Stepping into the 5 Star Salt Caves can feel like an out-of-this-world experience: Here you are on South Pearl Street, but the soft pink glow of the place looks like the surface of another planet, complete with a fine, sandy salt floor. The state's first-ever salt cave is packed with the purported healing benefits of — you guessed it — salt, which is said to neutralize the electromagnetic radiation emanating off of our phones and computers and help to clean pollutants out of our respiratory system. The most immediate and gratifying perk of this healing zone is its calm: Each fifty-minute session at the 5 Star Salt Caves feels like it flies by, leaving frazzled patrons refreshed and recharged after a mid-day meditation in the briniest of seclusions.
