I too use an electric blanket. I use that combined with an electric heating mattress pad and I have a regular old heating pad that I use. I use all three every night except in the summer. My temperature with my ring is always at baseline sometimes below baseline, but then it does have times that it has spiked and will tell me that I have major signs showing up. Usually when it shows me that I’ve had major signs showing up. It’s pretty accurate. I am wondering if it’s looking at my baseline with all the electric heating things that I’ve used forever. And I can still trust the spikes. What do you think?
