Shivering and exercise convert white fat to brown
National Institutes of Health (NIH). The study authors said their findings may lead to ways to activate brown fat so as to fight obesity and diabetes. The investigators found that moderate exercise or shivering from being cold increased people’s levels of the hormones “irisin” (produced by muscle) and “FGF21” (produced by brown fat). Rises in irisin levels after 10 to 15 minutes of shivering were about the same as after an hour of moderate exercise on a stationary bicycle. Laboratory tests showed that irisin and FGF21 turned human white fat cells into brown fat cells over six days, according to the study published Feb.

We are all born with supplies of brown fat around our necks, natures way of helping to keep us warm as infants. Until only a few years ago, it was thought to vanish in early infancy, but we now know that brown fat is present in most, if not all, adults. Adults with more brown fat are slimmer than those without. Excitement in the brown fat field has risen significantly over last few years because its energy-burning nature makes it a potential therapeutic target against obesity and diabetes, said Dr Lee. White fat transformation into brown fat could protect animals against diabetes, obesity and fatty liver.

Exercise has healthy benefits when it comes to sleep
If they cant get that much exercise, I tell them to do what they can, and 15 minutes p90X3 results is OK, said Dr. Philip B. Fuller, a physician at Mary Washington Healthcares Sleep Medicine Specialists, in Fredericksburg, Va. And exercise seems to be one of the only things thats been shown to reliably increase deep sleep, which has important benefits for memory and energy recovery. Vigorous exercisers are almost twice as likely as non-exercisers to report having a good nights sleep every night or almost every night during the week. They also are the least likely to report sleep problems.
