Beyond the Salt Walls: What Actually Happens During a Salt Cave Session?

Two kinds of salt, two different roles

The Himalayan salt surfaces are part of the cave environment. The salt supplied to the halogenerator is the material used to create the dry aerosol you encounter during active halotherapy.

Those are separate roles. Our machine does not scrape salt from the walls or turn the room’s decorative salt blocks into airborne particles. The material placed in the equipment is separately sourced pharmaceutical-grade sodium chloride.

NaCl: what those letters actually mean

NaCl is the chemical formula for sodium chloride. Na represents sodium; Cl represents chlorine as part of the chloride ion in this compound. The final character is a lowercase “l”.

Sodium chloride is also the main ingredient in ordinary table salt. The important distinction is the product specification and intended use. Sharing a chemical name does not make every salt product interchangeable in a halogenerator.

What does USP grade mean?

USP stands for United States Pharmacopeia. Its standards describe requirements for the identity, quality and purity of substances, including sodium chloride.

Our halogenerator salt is specified as 99.9% pure sodium chloride. That percentage describes its NaCl content; USP grade identifies the pharmaceutical quality standard. These details tell you more about the material than a description such as “natural salt” alone.

For our visitors, the practical point is straightforward: we use USP-grade pharmaceutical sodium chloride for our halogenerator. We do not fill it with table salt, bath salts or crushed pink salt from the cave.

What the HALO FX halogenerator does

Our equipment is identified on its housing as HALO FX. A halogenerator’s job is to process suitable salt into fine particles and disperse them into the room air. This suspension of dry particles is called a dry salt aerosol.

The HALO FX manual describes separate controls for salt feed and fan speed. Feeding the salt and distributing the resulting particles are different parts of the process. Settings need to be considered alongside the room and the equipment instructions.

A photograph of our machine identifies the model. It does not measure the particle size or concentration during a particular visit. We therefore do not present a current manufacturer’s performance figure as a measurement taken in our cave.

What happens during a salt cave session in Calgary?

A standard Salt Cave appointment at Joy & Vitality Centre is a private, 40-minute time slot. You settle into a reclining chair while the halogenerator supplies the dry salt aerosol. You breathe normally, without needing to follow a special exercise.

The session takes place at normal room temperature. You remain comfortably seated while the HALO FX halogenerator disperses fine particles of our 99.9% pure, USP-grade pharmaceutical sodium chloride into the room air.

The setting gives you time away from the usual demands of the day. You can keep your eyes open or closed. There is no required meditation skill and no particular sensation you need to produce.

A sound bath, Reiki appointment or massage is also a distinct booking. Choose the practitioner-led service if that is the experience you want; a standard cave appointment does not automatically include one.

What can the equipment and salt tell us about results?

The model and salt specification explain how the service is delivered. They do not guarantee an individual health outcome.

Research into halotherapy has limitations. A 2014 review could not recommend it as a COPD treatment on the available evidence. A 2020 literature review discussed possible use alongside conventional care while noting the absence of official guidelines for the approaches examined.

Our sessions are a complementary wellness experience. Continue prescribed care, and ask your healthcare provider about suitability if you have a respiratory condition or concerns about inhaling dry salt. If you feel uncomfortable during a visit, tell the team rather than treating discomfort as a necessary part of the experience.

Three questions worth asking about any salt room

1. What creates the airborne salt? Ask about the halogenerator, rather than relying on the appearance of the walls.
2. What salt goes into the equipment? Ask about its specification and suitability for the device.
3. What appointment am I purchasing? Clarify whether it is time in the room or a session with a practitioner.
