  5. 12. An example of this method of heat loss is sleeping on the cold ground when backpacking.
  6. 14. Cold-induced _____ causing increased urinary water loss occurs at temperature above 20 degrees F. due to peripheral vasoconstriction, which increases blood pressure in kidneys promoting more urination.
