Actually it's pretty in-line with it. Natural circadian rhythm is ~25hrs, with some individual variance, and it's easier to extend a circadian rhythm than shorten it. Jet lag research finds that flying west (lengthening), you can adapt at a rate of ~1hr per day. It's not crazy to think that someone might naturally be at 26-27hrs, then stretch it an hour each day no problem. |
