Uncle Pug:1. Evaporation of water on the surface of the suit removes heat. Removing your suit and drying off with a towel will keep you from giving up heat to the evaporation.
2. Circulation is somewhat restricted when wearing a wetsuit. Cold water will also cause the blood vessels in the extremities to constrict further reducing blood flow. Getting out of your suit during the SI will allow normal circulation to be restored. This is not only important for keeping warm but is also better for offgassing.
That certainly sounds reasonable, as befits the voice of reason.
Will do on my next dive.
