Coincidence? A new study in Lancet Neurology found that astronauts do not get enough sleep and may rely on sleeping pills. Also today, ISS astronaut Reid Wiseman (also the number 1 twitter, vine, and photo user from space) tweeted about his sleeping problems…

I bungee-corded myself to a wall last night attempting to create the “normal bed” feeling. Worked well but the old sleeping bag won at 2am.

The conclusions of the study include that sleep deficiency in astronauts is prevalent in space, and also in the months leading up to spaceflight. The study also concludes that sleeping problems needs to be addressed with countermeasures to promote sleep. A news article about the Lancet Neurology study is here.

The first of its kind study — the most extensive study of sleep during spaceflight ever conducted has found that astronauts suffer considerable sleep deficiency in the weeks leading up to and during spaceflight.

Nasa expects astronauts to catch onto 8.5 hours of sleep per night. However, the study has revealed that crew members in spaceflight on an average get over 2.5 hours less sleep every day.
