Thanks for all the replies, I see that I am not alone with this symptom. Honestly I had not thought it was related to position but the ones that cause me to sweat are pretty much all overnight, thus the confusion with hormones being off for over a year. So a new consideration for me, thanks. I am still working on adjusting hormones just in case. I also feel flushed and cold at the same time sometimes. I just recorded my overnight sleep breathing and found that the time of night I start in with the hot flushes, my breathing is significantly more intense, not the shallow breathing of my early sleep hours, so maybe something is reving up that gets my breathing elevated and overheats me. My heart rate from my pulse oximeter changes around a bit during the night, but dosent go even to 90 but a few times ususally. No way to know my overnight blood pressure with the equipment I have. The daytime flushing is exacerbated by heat, warm shower, rubbing my face with a wash cloth, putting on olive oil (my moisturizer), sunlight, sometimes a clothing seam can do it. A cool breeze is uncomfortable on my face also.These are things I never had before. I am not looking forward to summer!
