I think this is the biggest drawback to the weighted blankets. I have one for my son that he loves, but cannot keep on long enough to help calm him because of the heat. Of course we haven't tried your product in cotton.

There really isn't a ton of research or more proof of effectiveness for sensory issues due to its nature. What works for one child/adult may not work AT ALL for another (may worsen symptoms). Its a very complicated issue for many. So its try this, try that until you figure out what works for your child or loved one. I never thought weight would be a good fit for my child, but I decided to try it based on some research I did. It helps him settle his body down at night. Its not great research or evidence but it works for him and for many others that are sensory seeking. Just offering a little insight.
