I ask you the same thing I asked Rayiner above: try it for yourself.
Take a letter size piece of paper and put it on the floor. Strip naked. Have a "cold shower", then stand on that piece of paper for just two hours.
Bonus points if you manage to stay standing with a wet cloth bag on your head. Extra points if you manage this after having been on reduced calories and no sleep for 48 hours.
In your case nothing happens if you step off the paper.
I don't know that you should really suggest this. I've had hypothermia, it is quite unpleasant. And you don't know the state of his health, a myriad of bad things could happen.
