The Hot New Thing in Saunas: Infrared

Proponents say you can get a better sweat at a lower temperature.

How are they different from a traditional sauna?
Proponents say the lower temperatures of infrared saunas let you stay in them longer to reap greater benefits—from weight loss to increased circulation to “cellular detox.” “There are two components to detoxing: One is supporting your detox pathways, so that your body is able to flush out the toxins”—everything from environmental pollutants such as cadmium and arsenic to alcohol and sugar—“and the other is repairing the damage done by the toxins,” says Dr. Amy Myers, author of the New York Times best-seller The Autoimmune Solution. “Traditional saunas cause your body to sweat out toxins. Infrared saunas not only flush out toxins more effectively, they also help your cells and tissues regenerate and support your immune system, which is why I recommend them to my patients.” 
Why are these a thing now?
The technology behind infrared saunas isn’t new, but the buzz around them has been growing since 2009, when Dr. Mehmet Oz went on The Oprah Winfrey Show and extolled their benefits. (No, audience members didn’t receive free infrared saunas.) Since then, gyms, spas, and wellness centers across the country have been installing the rooms. Gwyneth Paltrow endorsed them in her lifestyle publication, Goop, and power couple Jennifer Aniston and Justin Theroux installed one in their home gym.
Does this really work?
A 2012 study in the Journal of Environmental and Public Health found traces of lead, arsenic, cadmium, and mercury in participants’ sweat and concluded that “sweating deserves consideration for toxic element detoxification.” As far as infrared’s particular effectiveness, there’s no scientific evidence. But many people find heat treatments of all types relaxing, and destressing has its own health benefits.
