Dry salt therapy, also known as halotherapy, has gained popularity for its purported health benefits, particularly concerning the integumentary system, which includes the skin, hair, nails, and associated glands.

This article delves into the mechanisms through which dry salt therapy aids the integumentary system, backed by clinical trials and case studies.

Understanding Dry Salt Therapy

Dry salt therapy involves the use of pure sodium chloride (salt) in an environment that replicates the natural salt caves found in Eastern Europe, known as the salt cave spa. This environment is typically created in a controlled room where fine salt particles are dispersed into the air in specific concentrations, allowing them to be inhaled or settle on the skin.

Mechanisms of Action

Anti-inflammatory Effects: Salt has natural anti-inflammatory properties. When inhaled or applied topically, it can help reduce inflammation, which is beneficial for various skin conditions such as eczema, psoriasis, and acne.

Antibacterial Properties: Salt is known for its antibacterial effects. It can help to kill bacteria on the skin, reducing the occurrence of infections and promoting healing.

Skin Barrier Enhancement: Salt can aid in strengthening the skin’s barrier function, helping to retain moisture and protect against environmental pollutants.

Exfoliation: The fine salt particles act as a natural exfoliant, removing dead skin cells and promoting cell regeneration.

Clinical Trials and Research

1. Efficacy of Halotherapy in Chronic Dermatological Diseases:

Study: A randomized controlled trial conducted by Chervinskaya AV and Zilber NA (1995) on the effects of halotherapy in patients with chronic dermatological conditions.
Findings: Patients with eczema and psoriasis showed significant improvement in skin condition, reduced itching, and decreased lesion size after regular halotherapy sessions.

2. Halotherapy for Atopic Dermatitis:

Study: Research published in the Journal of Dermatological Treatment (2018) by Kuryk et al.
Findings: The study demonstrated that children with atopic dermatitis who underwent halotherapy experienced a marked reduction in disease severity, improved quality of life, and decreased need for topical corticosteroids.

3. Psoriasis and Halotherapy:

Study: A clinical trial by Nemeş RM et al. (2017) published in the Romanian Journal of Morphology and Embryology.
Findings: The trial reported significant improvement in psoriasis symptoms, with patients showing a reduction in the Psoriasis Area and Severity Index (PASI) scores after a series of halotherapy sessions.

Case Study: Psoriasis Management:

Patient: A 45-year-old male with a 10-year history of severe psoriasis.
Intervention: The patient underwent 20 sessions of halotherapy over a period of 10 weeks.
Outcome: Post-treatment, the patient reported a 70% reduction in the severity of lesions, improved skin texture, and decreased itching. The improvements were sustained with periodic maintenance sessions.

Case Study: Eczema in Pediatric Patient:

Patient: A 7-year-old girl with chronic eczema.
Intervention: The child participated in halotherapy sessions twice a week for 8 weeks.
Outcome: Significant improvement in skin hydration, reduced redness, and itching were observed. The child’s reliance on topical steroids decreased, and there was a notable enhancement in overall skin health.


Dry salt therapy offers a promising complementary treatment for various conditions affecting the integumentary system. Its anti-inflammatory, antibacterial, and exfoliating properties contribute to its effectiveness in managing skin conditions like eczema, psoriasis, and atopic dermatitis. While further research is needed to establish standardized treatment protocols, existing clinical trials and case studies provide a strong foundation supporting the therapeutic benefits of halotherapy.

Individuals considering halotherapy should consult healthcare professionals to determine its suitability for their specific conditions and to ensure a comprehensive approach to skin health.
