Baking soda is a household staple with many different uses. Adding a quarter cup of baking soda to a lukewarm bath and soaking for up to 30 minutes may relieve itching, irritation, or infections or just provide a detox.
Adding baking soda — also known as sodium bicarbonate — to a bath may help with a range of conditions, such as:
This article looks at the benefits of a baking soda bath and how taking one may help. We also examine some other types of detox baths and their uses.
Baking soda is a mixture of sodium ions and bicarbonate ions. It dissolves fully in water, and people commonly add it to oral hygiene and cleaning products as it may help remove bacteria, odors, and acidity.
These properties may also be helpful for the skin, especially if a person has certain skin conditions.
Even without adding baking soda to the water, soaking in a warm bath may have valuable therapeutic properties by warming a person’s muscles and helping them relax after a stressful day.
A warm or hot bath can also promote sweating, which may help the body release toxins from the pores.

A baking soda bath can be beneficial for many conditions, including:
Many people experience yeast infections, but some symptoms, such as itching and swelling, can often make it difficult for a person to go about their daily activities. A baking soda bath may relieve symptoms and help a person recover faster.
One study found that baking soda helped kill Candida cells, the fungal cells responsible for yeast infections.
Research suggests that baking soda may be useful as an antifungal agent against many fungal strains that commonly infect human skin and nails.
People with the nail fungus onychomycosis, which causes thick, discolored, or crumbly nails, may find relief from regularly soaking their hands or feet in a baking soda bath.
However, anyone with a fungal infection should ask their doctor if a baking soda bath can help relieve symptoms.
Eczema causes dry, itchy, and inflamed patches of skin to develop on the body during flare-ups. These areas may be so itchy that a person scratches and breaks the skin, leaving it prone to infection and making symptoms worse.
Baking soda may help prevent eczema flare-ups or reduce symptoms in some people. Adding a quarter cup of baking soda to a warm bath may help soothe itchy skin.
It is important to pat the skin dry and moisturize immediately after the bath.
There is evidence that baking soda baths can be helpful for people with psoriasis. People managing psoriasis symptoms may also use oatmeal baths to reduce inflammation.
Adding both baking soda and oatmeal to a bath may reduce irritation and itchiness.
It is essential to moisturize the skin immediately after drying off with a towel, as hot water can dry out the skin further.
Baking soda may also promote the healing of rashes caused by touching poisonous plants.
Taking a bath is a good idea after touching toxic plants as bathing can wash off the oils that cause a rash, reducing the amount the skin absorbs.
A bath may also help prevent these oils from spreading to other areas of the body or another person.
Baking soda can soothe inflamed skin and reduce irritation and itching. Soaking in a lukewarm or cool tub with baking soda may help reduce symptoms. Adding oatmeal to the bath can also ease itching, as can applying cool compresses.
A UTI causes pain and burning while urinating due to extra acidity in the urinary tract.
Although a baking soda bath will not change the acidity of the urine, it may reduce pain and discomfort when used alongside doctor-prescribed antibiotics.
Research suggests taking baking soda by mouth may also help improve pH levels and symptoms in people with a UTI.
Is a baking soda bath beneficial for people with a urinary tract infection?
Diapers are damp and warm, making them the perfect place for pathogens to multiply.
This can result in a red rash on the skin called a diaper rash. Constant friction from the diaper can also irritate the skin.
A baking soda bath can help remove the pathogens that cause irritation and soothe sensitive skin.
For babies and small children, it is essential only to use a minimal amount of baking soda, as the skin can absorb dissolved baking soda.
For severe diaper rash, a person should add 2 tablespoons of baking soda to a warm bath and soak the affected area for 10 minutes, three times per day. After soaking, they should apply a topical antiyeast ointment. A doctor can recommend a suitable preparation.
