Space sleep study to understand ageing
Tomorrow the first official British astronaut Tim Peake will blast into space for 6 months.
He’ll be doing lots of experiments and tests that aren’t possible on Earth because of the unique conditions on the ISS 400km above Earth. He’ll even be running the London Marathon from space.
But living in microgravity for so long will take a toll on his body; astronauts experience bone and muscle loss, diminished immune systems and increased inflammation, complaints that also are common in the elderly.
To help find out why this happens an experiment at the University of Surrey with the European Space Agency is mimicking the effects of microgravity. Young healthy men will spend two weeks living in the lab ‘normally’ before spending 60 days constantly in beds that are slightly tilted to simulate the microgravity on board the ISS.
By investigating how these conditions disrupt sleep and body clocks, the study will help figure out the genetic processes that contribute to the health problems experienced by both the elderly and astronauts in space.
