I've noticed the swelling of my hands when hiking as well. My
understanding, which a nurse or physician can correct or elaborate on,
is that the body is mostly water, and the lymph system is responsible
for transporting water where it is needed. In normal living homeostasis
is maintained and we don't notice we are mostly water. When we
exercise, the constant use of leg muscles develops hydrostatic pressure
that moves water from legs to other extremities, the hands for hikers.
The pressures in the lymph system are relatively small so that you can
make the swelling go down by walking with arms upraised, eyes cast
upwards in rhapsodic bliss as the heavenly body swings to its own rhythm
down the trail... Or stop, take a nap, and let the body once again
achieve calm, centered homeostasis...
