Hi Brian, 

Interesting concept of a study.  I always wondered how astronauts sleep when up in space. Good to know this might also provide insight into sleep on Earth too. When I picture sleep in space, I always think of sci-fi: astronauts on trips that last for decades, frozen in their pods. Suspended animation I guess. But that’s probably a different kind of sleep for a different article. 


This is a very interesting study which still has to be done, if I got that right? I have tried a sleep tracker once, that I plugged into my ears and it was keeping up with my sleep during the night. It was a small device that was attached to a small computer and my smartphone. But I couldn’t really handle it, because the earplugs themselves hurt my ears. I hope the astronauts will tell us more about sleep in those conditions. Fantastic science!


There is nothing worse than sleep deprivation, something that I was acutely suffering from after the birth of my second son. It is interesting to see that space travel affects your sleep pattern in such a major way, something that I was not aware of. I assumed that astronauts would have a dark room to sleep in, so to read that their circadian rhythm is adversely affected, is new to me.

It would be interesting to see the results of the the Sleep in Orbit study that is being done by the European Space Agency. I am sure it will be beneficial for the future of space travel.
