Chafing is a skin condition that occurs when you have repeated skin-on-skin contact or when your skin rubs against clothing or another material. Common causes include intense exercise, ill-fitting clothes, excess skin and hot weather. Prevention includes wearing appropriate clothing and using anti-chafing products or petroleum jelly.

Chafing is a common skin problem caused by any combination of friction, moisture, and irritating fabric. Prolonged rubbing on the skin makes your skin sting or burn, and you develop a mild, red rash. In severe cases, chafing will include swelling, bleeding, or crusting.

Chafing is more likely to occur in particular areas of the body, and it tends to happen during physical activity, such as running. Others causes of chafing include: sweating breastfeeding wearing tight clothes participating in an endurance sport, such as a marathon

Some notable causes of the condition include: Endurance exercise: Repeat motions involved in biking or running may lead to friction, while sweat can worsen the friction.   Weight: For people who are overweight or obese, skin folds and chafing occur more regularly.
