I keep waking up at 3ish overheating with an elevated heart rate. I'm not sweaty, so it's not night sweats, and it's not dependent on my cycle. It's almost every night. I can throw the covers off, cool off for a couple minutes and then usually get back to sleep, but I'd love to figure out wtf is going on so I can sleep uninterrupted.
Last round of labs at annual (November 2025) were all normal, not sick with covid/flu etc... I sleep in linen sheets, a cotton blanket, and a light comforter in a linen duvet, no clothing. My room is about 60-62 degrees. Same mattress I've had for years (it's a Purple), so no new changes there. The only change I've made is trying to lose a bit of weight and not eating after 7.
What the heck?!
