New weight loss trend has people exposing themselves to sub-zero temperatures

It's the latest weight loss trend that has people exposing themselves to sub-zero temperatures to gain from this unusual treatment's many benefits. Even Hollywood star Hugh Jackman, who was recently pictured in a sub-arctic tank credits the treatment called cryotherapy for his fabulous physique.

Cryotherapy, which in Greek means 'cold cure', has been around since the 17th century. But, the whole body technique was only developed in Japan in 1978 to treat rheumatoid arthritis, according to the Daily Mail.

Extreme cold, according to previous research, can stimulate the body into burning fat as much as 800 calories in just three minutes, the report states. Apart from encouraging weight loss, is also known to manage pain, make your skin smoother and improves its complexion.

How does it work? The cryotherapy tank dips below freezing temperatures by using cryogenic nitrogen vapor and reach negative 200 degrees Fahrenheit. This stimulates the body's response to the cold that helps reduce swelling and inflammation, the report reveals.

Rex Sharpe, University of Missouri's associate athletic director for sports medicine told the Daily Mail, "When you get into an area of cold, the blood vessels on the skin shut down and the blood returns to the core." He further explains, this helps the blood to get reoxygenated in the core making you feel refreshed and re-energized. The process helps regenerating skin and muscle.
