Effects of sleep deprivation in space

Studies, which include laboratory investigations (Category I) and field evaluations (Category II and Category III) of population groups that are analogous to astronauts (e.g., medical and aviation personnel), provide compelling evidence that working long shifts for extended periods of time contributes to sleep deprivation and can cause performance decrements, health problems, and other detrimental consequences, including accidents, that can affect both the worker and others. == Performance errors relative to sleep loss and extended wakefulness == A meta-analysis (Category I) that was conducted by Pilcher and Huffcutt examined data that were drawn from 19 research studies to characterize the effects of sleep deprivation on specific types of human performance.
