Staying warm between dives

[mcdiver]

Assuming that you are diving wet, there is a constant flow of new water throughout the suit, though usually minimal if sized correctly. Your body has to reheat this "fresh" water all the time.

When you exit the water, you are basically wearing nothing but a "wet sponge" and when the wind blows off the lake, it dramatically cools the body because you are wrapped in this "wet sponge." Get out of the suit between dives. If you are that cold, it really doesn't pay to go back into the water immediately after changing tanks, you are asking for nothing but trouble.

I have seen some divers pour warm water into the wetsuit between dives, I think this gives the diver a false sense of warmth/security, sure it felt good, but the bottom line is that you are still wearing this wet wetsuit and the wind and cool temperatures are your enemy.
