Ditch cotton. It absorbs sweat and stays wet. Wear synthetic, wicking fabrics.
Cover ’em up. Nipple protection is critical for guys. Band-Aids are common shields.
Get greasy. Apply lubricant to chafe-prone body parts. Petroleum jelly–based products are classic salves. When heading out for a long run, stash ChapStick or a travel-sized deodorant in a pocket.
Hydrate. Drinking minimises the salt concentration of sweat. Salt has a sandpaper effect on skin, says Fayne Frey, M.D., a dermatologist.
Moisturise. “Skin that’s well moisturised – apply lotion twice daily – is less prone to chafing,” Frey says.
Wash up. Shower ASAP after running, keeping water lukewarm. Use antibacterial soap to ward off bacteria that can creep into exposed skin and cause problems like folliculitis, a skin condition that dermatologist Tanya Kormeili, M.D., says occurs in athletes.
Soothe it. Pat – don’t rub – skin dry and apply an ointment such as a nappy-rash cream containing zinc oxide that are antibacterial.
