Halotherapy is the breathing of salty air. It is an alternative treatment that has been used since medieval times. In Eastern and Central Europe, underground halo salt caves have long been claimed to provide numerous health benefits.
Going into a reputed halo salt spa for therapeutic purposes will treat your common cold and flu, insomnia, dermatological disorders and many more. When you inhale fine particles of salt, they fall on the respiratory lining and pull water into the passage. This leads to thinning of the mucus making it easier for people to breathe and feel better.
There are two types of halotherapy, dry and wet methods. The dry method of halotherapy is free of humidity and uses dry salt microcrystals, whereas wet halotherapy uses a mixture of salt and water in the air. A typical salt room delivers 5 mg of dry salt aerosol (with particles ranging from 0.1 to 5 microns) into the air during a 1-hour session.
The usual halotherapy plan entails 14 1-hour sessions over 2 months with a 48-hour break in between sessions, with an initial course of 4 sessions being recommended to check for a beneficial effect. A brief worsening of symptoms may occur prior to improvement, which has been termed “speleo-reaction.” This may be due to the breaking up of mucus and its subsequent draining increasing cough.
