Whip up a simple bath with 1 cup (129 g) of colloidal oatmeal. Fill your tub with lukewarm water, then sprinkle in the colloidal oatmeal. Relax and unwind for about 15 minutes, which can help relieve your itchy skin. When soaked in water, oatmeal does a great job of sticking to your skin, which helps protect and soothe your skin.^{[4]

Fill your tub with lukewarm water and mix in ⅓ to 1 cup (43-129 g) of ground oatmeal. Stir the powdered oatmeal into the bath water until it looks milky, and coax your furry friend into the tub. Gently ladle the bath water over your dog’s fur and skin, waiting 10 minutes for the oatmeal to really soak in. Rinse off the leftover oatmeal with warm water until your pet’s fur and skin is completely clean. Then, guide your pooch out of the tub and towel-dry them off.
- Small dogs only need about ⅓ cup (43 g) of colloidal oatmeal in the bath, while bigger dogs might need ½ to 1 cup (65-129 g).
- If your dog still seems itchy after the bath, call your vet for advice.

Fill up your tub with lukewarm water and mix in the colloidal oatmeal. Stir the powder into the bath water and soak for about 10-15 minutes. Towel-dry yourself off as you step out of the bath, so your skin is damp but not dripping wet. Then, rub your moisturizer of choice into your skin right after.
- A nice soak in an oatmeal bath can help loosen some of the psoriasis “scales” on your skin.^{[7]

Give yourself temporary relief by soaking in a lukewarm bath. Yeast infections can leave you with an overwhelming itch and burning feeling that just won’t go away. While it’s best to tackle yeast infections at the source, an oatmeal bath can give you some relief from the more obvious symptoms.

Enjoy a 20-30 minute oatmeal when you have chicken pox. Cool or lukewarm water can help soothe away the itch—it’s really up to your personal preference. Since chicken pox tends to flare up all over, give yourself 20-30 minutes to soak instead of the usual 15-minute bath.
- If you plan on washing up during your oatmeal bath, choose a mild soap that won’t irritate your skin even more.
- Pat your skin dry after the bath instead of rubbing it.

Take quick oatmeal baths to cope with the itchiness. Poison ivy, sumac, or oak rashes are no fun, especially if they’re all over your skin. Soak in the tub for a few minutes and see if the oatmeal helps relieve any of the itchiness.^{[12]

Cancer treatments can really ravage your skin with unpleasant side effects. You may notice unexplained rashes, or feel like your skin is sunburned. Add some colloidal oatmeal to your bath to help ease away these unpleasant symptoms. Lukewarm or cool water is best for these kinds of baths.
- Always talk to a doctor if you’re dealing with any unexplainable side effects from your treatment.
