Summarize this article:

Your body needs water to kick-start the healing process. As you are recovering from a chafing wound, it’s even more important that you drink at least 8 glasses of water each day. If you exercise or do other strenuous activity, then you may need to drink even more to recover. Run a nice, cold bath. Pour in 2 cups of salts and wait for them to fully dissolve. Sit in the bath for around 15 minutes. The salts will help to clean and dry out your chafing wounds. They will also help you to relax and take your mind off the pain. A breathable fabric, such as cotton, will allow your skin to get enough air to stay dry and heal. Cotton also does not hold moisture against your skin, which will limit bacterial growth. You’ll want your clothing to be loose, so that it won’t stick to any injured areas. For example, instead of wearing a synthetic-fabric nightgown, try out cotton pajamas. If you notice that your skin is chafing and moist, get a towel and gently pat it dry. This is particularly important when caring for folded areas of skin, as moisture in these areas will promote skin breakdown. You can also dry your skin by aiming a blow dryer at it. If you are worried about your damaged skin chafing even further, either tape or roll a non-stick bandage over the skin. Keep the bandage fairly loose and change it every 2 hours or so. Giving your chafed skin the most air time possible is the best option, but a bandage will keep it cleaner.

Summary:
Drink lots of water. Bathe in Epsom salts. Wear loose, cotton clothing. Keep your skin dry. Apply bandages over any open skin.
