The Survival Medicine Hour with Joe Alton, MD, aka Dr. Bones and Amy Alton, ARNP, aka Nurse Amy discusses altitude sickness, winter car survival, falling through the ice or into very cold water and more. Car Survival equipment should include wool blankets, instant hand warmers, flashlights and extra batteries (fresh), small tool with blade, screwdrivers, pliers etc, foldable shovel, sand or rock salt, flares and reflective large triangles, tow chain or tough rope, jumper cables, water and food, a first aid kit (Doom and Bloom makes a grab and go bag), tarp, noisemaker and more.
To increase your chances of survival in cold water you should wear a life jacket whenever you are on a boat. It enables you to stay alive longer by keeping you afloat without burning too much energy. A built-in whistle is a great item to have on the life jacket also. Keep your clothes on while you are still in the water. Button or zip up to retain some body heat. The layer of water between your clothing and your body is slightly warmer and will help insulate you from the cold.
