Fatigue research focuses on understanding and studying the physical and mental effects of fatigue on the human body. This includes investigating the causes of fatigue, such as lack of sleep, stress, and physical exertion, as well as the impact of fatigue on cognitive function, motor skills, and overall well-being. Researchers in this area may explore strategies for managing and preventing fatigue, as well as developing interventions to help individuals cope with fatigue-related issues. Overall, fatigue research aims to improve our understanding of how fatigue affects human performance and health, and to develop effective strategies for mitigating its negative effects.
