I had no idea these things were out there, but evidently three people died in connection to a "Sweat Lodge" ceremony in Sedona, Arizona, in October 2009.
The news this week is that a self-help guru has been arrested in connection with the deaths.
The LA Times reported that people paid thousands of dollars to attend this event, in which they were sleep-deprived, fed little, and then forced to sit in hot saunas for extended periods.
The variety of "alternative" therapies out there never ceases to amaze me. We will keep an eye on the sweat lodge story.
