny nose and itchy eyes prevail. Being proactive with your health during allergy season can vastly prevent most symptoms and make springtime a time to be outdoors.
Histamine is a neurotransmitter that is released from mast cells when the body is exhibiting an allergic reaction or immune response. Histamine dilates blood vessels and increases blood vessel permeability. This leads to visual signs in the body such as localized swelling, warmth, and redness. Histamine also irritates nerve endings that can lead to itching and pain. The bump and redness immediately following a mosquito bite is a good example of this reaction, which occurs seconds after challenge of the mast cell by an allergen. If you are a person whose body “over-reacts” to bug bites, then your body likely has a tendency towards inflammation and allergy.
Try taking a daily dose of Vitamin C. Research shows that 1-gram a day can help to reduce overall histamine levels in the body. Foods that tend to increase histamine levels in the body are strawberries, tomato, chocolate, wine, bananas and shellfish. These foods should be limited or avoided all together during allergy season. In general, dairy foods such as cheese, milk and yogurt should be avoided as well, as they have a tendency to cause generalized inflammation and can create more mucous if it already exists.
Berries such as blueberries, cherries, and raspberries as well as mango contain a good amount of bioflavonoids. These phytochemicals stabili
ze mast cells in the body and decrease overall histamine response, thus reducing inflammation.
Lastly, try using a HEPA air filter. It can reduce dust in the bedrooms and main living areas as well as eliminate circulating pollen that enters through open windows. Be sure to keep windowsills wiped down in the bedroom and sweep under the bed. Keep in mind; the bedroom should be the most dust-free room in the house as this is where you will have the most concentrated period of breathing throughout the day!
