# What is a simple glossary for salt therapy words?

## Answer

A few words get used loosely. Here they are without fog.

**Halotherapy** — breathing dry, fine salt particles dispersed by a halogenerator in a purpose-built room. **Speleotherapy** — time in a *natural* underground salt mine or cave. **Thalassotherapy** — seawater and sea air, historically at coastal spas. **Halogenerator** — the machine that grinds pharmaceutical-grade salt into a dry aerosol. **Micron** — a millionth of a meter; halo particles are often discussed as 1–5 microns. **Hygroscopic** — salt draws moisture. **Active room** — generator on, measured aerosol. **Passive room** — salt décor, little or no generator aerosol. **Negative ions** — talked about a lot; research on mood is still catching up to folklore.

If a host cannot tell you whether their room is active or passive, ask again. If you want a house Angelina will introduce, share your city and Ask the owner.
