Katie Wintters teaches pilates and works out at least three times a day. Needless to say, she's in very good shape, but she says working out and eating right haven't been the only keys to her great health.

"I actually lost 20 pounds over a three month period," she explains.

She attributes much of her well-being and weight loss to a cedar box. It's an infrared sauna. Unlike normal saunas, it uses infrared rays to heat your body.

"The tissues get hot so it makes the heart starts pumping faster, so you get a workout while you're in there because your heart rate goes up," Katie explains.

She's been using it for more than a year, and says she's in better health today than ever before.

”It's eliminated toxins (from the body). I haven't been sick in a year and a half, and the energy is amazing," she says. Katie says she's sold on the sauna because she's seen and felt the difference thirty minutes in the sauna can make.

"Even though I teach pilates three times a day, I've been very sluggish, but after I get out of the sauna, I am full of energy," she says.
