why skin allergy occurs

Skin allergies occur when the immune system overreacts to a harmless substance, treating it like a threat. These triggers, called allergens, can include anything from pet dander to soaps, or even changes in temperature or humidity. Interestingly, skin allergies can suddenly appear—even if you’ve never experienced them before. You mentioned petting your dog; pet dander can sometimes trigger reactions, even if you hadn’t had issues before. Allergens might accumulate over time, or your body’s sensitivity might change. Stress has also been known to exacerbate allergies by releasing certain hormones that can alter your immune response. Since you’re experiencing stress with work, this could have potentially heightened your vulnerability. Switching soaps was a good step, as contact dermatitis from soaps or shampoos is a common reason for skin allergies. It’s also worth considering if you’ve come into contact with new materials or products, like laundry detergents or lotions. As for whether it’s something serious, most skin allergies are annoying but harmless. However, if rashes become severe, or if you see signs like blisters, swelling of the face, or difficulty breathing, seek immediate medical attention—those particularly could be signs of a serious reaction called anaphylaxis. Otherwise, over-the-counter antihistamines or topical corticosteroid creams often help with mild rashes. Remember to patch-test any new products to check your skin’s response. If recurrent or severe, you migjt want to see a healthcare professional, who might suggest allergy testing to pinpoint triggers more precisely. This way, you will have a targeted plan preventing future flare-ups.
