Skin conditions common in warmer weather

Summer means warmer weather, family vacations and a chance to enjoy the great outdoors. Hiking, camping, boating, biking, swimming and other outside activities are on many people's summer to-do list. But being outdoors also means exposure to intense sunlight, hot, humid temperatures, parasites, mites and poisonous plants.

Skin conditions common in the summer can be bothersome, uncomfortable and even painful. Some, such as heat rash and swimmers' itch, clear up on their own. Others, including Lyme disease, require medical treatment. Here's a look at these seasonal skin conditions, their causes and when you might need to see your doctor.
