As temperatures continue to drop, you may find yourself reaching for warmer clothes – among them wool sweaters. Many people claim they are "allergic to wool," but a true wool allergy is rare. Below are some quick facts that should help clarify wool allergies:

• A true allergic response to wool involves the same inflammatory immune system response that occurs with other allergies.
• More often, so-called wool allergies are actually sensitivities to the rough fibers of the wool.
• Those with atopic dermatitis, eczema, or sensitive skin in general should avoid wearing wool directly against the skin if they find the fiber irritating.
• Sometimes, an allergic reaction is not due to the wool fiber itself, but to the chemicals used to process and treat the wool. Try organic wool in this case.
• Lanolin is the source for many wool allergies. People who are allergic to lanolin will also react to lotions and other personal care products that contain lanolin.
• Reactions to wool can also be caused by other allergens that are contained in the wool, such as pet dander.
• Try wearing another layer between your skin and the wool clothing. If the sensitivity goes away, you have a sensitivity, not an allergy – and you found a way to continue using wool to stay warm!
