An oatmeal bath is a surefire remedy for itchy or inflamed skin. Particularly if you’ve received a number of bites, a soak in the tub could be the best solution. Put a cup of oats in a blender, food processor, or coffee grinder, and pulse until ground into a fine powder. Pour the powder into running, warm bath water, evenly distributing the oatmeal throughout the water. Then, take a dip—about 15 to 20 minutes will do—to lock moisture into the skin and alleviate itching.
