I was also curious about this. Looks like it is slightly exaggerated [1] It is 17 degrees Fahrenheit, and the study mentions 8.3 degrees Celsius. A linked follow up study in 2013 was able to reproduce temperature increases between 1 and 6 degrees Celsius [2] Also, the results suggest that "...the peripheral temperature increases are primarily the result of increased peripheral blood flow due to peripheral muscular action (and proximity of the femoral artery) rather than a result of psychological (caused by meditation) or physiological (caused by breathing or isometric techniques) states." It looks like it is caused by blood vessels opening up (vasodilation) as a response to certain kinds of breathing exercises. If true, it is just an indirect result of the practice, not some form of body control that extends to other use cases.
