Hot or cold

So I normally run pretty warm, get hot easily and stay that way/have a hard time cooling down. And I mean this has pretty much been my whole life (currently 26yo), never changes not even around any parts of my cycle, until recently...I've now had like 2 or 3 days within this past week where when I'd normally be warm or worse, instead I was comfortable or on the colder side. Not really worried, honestly enjoying it in those moments/days, but just curious if anyone else experiences something like that or has an idea if its related to something?
