Chafing is skin irritation that occurs where skin rubs against
skin, clothing, or other material. Skin irritation from rubbing
When skin becomes irritated because of something rubbing, there
are several things you can try, including: Avoid coarse
clothing. Wearing 100% cotton fabric against your skin may help.
Eliminate friction against your skin by using appropriate
clothing for the activity you are involved in (for example,
athletic tights or cycling shorts). Avoid activity that is
causing chafing unless it is part of your typical lifestyle,
exercise routine, sporting, or other activity. Wear clean and
dry clothing. Dried sweat, chemicals, dirt, and other debris may
actually be causing the irritation. Temporarily use petroleum
jelly or baby powder on chafed areas of your skin. You can also
use these agents before activity to prevent chafing in easily
irritated areas -- for example, your inner thighs or upper arms
while running. Mailler-Savage EA, Adams BB. Skin manifestations
