To clarify things a little more now that I think about it. I didn't notice the big reaction to the change in temperature today that I noticed yesterday. Hence why I was asking about the 'bigger' temperature change causing a bigger reaction.
Actually, today I did go all the way and checked the thermometer and then came back up slow to see at what depth I was seeing the temperature drop. If I wouldn't have already been getting chilled quite nicely I would have taken a couple more dives down but I knew to play it safe and headed back for shore after the first dive.
Also, this will sound a lot strange and crazy to ask this question. Do you guys normally do nothing more than relax/breathe up in between dives when you know you are dealing with the colder water below or do you spend more time on the surface finning/swimming around to help keep the body temperature warmer. I have always been going from diving to breathing up and as a result I have no body movement/body heat generation taking place between dives. It's only the 64/17 degree surface temperature and about the same, maybe a little warmer, air temperature that allowed me to have a nice 40-45 minute session this morning.
