Lighting based on light-emitting diodes (LEDs) not only is more energy efficient than
traditional lighting, but also enables improved performance and control. The colour, intensity …

Abstract Objective Fatigue Risk Management Systems (FRMS) are a data-driven set of
management practices for identifying and managing fatigue-related safety risks. This …

As human space exploration advances to establish a permanent presence beyond the Low
Earth Orbit (LEO) with NASA's Artemis mission, researchers are striving to understand and …

The success of interplanetary human spaceflight will depend on many factors, including the
behavioral activity levels, sleep, and circadian timing of crews exposed to prolonged …

Sleep deficiency and the use of sleep-promoting medication are prevalent during
spaceflight. Operations frequently dictate work during the biological night and sleep during …

The basic goal of this research is to determine the best combination of light wavelengths for
use as a lighting countermeasure for circadian and sleep disruption during space …

Sufficient sleep duration and good sleep quality are crucial to ensure normal physical and
mental health, cognition and work performance for the common people, as well as …

Journey to Mars will be a large milestone for all humankind. Throughout history, we have
learned lessons about the health dangers associated with exploratory voyages to expand …

Spaceflight exposes crewmembers to circadian misalignment and sleep loss, which impair
cognition and increase the risk of errors and accidents. We compared the effects of an …

The circadian clock and sleep are essential for human physiology and behavior;
deregulation of circadian rhythms impairs health and performance. Circadian clocks and …
