What causes chafing?
Chafing is a skin irritation. It generally resembles a red rash and is caused by intense rubbing between body parts or another surface, such as clothing. Inner thigh chafing is a common side effect of walking or running. The risk is often higher among those who suffer from overweight, or who have particularly well-developed muscles such as long-distance athletes. Similarly, armpit chafing can also occur from similar activities and sources. Chafed skin can also result from friction between the skin and clothing. For example, runners often suffer from nipple chafing, which can lead to severe pain and suffering. Chafing can also be prominent in areas with a high degree of moisture, which causes the skin to stick to itself more than when it is dry. Furthermore, sand and other particles which get into clothing or stick to the skin can quickly and easily worsen chafing.
