What do studies on halotherapy say?
Science hasn’t caught up with the halotherapy hype yet. There are few studies on the topic. Some studies on halotherapy have shown promise, but most research is inconclusive or conflicting.
Here’s what some of the research says:
- In a 2007 studyTrusted Source, people with chronic obstructive pulmonary disease (COPD) had fewer symptoms and improved quality of life after halotherapy. Still, the Lung Institute doesn’t recommend it because medical guidelines haven’t been established.
- According to a 2014 review, most studies on halotherapy for COPD are flawed.
- According to a 2013 studyTrusted Source, halotherapy didn’t improve the outcome of lung function tests or quality of life in people with non-cystic fibrosis bronchiectasis. This is a condition that makes it hard to clear mucus from the lungs.
- Halotherapy triggers anti-inflammatory and anti-allergic responses in people with bronchial asthma or chronic bronchitis, according to 2014 researchTrusted Source.
Almost all research on halotherapy for depression or skin conditions is anecdotal. This means it’s based on people’s personal experiences.
