alright... a little physiology here... The human body is a wonderful thing ! When your body gets cold, it protects itself by restricting the blood flow into extremities, this is why you feel colder (faster) in your hands and feet since this is where your smallest arteries and veines are located, and this is the body's way to keep you as warm as possible (together with shaking). From above, if you're diving wet, the blood restriction will happen more quickly. Now, you dive dry... your body is kept much warmer than usual and for your brain it means you're feeling better, no need to restrict blood flow in your extremities, which means as well that is will keep flooding blood in your hands and keep them warmer than in your wetsuit dives ! This is why we typicaly tolerate wet gloves better while diving dry than wet !
Nature is really nice
Downside ? yes there is one
Lower temperature means you are most likely to dissolve more nitrogen into extremities than before, because the blood flow is not diminished and the temperature is lower (PV=nRT)... So you have to be more careful then usual in drysuit and cold diving as you tend to stay longer than before ! Nitrogen dissolved, means it is important to do a safety "deco" stop For most of us, we do it even without knowing it as it takes a while to come back into shore, but I think it is important we realize what we are doing in reality !
Does that help you ? Maybe... I dive, but I know what I'm doing, or at least I try to know as much as I can... Do I know everything ??? No ! I still have plenty to learn !! good thing
