:cold: Ever get a chill after a dive, even after 80 degree F water in 90 F air? I'm certainly a stout bodied fellow, but I do and I've seen skinny gals just shivering and shaking!! Two reasons:
(1) 80 F is not 98.6, so the body core temp is going to be lowered :frosty: more so with a diver fully submerged than a swimmer who keeps his head party above water.*
(2) With the boat moving, and air moving across wet hair, the water evaporates even faster, causing a cooling effect on this sensitive area.*
:grad: * For reasons I won't go into here, I'll simply state that when a person is chilled, up to 40% of heat loss can be through an uncovered head, making head cover as important as a jacket in cool weather - and a very good idea after any dive. Many urban men wore hats until the 1960s, when J.F.Kennedy and the Beetles made styled hair more popular, but you'll notice that outdoors men still do, hot or cold. (In hot weather, it's to protect this sensitive area from sun exposure.)
Any solid fabric, duckbilled "gimme" cap will work, the kind :fork: farmers here call a "winter cap," not the lighter weight meshback cap that farmers call a "summer cap" and urbanites call a "trucker cap," but - I think black caps work the best.
So, if you get chilled after dives, or just don't want to be, stick a black, solid fabric, duckbilled "gimme" cap in a dry pocket of your boarding bag, and wear it after every dive.
And of course, wear at least a neoprene beanie while diving. I know, hardly any do, but it helps a lot too.
