A dose of the cold could help weight loss and reduce heart disease

"Scientists have found that exposure to the cold can cause a little known type of fat tissue, called brown adipose tissue, to clear harmful fat molecules from the blood stream. Cold causes the brown fat to burn off these high-calorie molecules, turning them into heat to keep the body warm. Excessive levels of these high-calorie fat molecules, or triglyceride-rich lipoproteins as they are known, from food can cause the arteries to harden and lead to cardiovascular disease. They also cause the build up of unhealthy white fat deposits around the body, which leads to obesity. Researchers at the University Medical Centre Hamburg-Eppendorf, who conducted the research, found that keeping mice at temperatures of around 39.2F (4C) increased the ability of the animal's brown fat to burn off these molecules and reduced levels of body fat"
