Rough Sleeper/Cold Room

M

I posted this a few days ago in a different group and nobody ever responded. If you're a rough sleeper, will that negatively impact your ability to temp properly? For example, if I start waking around 5am and roll around a bit, dozing, when I temp at 6am, will it still be accurate?

Also, I woke 30 mins early this morning because I was freezing and my temp was about 5 tenths higher than usual. I covered and dozed for a bit and re-temped when I wasn't cold. It was more along the normal temps. Should I have taken the first one even though I was cold?
