Stop that itch!
Few things are more maddening than an itch. And summer is prime time for all kinds of creepy-crawly sensations, often accompanied by mysterious lumps, bumps, cracking, crusting, swelling, and oozing (delightful!). “Most itching has an obvious cause, such as bug bites or dry skin.
Hot, humid weather brings on this rash, in which clogged sweat ducts trap perspiration under the skin. It shows up as tiny, itchy bumps or blisters, most often in skin folds or places where clothes cause friction.
Technically, it’s not poisonous. But an estimated 85% of people are allergic to the urushiol oil in poison ivy, poison oak, and poison sumac. Brushing up against one of these creepers can result in red raised patches, often with blisters, swelling, warmth, and, of course, itching; the reaction usually appears 12 to 72 hours after exposure.
You already know that warm, moist conditions can contribute to a vaginal yeast infection, caused by an overgrowth of a fungus called Candida albicans. It can also develop when the acidic balance in the vagina shifts, such as after you’ve taken antibiotics or steroids, during pregnancy and menstruation, and when taking birth control pills.
The name conjures up grimy locker rooms, but you can get athlete’s foot even if you’d never dream of strolling around barefoot at the gym. This fungal infection can take hold if your feet get sweaty in closed-toe shoes, if you have a minor skin or nail injury, or even if you get a pedicure with poorly sterilized tools. Its calling card: cracked, flaking, peeling skin between the toes, along with oozing and crusting blisters.
Hives are a common reaction to many different allergens, including animal dander, insect bites, medications, pollen, or foods, as well as infections (such as mononucleosis). Occasionally, they pop up when you’re stressed, exposed to extreme cold or sun, or sweating profusely.
