Summary

Fatigue and sleep loss problem had been encounter by the astronaut due to the limit of sleeping area and the desynchronization of circadian cycle. This will be resulted in the reducing of the astronaut’s performance and even causing in the increasing risk to safety. Hence we develop a sleep shift scheduling tool, which called SleepScheduler. How can the astronauts avoid sleep loss problem by using SleepScheduler. Here are the function provided by the SleepSchedular. First, Nap time alarm alertness. Usually, the best timing for a people to take a nap is around 2 to 3 pm of the circadian time. SleepSchedular had analyze every individual user or astronaut circadian time and will alert them 3
