Handling Fatigue

There is no single accepted definition of the different types of fatigue a person can experience, but MF (cognitive impairment), physical fatigue and sleepiness are frequently cited in several studies [1]. In this study we are going to consider sleepiness as a consequence of fatigue, either mental or physical. Fatigue can be originated from mainly two different sources. It can be sleep (or lack of sleep) related or task related. Sleep play an essential role in fatigue mitigation and physiological recovery and inadequate sleep cycles can lead to or worsen fatigue scenarios. When considering task related fatigue, it can arise from passiveness (boring tasks) or activeness (high workload). A person in more likely to fall asleep when the task at hand is dull or boring or not requiring a lot of interaction. In the other hand, in a hectic environment a person is less prone to fall sleep, but the high workload can lead to fatigue build up.
