How to Self-Rescue If You Fall Through Thin Ice

In this video, Kenton Whitman explains how to survive a fall through ice on a frozen lake or river.

The explanation could have been tighter and more engaging, but it gets really interesting around the 6:40 mark when Whitman ventures out onto some ice and falls through it to demonstrate the self-rescue technique (and he’s not wearing a wetsuit). Watching him relax to mitigate the cold shock response in realtime is spellbinding. His calmness really drives home that if you don’t panic and think clearly, you actually have a lot of time and energy to get yourself out of trouble. From the Four Phases of Cold Water Immersion:

While it varies with water temperature and body mass, it can take 30 minutes or more for most adults to become even mildly hypothermic in ice water. Knowing this is vitally important in a survival situation, since people would be far less likely to panic if they knew that hypothermia would not occur quickly and that they have some time to make good decisions and actions to save themselves.

Oh and don’t miss when Whitman gets back into the water so that you can see him climb out from another camera angle. Don’t try this at home, kids.
