Cold thermogenesis is the practice of intentionally exposing parts of the body to specific levels of cold stress. Years of research now shows this can cause significant increases in metabolism and calorie burning, can increase insulin sensitivity and help control blood glucose levels, reduce systemic inflammation, help with sleep and recovery, and potentially fight certain types of cancer as well as promote overall longevity.
How can cold thermogenesis do all this?
Think about it this way: human beings are probably not meant to be in environments constantly at 70 degrees Fahrenheit, our average modern temperature in which we live, work, play and exercise. Constant temperature control is a modern, technological contrivance. Whether it was an asteroid that blocked out the sun and wiped out the dinosaurs, to reports of a flood that left the planet underwater, our ancestors at some point experienced a dark, cold world, some form of an ice age, and a very likely necessity to evolve and even thrive in cold temperatures. Some researchers have even correlated the increase and control of indoor heating to the rise in obesity (and yes, you must keep in mind, correlations should be taken with a grain of salt)
The point here is that we’re arguably not meant to be at a constant, comfortable temperature, and that true, optimal health requires at least occasional cold thermogenesis practices.
