Allergies are an unpleasant reaction to your body’s sensitivity to various chemicals and substances. In some cases, you might find that your allergies cause a range of external and internal symptoms. Heredity can play a role in how allergies are spread to family members, but allergies in themselves are not contagious. Allergies are best treated by a doctor who can advise you of the proper types of medications to take as well as any preventive measures you can take.
Genetic Predisposition
Allergies are your immune system’s adverse response to certain substances. These substances can range from pollen, mold, dust mites, animal dander, foods and chemicals. According to National Jewish Health, you are more likely to develop allergies if these types of sensitivities run in your family. However, the types of allergies can vary among family members.
Weather Elements
Seasons and weather changes are partly to blame for an increased prevalence of allergens in the air. Mold spores as well as pollen grains from weeds, grasses and trees are common allergens that can cause a range of allergy symptoms. An allergy can be so severe that you might find it difficult to venture outdoors when certain allergens are present. According to the Asthma and Allergy Foundation of America, mold is especially difficult to avoid because it can grow year round, unlike certain types of pollen. Mold and pollen can be spread for miles through the wind.
In the Home
The Asthma and Allergy Foundation of America recommends that you refrain from going outside when allergen levels are high. You can carry allergens on your skin, hair and clothing, which are then transferred throughout your home. If you must venture outside, take a shower immediately after entering your house to wash off any mold spores or pollen grains. If you have pets, regularly vacuum all carpets and upholstery. Also consider a special filter for your air conditioning unit, and avoid opening the windows during allergy season. General diligence about cleaning can help reduce recurring allergy symptoms.
On the Skin
Certain types of allergy symptoms can spread throughout the body, particularly when they affect your skin. Although pollen and mold allergies are most commonly associated with nasal and sinus symptoms, they can also cause an allergic rash called eczema. Allergies to foods and chemical irritants can also cause this rash, which can spread throughout the body when left untreated. The best way to prevent the spread of allergic rashes to is avoid the allergens in the first place. The American Academy of Dermatology also recommends that you wear loose clothing and avoid any sudden drops or increases in temperature. Recurring rashes may be prevented with over-the-counter daily moisturizers for eczema. If eczema continues to spread despite preventive and treatment measures, see your doctor.
