Hypothermia
Hypothermia is defined as subnormal body temperature - a lowering of the body core temperature. Unconsciousness can occur when the body core temperature drops from normal (98.6 F) to approximately 86 F. Sudden immersion in cold water cools your skin and outer tissues very quickly. Within 10 or 15 minutes your core body temperature begins to drop, your arms and legs become numb and completely useless. You may lose consciousness and drown before your core temperature drops low enough to cause death.

What To Do If You Suspect Hypothermia-- Move the victim to warm shelter. Check breathing and heartbeat. You should check very closely for as long as two minutes. Start CPR if necessary. Remove victims clothing. Lay victim in a level face up position with a blanket or other insulation beneath them. Wrap victim in warm blankets, sleeping bag or other warm covering. If medical attention is not near or is delayed, apply heating pads or hot water bottles to the head, neck, chest and groin. Do Not Apply heat to arms or legs or give them a hot bath. This forces blood out through the cold extremities and back to the heart, lungs, and brain which will further drop the core temperature. Apply warmth by direct body to body contact. Never give alcoholic beverages but if they are alert enough you can give them hot drinks.
