It also slows cooling, if only by changing the surface area to volume ratio.

I use to kid some of the guys diving saturation that it would take them an extra day or two to decompress because they were overweight. There are not too many skinny saturation divers and it never seems to slow them down. A few extra pounds seems to be welcome when breathing helium for long periods of time...
