George Brainard is a neuroscientist working with the National Space Biomedical Research Institute. He's testing how light affects astronauts working and sleeping in space.

George Brainard: [---1---] Now when they're on the space station, they're circling the planet every 90 minutes. [---2---]

Your circadian rhythm is what tells you when it's time to sleep and wake up. [---3---]

George Brainard: That's the opportunity that we're working on. Can you blue-enrich white-appearing light and get a stronger circadian stimulus for the astronauts, and will this in fact help their sleep?

An astronaut here on Earth experiences a 24 hour light-dark cycle, day-night cycle just like you and I. So they've gone from a 24 hour day to a 90 minute day. It's tied to light, in particular, the blue-indigo region of the spectrum, according to Brainard. Dr. Brainard is also testing to see if a pure form of blue light will boost the waking performance of astronauts. So for example, if an astronaut is waken up out of sleep and there has to be a spacewalk for emergency purposes, you want that astronaut at their peak alertness. Blue light's earthly applications might include combating the effects of jet lag and shift work.
