Is it possible for a human being to stay in a deep freeze for an extended period?
When you are in a deep freeze, your body keeps shivering out of cold temperature. Shivering keeps you warm, boosting your body's heat production tenfold, it uses a lot of energy, so can be exhausting. When shivering stops, it's time to worry. Even if you are fat, you will begin to lose heat quickly, falling into a state of hypothermia once your core body temperature drops below 35C. As the body cools further, breathing becomes laboured and it becomes hard to think straight. Ultimately, the heart muscles begin to seize up, and because blood is then pumped around the body so inefficiently, tissues and organs fail through lack of oxygen. So it is not possible for a human being to stay in a deep freeze for longer period
