High-profile actors flock to high-temperature studios.

First there was hot yoga. It became a smash hit: the heat encourages flexibility, boosts heart rate and makes for a cleansing, drenching sweat. Now other forms of fitness are cranking up the thermostat. 

At The Sweat Shoppe in North Hollywood, California, instructors including Naomi Priestley (Jason Priestley’s wife) lead classes in rooms heated to around 80 degrees. Trainer Tracy Anderson of the dance-inspired cardio workout Tracy Anderson Method, a favorite of Gwyneth Paltrow, Molly Sims and Jennifer Lopez, warms her New York and Los Angeles studios to 86 degrees. Hot 8 Yoga in Beverly Hills and Santa Monica attracts their clients including Colin Farrell, Kate Hudson, Drew Barrymore and Russell Simmons, with a barre fusion class in temperatures well past 100 degrees.  And at the recently opened  Hot Pilates, which has attracted celebrity fans Dania Ramirez, Paula Patton and Abigail Spencer, the heat is cranked up to 90 to 100 degrees during their 60-minute mat classes. 

If you are planning on heating up your workout, there are some health risks involved.  According to yoga therapy expert Cora Wen, extreme heat puts dangerous stress on the body, and heat stroke can result in death.   She explains that with all the sweaty bodies in hot classes, temperatures can top 100˚ F, at which point it’s nearly impossible to cool down. In order to play it safe she suggests keeping hydrated and if there are any signs of exhaustion, light-headedness, nausea, confusion, or muscle cramping, during a workout to stop immediately.  She also warns that people who have diabetes, heart disease, lung disease or women who are pregnant may have increased risk factors.
