Hot yoga studios operate at 105°F with no medical screening or regulation

Hot yoga (Bikram-style) classes are conducted in rooms heated to 95-108°F (35-42°C) with 40-60% humidity, yet there are no regulatory requirements for medical screening, temperature monitoring, or emergency protocols. Participants routinely experience core body temperatures exceeding 103°F during class, which the American College of Sports Medicine considers dangerous. Documented risks include rhabdomyolysis (muscle breakdown that can cause kidney failure), heat stroke, cardiac arrhythmias, and acute myocardial infarction in those with underlying conditions. Despite these risks, studios typically post only a waiver and a suggestion to 'stay hydrated' -- there are no mandatory temperature limits, no required cool-down zones, no defibrillators, and no trained medical personnel. This persists because hot yoga is classified as a fitness activity, not a medical procedure, placing it outside any health department jurisdiction. Studio owners have a financial incentive to maintain extreme heat because it is the core differentiator of the product, and acknowledging medical risk would undermine marketing claims that the heat 'detoxifies' the body -- a claim with no scientific support.
