Well, I shouldn't type when I am sleepy :)
Dipping may compound this effect by simple CO2
accumulation-derived vasodilation. That is when
dipping under...so there might be a synergistic
between the two actvities.
When one dips under water, one holds breath.
Holding breath increases blood's CO2 content.
Body responds with vasodilation to take more blood/O2
throughout the body.
Cold water may initially result in vasodilation
to heat the body.
Then vasoconstriction to preserve body heat, and
maintain core temp.
With increased blood flow, decreased circulation
to body's appendages, and increased CO2 levels
the vasculature is taking a workout. This perhaps
restores homeostasis to the afflicted blood vessel
in the brain. :)
So...if it works, great!!! gotta try it myself...
It would give me a change of routine from the
bizillion push-ups and sit-ups, and the ensuing
endorphin high...now that always works...
