Some animals go into hibernation when the temperature is low and food becomes scarce. The physiological process, which occurs naturally in some species, reduces normal metabolism to a low level for days or even weeks.
These periods of low metabolism, called torpor, let the body temperature of the animals to something above the surrounding air temperature, which in turn helps to save energy.
Humans do not tolerate torpor, but scientists are interested in the idea of producing synthetic torpor in certain situations, such as during space flights.
In a press release from the American Physiological Society, published by EurekAlert Matthew Regan of the Veterinary Faculty of the University of Wisconsin said that synthetic torpor could protect the astronauts from the dangers of space
also reduce the Spacecraft and spacecraft requirements and performance, which can reduce the cost of long space flights.
A journey to planet Mars takes six to nine months, and by this time human passengers would need to use valuable resources such as air, water and food.
Regan and other researchers met on October 27 at the American Physiological Society's "Comparativeity and Integration" conference in New Orleans. Synthetic torpor can be induced by the brain as astronauts could use in space missions and what distinguishes it from sleep makes like.
Aside from reducing the costs and resources needed for long space travel, hibernating humans also has health benefits, according to the SpaceWorks president and former NASA engineer John Bradford] After CNET the Atlanta-based company is already working to hibernate people on long interplanetary journeys.
Bradford said that research has shown that the slowdown in the metabolism of muscle atrophy, bone demineralization, and intracranial pressure is experienced by astronauts in the low-gravity environment in space. Some evidence even suggests it can help protect against radiation.
Doug Talk, the SpaceWorks medical team, said that the human body in space is simply not good and it is important to find a way Man is adaptable to the microgravity environment.
"We have a term in medicine that we call 'biological plausibility,' meaning that when you look at what we do, the human body is considered and how it works," said Talk.
"This technology has biological plausibility and could actually be useful to people in outer space."
