I’m not quite sure what’s going on here. This week I’ve had moments when I lay down and suddenly am cold. My room is the same temperature as the rest of the house, warmer if the sun is coming in. I put on multiple layers and take forever to warm up enough to sleep. Today I walked around all day feeling fine. I laid down for a nap and was cold. Managed to fall asleep and woke up freezing. The room was 75 degrees at this point and I have 3 layers on (I’ve never needed 3 layers and I often wake up sweating because hubby curls up to me since I’m warm). I laid there for awhile and finally got up to eat. I put on a sweater and curl under a blanket while I ate. I barely ate anything and was mostly thirsty. An hour later I finally pull my hands out to see if hubby thinks they are cold (he did). I’m not sure if it’s a hormone thing or what. I’m not cold all the time, just about the time I go for a nap. Sorry for the long post but any ideas on what’s going on?
