Scientists think that adopting a bear's cave closure during the winter months will allow humans to travel great distances to the solar system so they wake up fresh and rejuvenate at their destination. Hibernation will become an important aspect of deep space travel. A single astronaut consumes 30kg-66lb-Food and water, more than 16 months round trip filling a giant spaceship to Mars. But hibernating astronauts don't eat or drink a lot, or they need a lot of oxygen.

Cooling the body to reduce a body's demand for energy and oxygen can also cause a torpor-like state. This is an excerpt. Read the full article here
