A Brief Overview of Halotherapy and Its Potential Benefits and Risks

Halotherapy is a form of salt therapy that may be beneficial for respiratory conditions. Inhaling salty air is an alternative treatment known as halotherapy. Some assert that it can

  • treat asthma, chronic bronchitis, and allergies.
  •  relieve anxiety and depression;
  •  treat skin conditions like psoriasis, eczema, and acne

In some parts of the world, such as Eastern Europe, salt therapies have a long history of use, but they are less common in the United States.
This article looks at what the research says about the benefits of halotherapy and any possible side effects.

The sections that follow will go through its history and how it might work in greater depth.

The origins of salt therapy

In Eastern Europe, salt caves are prevalent and a popular destination for halotherapy. However, this is less prevalent in America.

In the nineteenth century, a Polish physician observed that salt mine workers had fewer respiratory issues than other miners. A German doctor also found that people who spend time in salt caves have better lung health.

In the 1950s and 1960s, salt rooms gained popularity as a form of therapy. Halotherapy can be traced back to the Middle Ages. However, researchers have only recently begun to examine its potential benefits.

How might it function?

Proponents of halotherapy claim that it can:

  • enhance pulmonary function
  • Get allergens, toxins, and viruses out of your lungs and nasal passages.
  • alleviate inflammation
  • Cleanse the nasal passages and sinuses.
  • alleviate the symptoms of specific skin conditions

Halotherapy and spaleotherapy are dry salt therapies.

Speleotherapy takes place in salt-containing underground caves. However, they are less prevalent in some regions.

To achieve the same effect, halotherapy employs an artificial environment. In halotherapy centers, a dry salt aerosol is used to spread small salt particles all over the room.

The sea salt usually contains a variety of minerals that are essential for human body, such as:

  • Sodium chloride
  • Manganese
  • Calcium
  • Sulphates

Active salt rooms utilise a salt generator to distribute salt throughout the space. Passive salt rooms contain large quantities of salt without a generator to circulate it.

Does this therapy aid in the treatment of any respiratory conditions?

Some individuals believe that salt therapy is beneficial for respiratory disorders such as asthma. However, there is a lack of research in this field.

The following sections will elaborate on the existing research.


A 2014 study on rats suggested that salt therapy may be beneficial for asthma.

Researchers found that the cells in the lungs of rats were healthier when they were in an environment like spaleotherapy.

According to the authors of a major 2001 review, Trusted Source, there is little evidence that spaleotherapy is beneficial for asthma.

Chronic obstructive pulmonary disease (COPD)

According to some reports, halotherapy may be beneficial for chronic obstructive pulmonary disease (COPD).

Nonetheless, a 2014 review found there is no evidence to suggest that halotherapy can alleviate the symptoms of COPD, according to a reliable source. Hyperbaric chambers are in use for oxygen therapy.


In a clinical trial twenty patients with bronchiectasis were studied for two months using a salt spray by Reliable Source. The test revealed no advantages to using salt spray.

Nonetheless, 65 percent of the participants were satisfied with halotherapy and wanted to continue using it. So, the salt spray might not help with the symptoms, but it might help you feel better and more relaxed.

Adenotonsillar syndrome

In a 2013 study, 45 individuals with adenotonsillar syndrome received either 10 halotherapy sessions or a placebo. After the trial, participants who received halotherapy demonstrated some improvement in their symptoms.

Risks and harmful effects

Little research has been conducted on the safety and side effects of halotherapy.

One modest study shows, People with breathing problems who used halotherapy got a cough, but the 2013 clinical trial of people with bronchiectasis showed that there were no negative effects.

Both of these investigations, however, were limited. Consequently, extensive research is required to examine the safety and adverse effects of halotherapy.

Different salt treatments

Wet salt therapy is an alternative method for treating certain health conditions with salt. A few examples of this are:

  • Saltwater solutions
  • nebulizers
  • Salt baths
  • Salt scrubs
  • Gargling remedies
  • exfoliation
  • Flotation Cells

Some individuals use wet salt therapy to treat respiratory ailments such as the common cold. Others can use oxygen room for beauty treatments and to promote healthy skin. The therapy is also relaxing and beneficial for enhancing general health.

The conclusion

Halotherapy may be a soothing spa treatment, but there is limited evidence that it is effective. According to some research, it may be beneficial for respiratory issues and depression. The majority of physicians are still sceptical.

If you’re interested in halotherapy, talk to your doctor, and always choose professional and expert options. Make sure to let them know if you start having new symptoms after using the therapy.
