Mission statement header
The mission of the Fatigue Countermeasures Laboratory is two-fold:

1) to provide a better understanding of sleep-related issues as they affect human performance and safety;

2) to develop countermeasures to improve safety, performance, and aid in overall mission success.
News header
Researchers from NASA’s Fatigue Countermeasures Laboratory have published a scientific report detailing the potential risks arising from sleepiness and the use of automated (self-driving) vehicles. The report, published in the Scientific Reports journal on September 14, 2021, reveals some surprising and often paradoxical findings about the “safety” of automated driving in a largely sleep-deprived world.

 Fatigue Countermeasures Laboratory Overview Header
The Fatigue Countermeasures Laboratory at NASA Ames Research Center studies the relationship between sleep loss, circadian desynchrony, cognitive function, and alertness. Performance detriments have been shown to occur in response to circadian desynchrony (being out of sync with one's internal clock), acute sleep loss (insufficient sleep over a short period of time), chronic sleep loss (insufficient sleep over a long period of time), and sleep inertia (grogginess following sleep).

Countermeasures for these effects improve safety, performance, and aid in the overall success of a mission's goal. The primary population of interest is aviation pilots and astronauts, however the Fatigue Countermeasures Laboratory lends its expertise to diverse populations.
