Inner thighs and chafing in summer
Short answer: When the skin of the inner thighs rubs together in warm weather, it can cause redness and soreness. Longer legs on underwear, soft, breathable fabrics and dry layers help reduce the friction.
Why the inner thighs rub
The inner thighs are two skin surfaces that meet at every step. When the temperature rises and the skin becomes damp, friction increases. Damp skin is more vulnerable and gets irritated faster. It is a common problem in summer and on long walks and is not a sign that anything is wrong. There are several things you can do with your clothing to reduce the problem and make the day more comfortable.
Longer legs on underwear
Underwear with longer legs puts a smooth layer between the skin of the inner thighs, so they do not rub directly against each other. Choose a leg that does not roll up and that stays flat. See Lindbergh. Check that the leg edge does not constrict or leave a groove and that the seams are flat. An edge that is too tight can itself cause friction and discomfort.
Fabrics that let moisture escape
Choose fabrics that are soft and let air and moisture escape. Viscose from bamboo has a smooth surface and can feel cool against the skin in the heat. See bamboo undershirt for men. It is a layer that can keep sweat away from the body, so the rest of the clothing does not get damp. Synthetic fabrics that do not let air through can make the moisture worse. Change clothes if you get wet, and dry the skin with a soft towel.
The top and the layers over it
A T-shirt with some length covers the top of the thighs and can stop the trousers pulling up and down. See bamboo T-shirts for men. Choose a top that does not cling to the body, so air can circulate. A loose T-shirt helps the skin stay dry, so the whole body becomes less damp. In very hot weather a light colour can also help, because it absorbs less heat than a dark one.
Habits that help
Keep the skin clean and dry, especially after exercise. Drink water and take breaks in the shade on hot days. Change underwear if you have sweated a lot, and take a spare pair on long trips. Avoid strongly scented products on irritated skin. If the skin becomes red, stinging or develops sores, talk to your doctor or a pharmacy, as it may need treatment that clothing cannot replace.
Care so the clothing lasts
Wash underwear at 30 to 40 degrees and avoid fabric softener, which can make the fabric less breathable. Hang it up to dry and avoid high heat in the tumble dryer, which can make the elastic brittle. Rotate between several pairs so they have time to dry and rest. When the leg edge loses its elasticity, it is time to replace it, as a slack edge can roll up and create more friction than before.
