I may be way off base here but hang with me...
Would you recover quicker if you were cold 100% of the time or warm? I understand the body works to stay at 98.6 but if you are cold then your muscles are contracting to keep you body warm- this uses up not only calories (energy) but also your muscles have little-no down time as they are constantly contracting. So if you work to stay at a temperature that your body finds agreeable (relaxed, warm, noneed for contractions for warmth, and no extra work to use calories) you can recover quicker. Does that sound legitimate?
