According to the Mayo Clinic, skin friction occurs when the skin is resistant to motion, which in turn can lead to bedsores and skin injury. Skin friction is a common reaction to the skin being dragged across surfaces. Skin friction is typically more severe when the skin is moist.
WebMD explains that continual skin friction can lead to chafing: This irritation of the skin typically occurs in between the thighs and under the arms, but can develop anywhere on the body. The severity of skin chafing ranges from mild irritation to painful, crusted sores that require medical attention. Skin chafing can be prevented by decreasing friction to the skin. Skin friction prevention measures include: keeping the skin dry with talcum powder and wearing clothes made from synthetic materials.
