One way around that (for hardcore cold water divers), is to do your recovery between dives in a high CO2 state (1-2 breaths per minute), then purge like crazy for 20 seconds before going down. I'd consider that a more advanced technique since the fast purging can be dangerous if you don't know yourself well.
I recently have been experimenting with certain foods & supplement combinations that are highly thermogenic, and cause your liver to really generate heat. This can allow a higher 'thermal gradient', meaning colder arms and legs with a core that is still warm.

eric,
interesting post---thanks for the info.
could you be more specific regarding the highly thermogenic food & supplement combinations?
for cold water diving i have been using high quality fats in my diet in the preceding days. my favourite sources at the moment are flax seed (ground), avocados and hemp oil. recently i got ahold of some MCT oil, which i take 2 hours prior to diving (thanks to a previous post of yours). other suggestions would be most excellent.
cheers,
