  • Burning
  • Swelling
  • Itching

Diaper rash

You probably know how diaper rash can be a major obstacle in a child. If your baby develops these, consider soaking the affected area in a baking soda bath three times a day.

However, consider doing the soaking for a maximum of ten minutes only. You don’t want to expose the baby’s delicate skin to a baking soda bath for long as it can get absorbed into the body.

After the bath, be sure to pat the wet area to completely dry before having on a new diaper.


A baking soda bath can also help to soothe and heal eczema. You are advised to moisturize your skin after a bath when it is still damp.


For people with psoriasis, medicated baths are usually among the first options their doctors will recommend.

Fungal skin and nail infections

A study was done on the antifungal activity of sodium bicarbonate against fungal agents that cause superficial infections.

Urinary tract infection (UTI)

According to a study published by the National Library of Medicine, people with UTIs experience pain and burning while urinating due to the extra acidity in their urinary tract.

According to a study published on PubMed, taking baking soda orally may help with the PH levels and symptoms of people with UTI.

Causing allergic reactions is another common baking soda bath side effects, especially for people with sensitive skin.

Naturally, your skin is slightly acidic. This helps it to fight infections and harmful bacteria. However, you will find baking soda baths irritating and uncomfortable if you have sensitive skin.

It can worsen bad hair days

Another one of the major baking soda bath side effects is damaging your hair. Constant baking soda baths will worsen your bad hair days over time.

This is because your hair, just like your scalp, is slightly acidic. Initially, the baking soda bath will cause your strands to shine, but with time, it will cause frizz, tangles, and breakage.

Reduce your athletic performance

Among the common baking soda side effects to athletes is reduced performance. Absorption of too much baking soda in the body will lead to breathing difficulties, hence a lack of endurance during exercise or sporting activities.

Excessive water loss

If you use too much baking soda in your bath, the sodium can lead to water loss from your body. This can lead to dehydration. Ensure that you don’t use excess amounts of baking soda.

Should you take a baking soda bath?

Speak with your doctor if you have any underlying conditions that can be affected by baking soda. Instead of taking a bath, you can use it for teeth whitening, exfoliation, foot soaks, dry scalp relief, and deodorant.

Avoid baking soda baths if you’re pregnant, have open wounds, have diabetes, have fainting spells, have baking soda allergies, have been drinking or are on benzoate antidepressants.

These conditions can cause harsher baking soda bath side effects.
