#173 Warm Air Rises

Survival Tip #173

Warm Air Rises

Warm air rises and cold air sinks. This is something to always keep in mind, but will especially come in handy if you need to put together an emergency shelter. If you are trying to stay warm, avoid high spaces, and keep the area as sealed and compact as you can. An easy way to experience this is lay flat in a well insulated sleeping bag, then bend your knees so you have a foot or two of height. You’ll feel cooler because the warm air will build up in the area your knees have lifted.
