I remember camping when I was younger in the Boy Scouts, and coming home after a weekend trip and always being tired. I always thought that it was due to all of the energy I spent regulating my body temperature in the elements.
Years later, in the military, we would spend 3-14 days in the wilderness for training. I was in much better shape, and would not get tired from simply being outside.
This may be anecdotal, but it seems to lend support to the author's claims.
