You may be allergic to cold if this happens to you
If you noticed your skin had rashes the last time you walked around when it was cold outside, you might actually be allergic to the cold, says Mayo Clinic. According to American Academy of Allergy, Asthma and ImmunologyCold urticaria – commonly known as cold allergy – is a rare and potentially dangerous skin allergy to cold temperatures.
Mayo Clinic further writes that eating or drinking something cold can cause your lips to swell. Sometimes your tongue or throat may swell (via Allergy and Asthma Network). In particular, the allergy can get worse when you try to warm up.
WebMD says other triggers include infections, insect bites, medications, as well as outdoor sports like swimming, skiing and mountaineering. Even a trip to the frozen aisle of your local grocer could cause a reaction.
In extreme cases, your body may have an anaphylactic reaction. By Medical News Today, you can take antihistamines before exposure to the cold or after your symptoms appear. Also, you may want to keep an EpiPen on you in case of anaphylaxis. However, your best option may be to avoid your cold triggers altogether.
