Can sleeping in a hot room under covers cause a fever? The bedroom is hot, we have a fan on but doesn’t make it cool. And I slept under 2 covers all night. I woke up and felt like my body was warm so I checked my temperature and it said 101.5, I now have gotten out of the covers trying to cool off and it now says 100.7.

Edit: so if you can’t have a temperature change from this then why is my temp increased?
