HOT ?

I paddle canoes n kayaks. We take cold showers to ease cold water shock when going in.

Over time, the hot idea should increase capillary function under your skin...more AC.

I live in Florida near the main artery to retirement villages. Early season Sept/Oct brings the wail of EMS dragging victims out to the cooler.
