The amazing benefits of salt therapy first came to light in the mid-1800s when, Felix Bochkovsky, a health official in Poland made the observation that salt mine workers rarely suffered from any colds, respiratory ailments or lung diseases. Bochkovsky attributes this to the salt aerosol being inhaled on a daily basis. Salisbury Salt Spa caters to clients suffering from asthma, allergies, and other respiratory problems. What's more, this type of therapy also helps to relieve stress and anxiety, which is achieved due to the negative ions produced from the salt rocks. All this is done while resting on a comfy, zero-gravity chair while soft meditation music plays in the background.
