Thinking about a latex mattress

I currently have a sensaform Sirius mattress. I really like the feel of this mattress but I'm now starting to have hot sweats at night. Would a latex mattress or other type of foam mattress be cooler? I weight just over 10 stone and I'm 5ft 2. My bed base is slatted pine but I have had ply board fitted over the slats. Many thanks
