This is highly anecdotic and I&#x27;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&#x27;d end up sleeping <i>less</i> and going to bed <i>later</i>. I&#x27;d generally end up sleeping for about 6-7 hours, from 01:00 or so -- and feeling a lot better in the process.
