For people with skin conditions such as atopic dermatitis or psoriasis, hot springs are neither something that always works nor something that should always be avoided. Whether they suit you varies greatly from person to person. In short, the Ministry of the Environment’s framework includes skin-related conditions among the indications for some spring types, and Japan has a long tradition of skin-focused hot spring therapy. However, this does not mean hot springs can cure disease, and depending on the spring type and how you bathe, they may even worsen symptoms.
That is why the key is to approach them cautiously: do not expect too much, avoid strongly irritating waters, start with a short soak, moisturize promptly after bathing, and stop if they do not suit you. If you do try them, they should never replace dermatological treatment. They should be used only as a complement, after consulting your primary doctor. This article offers a neutral overview, based on the Ministry of the Environment’s public framework, of how people with skin conditions can approach hot springs.
This article is general information and not medical advice. If you have atopic dermatitis, psoriasis, chronic eczema, or another skin condition, do not use hot springs as a substitute for treatment. Be sure to ask a dermatologist whether bathing is appropriate and how to do it safely. The indications mentioned below are based on the Ministry of the Environment’s framework and do not guarantee any therapeutic effect. Results and compatibility vary widely from person to person. If you have itching, redness, oozing, infection, or worsening symptoms, avoid bathing and seek medical care. If your doctor has given you specific bathing instructions, follow those first.
First, it helps to understand the public framework. In Japan, the Ministry of the Environment designates certain hot springs that meet specific standards as therapeutic springs, and each therapeutic spring has listed indications. These are symptoms or conditions that the spring is considered suitable for. There are general bathing indications shared by all therapeutic springs, as well as spring-type-specific indications.
Within this framework, some spring types include skin-related conditions. For example, spring-type-specific indications for chloride springs, sulfate springs, and sulfur springs may list conditions such as atopic dermatitis, psoriasis vulgaris, chronic eczema, and pyodermic skin disorders. In practice, Japan has long had a tradition of skin-focused hot spring therapy, with people staying for extended periods at hot spring resorts to help with skin problems.
What must be stressed, however, is that these indications are only part of the Ministry of the Environment’s framework. They are not proof that a hot spring will definitely cure anything. The indications for therapeutic springs are based on repeated use over a certain period of time; they cannot be judged from a single bath. For a fuller explanation of the idea of hot spring therapy, see What Is Toji?. Even with the same skin condition, whether a hot spring suits you can change greatly depending on the severity and timing of symptoms. So do not assume, simply because it is listed as an indication, that it will work for you personally.
Another important point is that even among spring types said to be related to skin conditions, some can be too irritating for sensitive skin. In particular, acidic springs and sulfur springs should be handled with care.
The Ministry of the Environment also defines contraindications for each spring type. For acidic springs and sulfur springs, these include people with sensitive skin or mucous membranes, and skin dryness in older adults. In other words, these strong spring types can be relevant to skin conditions as indications, while also being unsuitable for people with sensitive skin. The same spring type may suit one person but be too strong for another. The nature of acidic springs is explained in What Is an Acidic Spring?, and sulfur springs are explained in What Is a Sulfur Spring?.
In practice, strongly acidic water can sting or burn, and if the skin barrier is already weakened, it can become a burden. The idea of choosing a strongly irritating bath because it is said to help the skin may actually backfire. If you have a skin condition and feel uneasy, it is safer to start with a spring type considered gentle and try it only for a very short time. Not every spring type will suit every person, so the final judgment should be left to a dermatologist. The overall concept of contraindications is summarized in Onsen Contraindications Guide.
For people with skin conditions, spring type is not the only thing that matters. Even in the same bath, the temperature, bathing time, washing method, and post-bath care can greatly affect the burden on the skin. These are things you can adjust yourself, regardless of facility or spring type, and they are key to reducing strain when you are unsure which spring to choose. The table below summarizes the main points and countermeasures.
| Aspect | Why it can be a burden | Countermeasure (guideline, varies by person) |
|---|---|---|
| Spring type | Strongly irritating waters such as acidic or sulfur springs can burden sensitive skin | Choose gentler water. Avoid strong waters or try them only briefly |
| Temperature | Hot water can trigger itching and increase dryness | Choose lukewarm water and avoid hot baths or long soaks |
| Bathing time | The longer you soak, the more skin oils are removed, which can lead to dryness and itching | Keep it short and take breaks to check how your skin feels |
| Washing and drying | Rubbing can damage the skin barrier and trigger worsening | Do not scrub with a nylon towel. Pat dry gently |
| Post-bath care | Skin dries quickly after bathing, leading to tightness and itching | Moisturize promptly after bathing |
| When symptoms worsen | Bathing with oozing, infection, or severe itching can make things worse | Do not force it. Skip bathing and seek medical care |
Among these, temperature, bathing time, washing, and post-bath care are things you can manage anywhere. In particular, hot water and long soaks can worsen both itching and dryness, so the basic rule is to bathe briefly in lukewarm water.
For people with skin conditions, how you wash and dry yourself is just as important as choosing the spring type. Scrubbing hard with a nylon towel or body brush can damage the skin’s surface barrier and easily worsen itching and eczema. Habits like rubbing hard to remove dirt or exfoliate are especially harsh on sensitive skin.
When washing, the basics are to use your hands or well-lathered cleanser and avoid strong friction. When drying with a towel after bathing, do not rub hard; gently press to remove moisture. Just following this one rule, “do not rub,” can make a big difference in how much strain the skin experiences. Even if you choose a gentle spring, it will not help if your washing or drying habits injure your skin.
For people with skin conditions, care continues after you leave the bath. When bathing removes skin oils and dead skin cells, the skin can dry out more quickly afterward, leading to tightness and itching. Baths that make the skin feel especially smooth can also mean that more oil has been removed, which increases dryness. Since dryness can trigger itching, and scratching can make it worse, moisturizing is essential.
That is why the basic rule is to moisturize as soon as possible after bathing. Leaving the skin unprotected because you want to keep the spring’s minerals on your skin can actually increase dryness. If you normally use a prescribed moisturizer, it is wise to bring it with you when traveling so you can keep up your usual care. The relationship between hot springs and skin, and the mechanism behind post-bath dryness, is also explained in The Science of Hot Springs and Skin Beauty. Enjoying the comfort of hot springs and protecting your skin are best considered together.
For people with skin conditions, it is usually better to start with a very short soak and see how the skin reacts, rather than staying in for a long time from the beginning. This is especially true for water considered strong or hot water. A safer approach is to bathe briefly, get out, and if everything seems fine, enter again briefly. Since skin compatibility is not always clear after one try, it can also be practical to keep the first day conservative and, if there are no problems, observe a little more the next day.
If you feel stinging, increased itching, redness, or a strong tightness during or after bathing, do not continue. Get out and stop if it does not seem to suit you. The last thing you want is to keep forcing yourself to stay in just because you came all this way. Also, if the affected area is oozing or infected, or if symptoms are worsening, please avoid bathing altogether and seek medical care. In public baths, it is also better from a hygiene standpoint to wait until the condition has settled. For general guidance on choosing and using hot springs with sensitive skin, see Choosing an Onsen for Sensitive Skin.
Even when hot springs are part of how you manage a skin condition, they are not a substitute for dermatological treatment. Atopic dermatitis and psoriasis require ongoing treatment and management, so it is more realistic to think of hot springs as a supporting measure. Do not stop prescribed topical medications or treatment on your own and rely on hot springs instead.
If you plan to incorporate hot springs as part of a longer stay for therapy, it is reassuring to consult your dermatologist beforehand about whether you are in a condition that allows bathing and what frequency or duration would be reasonable. If your doctor has given you instructions about bathing, follow those first. With the understanding that results and compatibility vary greatly from person to person, the basic approach is to stop if it does not suit you and to ask for advice if you are concerned.
It cannot be said definitively that they help. Under the Ministry of the Environment’s framework, some spring types list atopic dermatitis among their indications, but this does not guarantee a therapeutic effect, and compatibility varies widely from person to person. Strongly irritating water can even make symptoms worse. Do not use hot springs as a substitute for treatment, and ask a dermatologist whether bathing is appropriate and how to do it.
It depends greatly on the person, the severity of symptoms, and the timing, so there is no single yes-or-no answer. Some spring-type-specific indications include psoriasis vulgaris, but that does not mean the spring is right for you. Do not rely on your own judgment alone. Consult a dermatologist, and if you do try it, start briefly and stop if it does not suit you.
Caution is needed. Acidic springs and sulfur springs may list skin-related indications, but the Ministry of the Environment’s spring-type contraindications also include people with sensitive skin or mucous membranes and skin dryness in older adults, so they can be strongly irritating and may worsen symptoms. See What Is an Acidic Spring? and What Is a Sulfur Spring? for details, and avoid them or limit yourself to a very short soak if you are unsure.
When bathing removes skin oils and dead skin cells, the oils that protect the skin are also lost more easily, so dryness and tightness can progress after bathing and itching can become more likely. Hot water and long soaks intensify this tendency. Bathing briefly in lukewarm water, avoiding friction, and moisturizing promptly after bathing can help reduce the burden. For the mechanism, see The Science of Hot Springs and Skin Beauty.
Bathing with oozing or infected areas can sting or worsen symptoms, and in public baths there are also hygiene concerns. Do not force it. Skip bathing, wait until the condition settles, or seek medical care and decide based on that advice.
