People with atopic dermatitis (eczema) can often struggle with finding the right products or lifestyle habits that work best to manage the skin condition they deal with on a regular basis. Generally speaking, people tend to figure out what works best for them over time, but it is possible that certain remedies may provide relief at one point in time and then work poorly at other times, or vice versa. 

Within the eczema community, hygiene is a common topic of discussion. Ideal bathing habits can be especially difficult for people with eczema to determine because no technique works for everyone, and each method of cleanliness can affect these patients in different ways. The length of time, the purpose, the products used during or after, and even the water itself may influence the symptoms. 



Bathing is often more than just cleanliness. Even the purpose of bathing can be much more than one would initially think by considering the psychological connections to eczema. Emotional stress and anxiety are associated with itch and flares in people with eczema,[1-3] so if the purpose and result of the bath are stress reduction, it is possible that these people may receive more benefits from bathing than simply cleansing.


Bathing Habits

How often, for how long, and at what temperature should one with eczema bathe? The answer is that those factors should be tailored to each individual, but there are some general patterns to consider. Two studies found that the severity of the condition is not related to the frequency of bathing,[4,5] but may be associated with a longer duration of bathing.[4] Higher temperatures affect eczema too. Water set to 113 degrees F (similar to a very warm bath or shower) can worsen itching in those with eczema.[6]

On the other hand, short baths in warm mineral-rich water may be helpful. Researchers showed that a twice daily, 10-minute soak in a hot spring bath that was 107 degrees F improved skin symptoms in 76% of patients with eczema.[7]


Bath Products

The products used in or during the bath can also make a difference. This can include products used on the skin when in the bath, as well as the products added to the bath itself. 

The products used on the skin can have dramatic effects on the symptoms of eczema. Some people can be sensitive to the dyes, fragrances, and scents that are added to some products.[8] A study found that hand washing practices showed that the group using soap had the largest worsening in symptoms, followed by high pH solutions, then sanitizer.[9] An evaluation of general hygiene habits found that patients with eczema are more likely to use bath oils than soap because the bath oils may be gentler on the skin.[10] 

The products used in the water can also improve or worsen the symptoms of eczema. A common product used in baths by patients with eczema is a small amount of chlorine bleach in the water to create a dilute bleach bath. Chlorine is the base for most types of bleach. A randomized, placebo-controlled study found that patients with eczema who soaked in a dilute bleach bath for 10 minutes twice per week showed a significant reduction in symptoms.[12] 

Bath salts, like those found in Epsom salt (magnesium sulfate) and the magnesium-rich dead sea salts, can improve water loss, skin hydration, and redness in patients with eczema.[13]

Essential oils are commonly added to bath water for many reasons, but they can have the potential to help or harm, depending on the essential oil. Certain essential oils like lavender, for example, carry a higher risk to cause skin allergies,[8] while others can be very soothing. Oils of Retama raetam, Artemisia princeps, and Matricaria recutita can all reduce itchiness.[14]


The Water

The water used for the bath may make a difference in eczema symptoms and possibly even change the chances of developing eczema later in life. Exposure to hard water early in life may increase the risk of developing childhood eczema later in life,[15,16] though water softeners do not necessarily provide any additional benefit to those who already have eczema.[17]

In conclusion, bathing can play a role in eczema in many different ways. Each bathing approach should be evaluated on an individual level, as the results of each treatment can vary between patients.
