One of the hottest trends in anti-aging is the sauna. Not just any old sauna, though -- infrared saunas.
From Gwyneth Paltrow to Lady Gaga, some in Hollywood swear by them.
It's basically a sauna on steroids -- infrared light penetrates your skin and heats your body.
Anthony Infantino, a chiropractor at Platinum Wellness in Phoenix, said it works for fat-burning, detox, pain management and cardio rehabilitation.
Infantino said it can burn up to 600 calories in just 30 minutes -- but that's the maximum time to spend inside the sauna.
It may sound similar to a tanning bed, but the UV light emitted from tanning beds is on the opposite side of the light spectrum, so there's no UV skin damage associated with the sauna.
