What Is Halotherapy (Salt Therapy)?
What halotherapy (salt therapy) is, how it works, what it is used for, the evidence behind it, and its place in wellness and recovery.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Halotherapy, also known as salt therapy, is a wellness practice in which a person breathes air containing tiny particles of salt, usually while relaxing in a room or booth designed to resemble a salt cave (a salt room). The idea is that inhaling these fine, dry salt particles may help the airways and skin: proponents suggest it can help clear mucus, reduce inflammation, and ease breathing in respiratory conditions such as asthma, bronchitis, and allergies, and may improve certain skin conditions. It is generally relaxing and is often used as a calming, restorative wellness experience. It is important to understand that halotherapy is considered a complementary or wellness therapy rather than a proven medical treatment: while some people report benefits and there is limited supporting research, the scientific evidence is not strong or conclusive, and halotherapy should not replace medical treatment for any condition. It is generally regarded as safe for most people, though those with certain conditions should check with a doctor first. In a wellness or recovery setting, halotherapy may be offered as one of several relaxing, supportive activities that promote calm and wellbeing, alongside, not instead of, proper medical and therapeutic care.
What is halotherapy?
Halotherapy, commonly known as salt therapy, is a wellness practice in which a person breathes in air containing very fine, dry particles of salt. The name comes from halos, the Greek word for salt. Typically, halotherapy takes place in a specially designed salt room or salt booth, often built to resemble a salt cave, with salt-covered surfaces and a device called a halogenerator that grinds salt into microscopic particles and disperses them into the air. The person relaxes in the room, usually seated comfortably, for a set period (often around 30 to 45 minutes), breathing in the salt-infused air. The practice is inspired by the historical observation that people who spent time in natural salt caves or salt mines sometimes reported respiratory benefits, and modern halotherapy aims to recreate a similar environment in a controlled, comfortable setting. Halotherapy is generally experienced as calming and relaxing, and it is offered in spas, wellness centres, and some health and recovery settings.
This article explains what halotherapy is, how it is thought to work, what it is used for, the evidence behind it, and its place in wellness and recovery. The central message is that halotherapy is a wellness or complementary practice, valued by many for its relaxing, restorative qualities and suggested to offer some benefits for the airways and skin, but that it is not a proven medical treatment, and the scientific evidence for its benefits is limited and not conclusive. It should therefore be seen as a potentially pleasant, supportive wellness activity rather than a substitute for proper medical care. Understanding what halotherapy is, and its limitations, helps people approach it with realistic expectations. In a wellness or recovery context, such as a supportive, holistic environment, halotherapy may feature as one of several calming activities that promote relaxation and wellbeing, always alongside, and never instead of, appropriate medical and therapeutic treatment.
How halotherapy works and what it is used for
The idea behind halotherapy is that inhaling fine, dry salt particles may have beneficial effects on the airways and, in some approaches, the skin. Salt (sodium chloride) has properties that proponents suggest could help the respiratory system: it is thought that the tiny inhaled salt particles may help to thin and loosen mucus in the airways, making it easier to clear, may have anti-inflammatory effects that could reduce swelling in the airways, and may help to reduce irritation, potentially easing breathing. On this basis, halotherapy is used and promoted for a range of respiratory conditions, including asthma, chronic bronchitis and other chronic lung conditions, allergies and hay fever, sinus problems, and general respiratory wellness, with the aim of helping breathing and reducing symptoms. Some forms of halotherapy, or related salt treatments applied to the skin, are also suggested to help certain skin conditions, such as eczema, psoriasis, and acne, by drawing on salt’s properties.
Beyond these suggested physical effects, halotherapy is widely valued for its relaxing and stress-relieving qualities. Sitting quietly in a calm, spa-like salt room can be a soothing, restorative experience, and many people find it helps them relax, unwind, and de-stress, which is a benefit in itself for general wellbeing. It is important, however, to distinguish between these two aspects: the relaxation and sense of wellbeing that halotherapy provides are widely experienced and valued, whereas the specific medical claims about treating respiratory and skin conditions are less well established. Halotherapy comes in dry forms (the salt-room approach described here) and there are related salt-based practices, and the exact methods and claims can vary between providers. Understanding what halotherapy is used for helps set expectations: it is often sought both for possible respiratory or skin benefits and, very commonly, simply for relaxation and wellness.

The evidence and its place in wellness and recovery
An important and honest point about halotherapy is that it is considered a complementary or wellness therapy rather than a proven medical treatment, and the scientific evidence for its specific health benefits is limited and not conclusive. While some people report that halotherapy helps their breathing or symptoms, and there is some research and a long tradition behind the idea, the studies are generally limited, of varying quality, and not sufficient to firmly establish that halotherapy effectively treats conditions such as asthma or other respiratory or skin diseases. This means that halotherapy should be approached as a potentially pleasant and possibly helpful wellness practice, but not as a substitute for proven medical treatments. Crucially, anyone with a medical condition such as asthma or another respiratory or skin condition should continue their prescribed medical treatment and should not replace it with halotherapy or stop their treatment in favour of it; halotherapy might, at most, be used as a complementary addition, and only after discussing it with their doctor.
Halotherapy is generally regarded as safe and low-risk for most people, since it mainly involves relaxing and breathing salt air. However, some people should be cautious or check with a doctor first: for example, people with certain conditions might find inhaled salt irritating, and anyone with a significant respiratory or other health condition should seek medical advice before trying it, stopping if it causes irritation such as coughing. In a wellness or recovery setting, such as a holistic, supportive environment that cares for the whole person, halotherapy may be offered as one of several calming, restorative activities, alongside things like relaxation, mindfulness, gentle exercise, and other wellness practices, that help promote relaxation, reduce stress, and support overall wellbeing. In such a setting, the main value of halotherapy is often its relaxing, soothing quality and its contribution to a sense of calm and self-care, which can be genuinely beneficial as part of a supportive experience, particularly for people focusing on their wellbeing and recovery. The key point is that such wellness activities complement, but never replace, the core medical, psychological, and therapeutic treatment that addresses a person’s health or recovery. The key messages are that halotherapy (salt therapy) is a wellness practice of breathing salt-infused air, valued especially for relaxation and suggested to offer some respiratory and skin benefits, that it is a complementary therapy with limited scientific evidence and not a proven medical treatment, that it should not replace medical care, and that in a wellness or recovery context it can be a pleasant, supportive activity alongside proper treatment.

Halotherapy, also known as salt therapy, is a wellness practice in which a person breathes air containing tiny particles of salt, usually while relaxing in a room or booth designed to resemble a salt cave (a salt room). The idea is that inhaling these fine, dry salt particles may help the airways and skin: proponents suggest it can help clear mucus, reduce inflammation, and ease breathing in respiratory conditions such as asthma, bronchitis, and allergies, and may improve certain skin conditions.

In a wellness or recovery setting, halotherapy may be offered as one of several relaxing, supportive activities that promote calm and wellbeing, alongside, not instead of, proper medical and therapeutic care.
As Dr. Ponlawat Pitsuwan, addiction medicine specialist at Phuket Island Rehab, puts it, “I am asked about halotherapy quite often, and my answer tries to hold two things in balance. On one hand, sitting quietly in a calm salt room, breathing slowly, letting your shoulders drop, is genuinely relaxing, and relaxation and stress relief are real, valuable things, especially for people in recovery. On the other hand, I am careful never to let anyone believe it treats their asthma or replaces their inhaler or their medication, because the evidence simply is not there for that. So I frame it honestly: enjoy it as a soothing wellness experience, one of many calming activities that support wellbeing, but keep taking your real treatment, and check with your doctor if you have a lung condition.”
Frequently asked questions
What is halotherapy used for?
Halotherapy (salt therapy) is used and promoted for two broad purposes. First, for possible respiratory and skin benefits: proponents suggest that breathing fine, dry salt particles may help the airways by thinning and loosening mucus, reducing inflammation, and easing breathing, and on this basis it is used for respiratory conditions such as asthma, chronic bronchitis and other lung conditions, allergies and hay fever, and sinus problems, as well as, in some forms, for certain skin conditions like eczema, psoriasis, and acne. Second, and very commonly, halotherapy is used simply for relaxation, stress relief, and general wellbeing: sitting quietly in a calm, spa-like salt room is a soothing experience that many people find restorative. It is important to note that while the relaxation benefits are widely experienced, the specific medical claims for treating respiratory and skin conditions are not strongly supported by scientific evidence, so halotherapy should be seen as a wellness practice rather than a proven treatment, and should not replace medical care for any condition. Many people seek it both for possible symptom relief and, especially, for its calming, wellness qualities.
Does halotherapy actually work?
The honest answer is that halotherapy’s benefits are not firmly established by strong scientific evidence, so whether it works depends on what is meant. For relaxation and stress relief, halotherapy does seem to help many people: the calm, spa-like experience of sitting quietly in a salt room is genuinely soothing and restorative for a lot of people, and this wellbeing benefit is real and valued. For specific medical claims, such as treating asthma or other respiratory or skin conditions, the evidence is limited and not conclusive: while some people report that it helps their breathing or symptoms, and there is some research and a long tradition behind the idea, the studies are generally limited and of varying quality, and they are not sufficient to firmly establish that halotherapy effectively treats these conditions. So halotherapy is best regarded as a complementary or wellness practice that many find relaxing and that may offer some benefit for some people, but not as a proven medical treatment. Anyone with a medical condition should not rely on halotherapy in place of proper treatment, should continue their prescribed care, and should discuss with their doctor before using halotherapy as a complementary addition. Approaching it with realistic expectations, mainly as a relaxing wellness experience, is sensible.
Is halotherapy safe?
Halotherapy is generally regarded as safe and low-risk for most people, since it mainly involves relaxing in a room and breathing air containing fine salt particles, which is non-invasive and gentle. Most people can enjoy it without problems. However, there are some cautions. Some people may find the inhaled salt mildly irritating, and it can occasionally cause a cough or throat irritation; if this happens, it is sensible to stop. People with certain conditions should be cautious and check with a doctor before trying halotherapy, particularly those with significant respiratory conditions (such as severe asthma or other lung diseases), certain infections, or other health concerns, to make sure it is appropriate for them. Because halotherapy is a wellness practice and not a regulated medical treatment, standards can vary between providers, so choosing a reputable provider is wise. Importantly, safety also means not relying on halotherapy in place of proper medical treatment: it should never replace prescribed care for a medical condition. For most healthy people seeking relaxation, halotherapy is a safe and pleasant experience, but if you have a health condition, it is best to check with your doctor first, and to stop and seek advice if it causes any irritation or discomfort. As with any wellness practice, listening to your body and using common sense is important.
Can halotherapy replace medical treatment for asthma or other conditions?
No, halotherapy should not replace medical treatment for asthma or any other condition. This is a very important point. Halotherapy is a complementary or wellness practice with limited scientific evidence for treating medical conditions, whereas asthma and other respiratory or skin conditions have established, effective medical treatments that are important for controlling the condition and preventing serious problems. For someone with asthma, prescribed treatments (such as inhalers) are essential, and stopping or replacing them with halotherapy could be dangerous, potentially leading to worse symptoms or serious asthma attacks. At most, halotherapy might be used as a complementary addition to proper medical treatment, and only after discussing it with a doctor, who can advise whether it is appropriate for the individual. The relaxation and wellbeing that halotherapy provides can be a nice complement to medical care, but they are not a substitute for it. So if you have a medical condition, continue your prescribed treatment, keep up with your doctor’s advice, and treat halotherapy purely as an optional, complementary wellness activity, not as a replacement therapy. Anyone considering using halotherapy alongside their treatment for a health condition should talk to their doctor first. Relying on unproven therapies in place of proven medical care can be harmful, which is why this distinction matters so much.
What is a salt room or salt cave?
A salt room or salt cave is the specially designed space in which halotherapy usually takes place. It is a room or booth built to create a salt-rich, cave-like environment, often with walls, floors, or features covered in salt (such as salt bricks or loose salt), soft lighting, and comfortable seating, designed to feel calm, relaxing, and spa-like. The key functional element is usually a device called a halogenerator, which grinds salt into microscopic dry particles and disperses them into the air of the room, so that people relaxing inside breathe in the salt-infused air. The design is inspired by natural salt caves and salt mines, where people historically reported respiratory benefits from the salty air, and modern salt rooms aim to recreate a similar environment in a controlled, comfortable, indoor setting. People typically sit in the salt room for a session of around 30 to 45 minutes, relaxing while they breathe the air. Salt rooms are found in spas, wellness centres, and some health and recovery settings. The environment itself contributes to the experience: the quiet, soothing, cave-like atmosphere is a big part of why halotherapy feels relaxing and restorative, which is one of its main appeals. It is worth remembering that, as with halotherapy generally, the salt-room experience is a wellness practice rather than a proven medical treatment.
Does halotherapy have a role in recovery or wellness programs?
Halotherapy can have a role in wellness and recovery programs as one of several supportive, relaxing activities, but always as a complement to, not a replacement for, core medical and therapeutic treatment. In a holistic, supportive environment, such as a recovery or wellness setting that aims to care for the whole person, activities that promote relaxation, reduce stress, and support overall wellbeing can be valuable additions to the main treatment. Halotherapy, with its calming, soothing, spa-like quality, may be offered alongside other wellness practices, such as relaxation, mindfulness, gentle exercise, massage, or time in nature, to help people unwind, de-stress, and focus on self-care. For people working on recovery from a substance use or mental health condition, this kind of relaxation and self-care can genuinely support their wellbeing and complement their treatment. However, it is essential to understand that the core of any effective recovery or treatment program lies in evidence-based medical, psychological, and therapeutic care, and that wellness activities like halotherapy are supportive extras that enhance the experience and promote calm, rather than treatments for the underlying condition. So halotherapy can be a pleasant, beneficial part of a holistic wellness or recovery experience, contributing to relaxation and a sense of care, as long as it is understood as a complement to, and never a substitute for, proper treatment. A good program balances effective clinical care with supportive, restorative activities.
