does baking heat set off flares?

My eczema came back a few months ago after being basically clear since high school, which caught me off guard. I’ve been trying to figure out what’s setting it off. It seems worse on nights I bake bread (most weekends now), but I can’t tell if it’s the oven heat and kitchen humidity, or just that baking pushes my bedtime to 1am instead of my usual 11. Last weekend I was up until 1:30am proofing dough, and by morning my forearms were red and itchy again. Is it the heat, or is it the lost sleep catching up with me? Anyone dealt with something like this?
