10 benefits of a baking soda bath

Baking powder or baking soda is a basic household product that has many different uses, including baking. Adding baking soda to a bath can help detoxify the body, relax muscles better, and nourish your skin. In this article, we look at the benefits of a soda bath and how taking one can help. We also look at other types of detox baths and how to use them.

What is a baking soda bath?

Baking soda has many uses and is a popular home remedy for many ailments. Baking soda is a mixture of sodium ions and bicarbonate ions. It completely dissolves in water and is commonly added to oral care and cleaning products as it can help eliminate bacteria, odors and acids. These properties can also be beneficial for the skin, especially if a person suffers from certain skin conditions. Even without adding baking soda to the water, a hot bath can have valuable therapeutic properties, warming up a person’s muscles and helping them relax after a stressful day. A hot or lukewarm bath can also encourage sweating, which can help the body flush toxins from the pores.

The ten benefits of a soda bath

A baking soda bath can be beneficial in many situations, including:

1. Yeast Infections

Many people suffer from yeast infections, but certain symptoms, such as itching and swelling, can often prevent a person from going about their daily lives. A soda bath can 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.

2. Fungal infections of the skin and nails

Research suggests that baking soda may be a useful antifungal against many strains of fungus that commonly infect human skin and nails. People with onychomycosis, a nail fungus that causes thick, discolored, or brittle nails, can get relief by regularly soaking their hands or feet in a baking soda bath. However, anyone with a yeast infection should ask their doctor if a soda bath can help relieve their symptoms.

3. Eczema

Eczema causes patches of dry, irritated and inflamed skin to appear on the body during flare-ups. These areas can be so itchy that the person scratches and bruises their skin, making them susceptible to infection and worsening symptoms. Baking soda can help prevent eczema flare-ups or relieve symptoms in some people. Adding baking soda to a warm bath can help soothe itchy skin. It is important to pat dry and moisturize skin immediately after bathing.

4. Psoriasis

Like eczema, medicinal baths can be helpful for people with psoriasis. People dealing with psoriasis symptoms often use oatmeal baths to reduce inflammation. Adding 1/2 cup of baking soda to an oatmeal bath can further reduce irritation and itching. It is important for a person with psoriasis to moisturize their skin immediately after toweling off, as hot water can further dry out the skin.

5. stinging plant bites

A baking soda bath can treat skin rashes caused by poison ivy or similar poisonous plants. Baking soda can also help heal rashes caused by contact with stinging plants. Bathing is usually a good idea after touching poisonous plants. Baking soda can soothe inflamed skin and reduce irritation and itching. Soaking in a lukewarm bath with 1 cup of baking soda can help relieve symptoms.

6. Urinary Tract Infection (UTI)

A UTI causes pain and burning when urinating, a condition caused by extra acid in the urinary tract. Although a baking soda bath does not change the acidity of urine, it can reduce pain and discomfort when used along with antibiotics prescribed by a doctor. Add 1/2 cup of baking soda to the bath and let it soak for 15 to 30 minutes.

7. Diaper rash

The moist and warm conditions of a diaper make it the perfect place for germs to multiply. This can lead to a red rash on the skin called diaper rash. The constant friction of the diaper can also irritate the baby’s skin. A baking soda bath can help gently wash away irritating germs and soothe sensitive skin. For babies and young children, it’s important to use a minimal amount of baking soda since dissolved baking soda can be absorbed through the skin. In most cases, using 1-2 tablespoons of baking soda in a small warm bath and soaking the affected area for 10 minutes is sufficient.

8. Chickenpox

The constant itching and irritation caused by chickenpox can feel like torture for many people, especially children. A soda bath can provide the relief they need. Adding 1 to 2 cups of baking soda to a lukewarm bath and soaking for up to 20 minutes, three times a day, can help relieve the person.

9. Irritation of the private part

Some women often suffer from irritation and itching in the intimate area. Adding ¼ cup baking soda to a bath and soaking for 15 to 20 minutes, three times a day, may help relieve symptoms in some women.

10. Constipation and hemorrhoids

A soda bath can help relieve itching and pain caused by constipation or hemorrhoids. Half a cup of baking soda in a warm bath may be enough to relieve symptoms.

How to properly prepare a baking soda bath

Using a body brush to gently exfoliate skin beforehand can make a baking soda bath more effective. To make a baking soda bath, add between 1/2 and 2 cups of baking soda to warm bathwater and stir to dissolve. Once the baking soda is completely dissolved, soak it in the tub for up to 40 minutes. After the bath, dry the skin with a towel and use a natural oil or lotion to moisturize the skin.

Other types of detox baths

There are many other natural ingredients to use in a detox bath, including:

Epsom salt
Apple Cider Vinegar

Sometimes baking soda is added to salt baths to increase the effects, but it’s important to check this with a doctor first.

Other uses of baking soda

When not being used in a bath, baking soda can also be used to:

teeth whitening
exfoliation of the skin
the footbath
relieves dry scalp

in summary

As with any treatment, it is imperative to consult a doctor before using baking soda baths to treat an underlying health condition. Doctors may want to monitor the skin’s response; They may also offer safety tips or recommend other treatments to try. Anyone who does not improve or worsens should see a doctor.
