There's a new public recognition of the link of salt and health, a "saline solution." As described in our blog back in January, salt-lined "caves" are the latest "in thing" in this week's Time Magazine's Living section. Reporter Jennine Lee-St. John seems to be on a mission to convince Time's readers that the halotherapy in Chicago's Galos Caves replicates the longstanding success of treating Eastern Europeans suffering respiratory ailments with recuperative sessions in salt mines. But it's stress relief that attracts US Midwesterners, not relief from air pollution. Lee-St. John describes the attraction as a "quest for holistic relaxation."
