What Are the Benefits of a Baking Soda Bath, How Do You Take One, and Is It Safe?

Taking a warm bath can help you to relax and unwind. Baths also help to:

  • relieve tension and pain
  • promote perspiration
  • boost circulation
  • encourage healing

Adding baking soda to your bath may have additional benefits, many of which are skin-related. Some of these uses are described below:

Yeast infections

Baking soda baths can soothe and relieve yeast infection symptoms such as:

  • itching
  • burning
  • swelling

Baking soda may also have a positive effect on vaginal pH.

A 2014 study found that baking soda killed Candida cells that lead to yeast infections. Baking soda has also been found to have general antifungal affects.

Diaper rash

If your baby has raw skin from a diaper rash, you can soak the affected area in a baking soda bath three times per day. Do this for only 10 minutes at a time. The baking soda may help soothe the raw skin and promote faster healing. Make sure you pat the area dry completely before putting on a new, clean diaper.

Use only 2 tablespoons of baking soda for babies and young children. Don’t use too much, as baking soda can be absorbed into the body through the skin in a process called alkalosis.
