When washing, pay special attention to your back, an area particularly prone to folliculitis. Antibacterial soap can also help keep the bacteria count down. Rubbing and Chafing Chafing happens when skin rubs against relatively rough areas like sleeve seams. It may also occur where skin rubs together, as on the inner thighs or underarms. Looser, softer, or sleeveless clothing can help if chafing is caused by fabric irritation.
Blisters occur most commonly on the feet from rubbing between skin and footwear.
Shoes should fit well and be gradually broken in before using them in athletic activities. Use the same drying measures described for athlete's foot, because moisture increases friction between skin and fabric. Wearing a thin pair of socks under thicker, more absorbent socks can also decrease friction. Soft, light, smooth fabric should be worn to avoid jogger's nipples. Bras decrease friction, which probably explains why men have jogger's nipples more than women do.
