This sort of effect is common for folks who work with their hands in very 
cold water:  fish filleters, for example.  Studies show (can no longer 
recall the sources) that you can acclimate your hands to immersion in 35-40 
F water, over a period of many weeks, working up from a few minutes to a 
full eight hour work shift.  OTOH, if you fail to maintain the regime, you 
lose the acclimatization pretty fast:  couple weeks or so, IIRC.

Acclimatizing your body to full immersion must involve something more 
demanding, although when I swam regularly in the ocean, as a kid, we could 
stay out in 63-64 F water for at least an hour, moving actively.  The 
demarcation was quite sharp, however:  at 60 F, we could not stand it for 
more than 15 minutes; at 70 F, we were in heaven, and could last basically 
all day.  Again, we were swimming actively.
