What is a bleach bath for eczema?

Bleach is a chemical solution that is widely used for cleaning and disinfecting purposes. It is commonly made up of sodium hypochlorite (NaOCl) and water, although there are various types of bleach available on the market, such as hydrogen peroxide and chlorine bleach. In bleach baths, sodium hypochlorite is the primary ingredient used to treat eczema symptoms.

Most of the current treatments for atopic dermatitis have limited effectiveness, negative side effects, or are expensive. Among the activities supporting the treatment of atopic dermatitis, hypochlorite baths deserve special attention. You can easily make a bleach bath at home.

The history of bleach bath

The history of bleach goes back centuries, with early references to the use of chlorine for cleaning and disinfecting dating back to the 1700s. However, the specific use of bleach baths for medical purposes, particularly in the treatment of eczema, is a more recent development. The concept of using bleach to treat skin conditions like eczema was first introduced during World War I, when soldiers were given bleach baths to prevent infection of battlefield wounds. 

The topic may have gained traction in 2009, when a study published in the journal Pediatrics suggested that bathing in a diluted bleach solution could help relieve the symptoms of atopic dermatitis.

They found that bleach baths could be an effective way to reduce the severity of atopic dermatitis and manage the symptoms of eczema.

Why bleach baths work for eczema?

One of the challenges of managing eczema is that it can often lead to secondary infections, particularly from bacteria like Staphylococcus aureus. According to research, individuals with eczema have a higher risk of developing staph infections compared to those without the condition.  

Staphylococcus aureus infection is related to the pathogenesis of eczema and atopic dermatitis. In fact, up to 90% of individuals with moderate-to-severe eczema have been found to carry the bacteria Staphylococcus aureus on their skin. Staph infections are a common complication of eczema, and they can make it harder to manage the condition. In some cases, staph infections can cause the eczema to become more severe and difficult to control.

Staph infections can also cause additional skin symptoms like crusting, oozing, and painful lesions. Bleach baths are one method that can be used to reduce the risk of staph infections in individuals with eczema, by decreasing the number of bacteria on the skin and preventing further infection.

Properties of sodium hypochlorite (NaOCl)

Sodium hypochlorite has antibacterial and anti-inflammatory properties that help to reduce the number of harmful bacteria on the skin and calm inflammation, respectively. By soaking in a bleach bath, these properties can help to alleviate the symptoms of eczema and promote healthy skin.

Bleach bath – is it safe?

It is a completely safe method of atopic dermatitis treatment, provided that we maintain the appropriate concentration of sodium hypochlorite in the water.

The second factor affecting safety is the temperature of the water. Water that is too hot causes the sodium hypochlorite chemical to break down faster and become airborne, which can irritate the respiratory system.

In addition, make sure that the bleach bath takes place in a bathroom that has a window or adequate ventilation. Exposure to the smell of bleach can make asthma worse.

Are bleach baths safe for babies with eczema?

Bleach baths should be used with caution for babies with eczema. It is best to consult with a pediatrician or dermatologist before trying bleach baths for babies. Alternative options, such as moisturizing and gentle cleansing, may be more appropriate for baby’s delicate skin.
