Sleep, Fatigue, and Mood during Mission V of the Hawaii Space Exploration Analog and Simulation (HI-SEAS)

Sleep is vital for maintaining human performance, especially for tasks that involve vigilance.  The study will assess sleep and activity patterns and overall mood of crewmembers during Mission V of the HI-SEAS project. The specific objectives of this study are to: a) assess sleep/activity, fatigue, and changes in mood while living in the habitat, and b) assess the effect of ambient light and resupply activities on sleep, fatigue, and mood.

Crew members will receive medical-grade actigraphy devices to wear throughout the study. Activity logs and questionnaires will evaluate sleep quality, daytime sleepiness, insomnia symptoms, and mood states. Ambient light and temperature in the common area and sleeping spaces will be monitored using data loggers.
