Wearable technology keeps pace in the space race: The International Space Station (ISS) is monitoring the earth and reporting back on climate change, and how crystals and crops can grow in space.
Astronauts and scientists on-board the ISS need to be fit and alert, and sleep is important. Sleep patterns, however, can be disrupted due to time zone changes – there can be 16 sunrises in one day – and work shift patterns.
