You actually hear this question more often than you think you would, with it usually followed closely by the followup question if everyone should get naked and huddle for warmth as an effective warming secondary strategy. When you are camping in cold weather, is it actually warmer to sleep naked than to sleep with your clothes on? The short answer to this is only if the only clothes you have are damp or wet, if not, then probably not. Each person is slightly different and your exact conditions will be different, but unless you are an experienced camper, just go to sleep dressed in dry layers.
If you are anything like me, you will have to pee at least one time in the middle of the night. Trying to put all your clothes back on without leaving the warmth of your sleeping bag makes sleeping naked almost not worth it just for that reason.
One common mistake is placing your dry clothes next to your wet clothes within your backpack. In no time at all, your dry clothes are now your damp clothes.
There are exceptions to everything though. If you are doing high altitude camping with a really good sleeping bag, then you could actually be better off sleeping naked.
