Latex isn't "temperature sensitive" like memory foam so it won't "melt" with the blanket. All foam sleeps a little warmer though than some other materials (latex less so than memory foam) because you will sink into it more so an electric blanket may end up being warmer than you think it would. I personally would use a less "electric" way to stay warm and cozy using more natural materials (or even artificial materials) that can both cool you down and warm you up as needed as I believe that electric fields so close around us while we're sleeping could cause other effects. This however is a matter of preference and belief.
