NASA scientists describe seven factors that help astronauts sleep soundly in space.

Next time you complain about jet lag, consider the average astronaut aboard the International Space Station.

If you consider a trans-atlantic flight disruptive to your sleep schedule, think how you’d feel if you experienced up to 16 sunrises per day….

It’s no surprise then that the experts at NASA are not just a bunch of rocket scientists, they’re also pioneers in understanding many areas of human biology, including the physiology of sleep.

So how does NASA ensure their astronauts are able to function at peak performance in the most challenging environments?

The NASA blog lays out 7 ways that astronauts address sleep and circadian rhythm disruptions. These are:

  1. Schedule Sleep and Wake Times
  2. Sleep Education and Training
  3. Sleep Environment
  4. Light
  5. Non-prescription Sleep and Alertness Substances
  6. Sleep Cognitive Behavioral Therapy
  7. Pharmacologic Interventions

From the NASA ‘Mission Pages’ blog:

Circadian misalignment and sleep deficiency occur during both short- and long-duration spaceflight, and can lead to significant, fatigue-induced errors and long-term sleep loss. In addition to spaceflight, employees working in Mission Control, where shift work and abnormal hours are common, often experience the effects of circadian misalignment.

Chronic sleep deprivation and circadian desynchronization are associated with health complications such as metabolic disorders, cardiovascular diseases, gastrointestinal diseases and some types of cancers. NASA’s flight surgeons and scientists have devised tools for crew members and Mission Control employees to help promote a more natural circadian rhythm in space and during shift work back on Earth.
