Summarize:

Carefully wash the affected area with a mild cleanser and rinse with water. Pat the skin dry with a clean towel. Washing the chafed skin is especially important if you've been exercising or sweating a lot. You'll need to wash away the perspiration before treating the skin. Avoid rubbing the skin hard with a towel. You don't want to further irritate dry, peeling skin. Sprinkle powder over your skin. This should help to reduce your skin's friction. You can use talc-free baby powder, baking soda, cornstarch, or another body powder. The use of talcum powder has been brought into question since some studies show it may be a carcinogen, specifically for women if used in the genital areas. Use any kind of petroleum jelly, body balm, diaper rash cream, or product designed to prevent chafing over the skin to reduce your skin's friction. Several products are specifically designed to prevent chafing for athletes. Once you've applied an ointment, you may want to cover the area with a bandage or sterile gauze pad. If the area is very painful or bleeding, ask your doctor for a medicated ointment. You'll be able to spread it on the area much like petroleum jelly. Cool the chafed skin by applying an ice pack right after you finish exercising or begin to notice irritation. Make sure not to apply ice or an ice pack directly to your skin, since this can further damage your skin. Instead, wrap the ice pack in a towel or cloth and keep it near your skin for 20 minutes. This cooling sensation will give you immediate relief. Spread natural aloe vera gel directly from the plant onto the chafed area. You can also purchase aloe vera, but  make sure it has as few additives as possible. This will calm your skin. You may also want to drop a couple of drops of tea tree oil onto a cotton ball. Then, spread it over your skin. This can fight infection and help your skin heal faster. Create a soothing mixture of 2 cups baking soda and 10 drops of lavender essential oil. Then add this to a running bath of lukewarm water. Avoid soaking in very hot water, which can dry out or further irritate your skin. Soak for at least 20 minutes and then get out and pat yourself dry with a clean towel. You can also make a soothing tea to add to the tub. Boil 1/3 cup of green tea, 1/3 cup of dried calendula (marigold), and 1/3 cup of dried chamomile in 2 US quarts (2,000 ml) of water. Let the tea steep until the liquid cools, then strain it and pour into your tub. Chafed skin can become infected and need medical attention. If you notice an infection or scaly red rash, go see your medical practitioner. You should also see your doctor if the chafed area is incredibly painful or debilitating and sensitive.
Clean the area. Apply powder. Apply an ointment. Apply ice packs. Apply soothing gels or oils. Take a soothing bath. Know when to see a doctor.
