This is highly anecdotic and I'd be happy to counteract it with the opposite experience. Whenever I spend enough time in the outdoors (I used to go camping regularly until a few years ago), I'd end up sleeping less and going to bed later. I'd generally end up sleeping for about 6-7 hours, from 01:00 or so -- and feeling a lot better in the process.
