I always sleep nude and haven’t worn a stitch in many, many years. If it’s mid-winter and super cold, I just add another blanket, and if my shoulders still get chilly peeking out I might wear a soft cozy shirt. Never anything down below, though! Too uncomfortable! Even in the occasional times when I’m visiting/traveling and sometimes sleeping in a room or household with family/friends who aren’t that nude-friendly, I always slip off what I’m wearing under the covers until morning. No one has ever complained. Just do it. It’s the best way to sleep.
It really is, and once you try it and get used to it, it is really really difficult to go back to wearing anything, even loose shorts, to sleep again.
I mostly sleep naked but now I am getting old I worry that if I die in my sleep the lady that lives upstairs that has a key to my place will see me in the nude, I guess I won't be worrying about, that sadly I won't see the shock and horror on her face because I'll be dead.
I sleep naked since I was 16, so that's for 52 years now. Fortunately my wife does too. It's just the most comfortable way to sleep. (And also to be awake )
I have slept naked for at least the last 40-45 years. There is absolutely no way possible that I could get a good nights sleep otherwise!
