There is so much variability involved that I don't think a general
rule of thumb could be applied even to a single individual. For
example, take the instance of a high bg bolus + meal bolus in
anticipation of eating when bg's come down -- followed by a shower
while waiting. The things that come to mind immediately would be the
size of recent bolus, temperature and duration of the shower,
previous body state (were you cool, or just finished a workout?),
how high were bg's (were there ketones) and so on ... all of this
would affect the speed at which the insulin would take effect.
With some experimentation and good record keeping one could develop a
guide for themselves for a set of "usual" circumstances, but this
might be tough given the number of variables. Suffice it to say that
if you take a big bolus and hop in the hot tub, you will probably
come down much faster than if you are just sitting around watching
TV. Even just the speed of a lowering bg's can produce the feeling of
a low, even if bg's are still relatively high.
