Water. Red meat. Exercise. The sun. Money. Last month, we talked about some of the rare but real allergies some people have. But the list doesn’t stop there. Today, we’re going to talk about four more unusual allergens.Human skin allergiesSome people can develop a rash from simple contact with another person. In fact, these people can write their names on their skin with the touch of a fingernail. While there is no cure, antihistamines can minimize the irritation.Leather shoe allergiesSome people might find their feet breaking into uncomfortable rashes whenever they wear leather shoes because of the chemicals used to tan the leather. Antihistamines can help, but you might just want to wear socks or switch to another type of shoe altogether.Cold allergiesIn rare cases, extremely cold temperatures can cause anything from a rash to a sudden drop in blood pressure. While antihistamines can help, staying out of cold water and in warm areas is a good idea, too.Avocado allergiesLatex is a fairly common allergen, but did you know that a latex allergy can cause an avocado allergy, too? The proteins in avocados are similar to those found in natural latex, so if you know you have a latex allergy, exercise caution before ordering some avocado toast.Allergy care at CEENTAAllergies can come from many sources.
