Lately, I’ve been waking up in the middle of the night drenched in sweat, and I think my mattress might be the causing it. It’s a memory foam one I’ve had for a couple years, and I never had this issue until the weather started warming up. I’m using lightweight sheets and even a fan, but it’s still super hot. I’m not ready to replace the whole thing yet since I don’t have any budget. Any tips to cool it down? Appreciate any help!!
