Fatigue is a subjective feeling of tiredness which is distinct from weakness. Unlike weakness‚ fatigue can be alleviated by periods of rest. Fatigue can have physical or mental causes. Physical fatigue is the transient inability of a muscle to maintain optimal physical performance. Muscle fatigue is mainly caused by the limitations of a nerve’s ability to generate a continued signal and the reduced ability of the muscle fiber to contract. Many muscle properties change during fatigue including the

Compassion fatigue‚ also known as secondary traumatic stress (STS)‚ is a condition of gradual lessening of compassion over time (Sabo‚ 2011). It is common among individuals who work directly with victims of trauma like nurses‚ psychologists‚ physicians‚ cancer-care providers‚ emergency room personnel‚ chaplains‚ and other healthcare professionals. Nurses intend to provide compassionate and empathetic care to patients but become victims of continuous stress while meeting the needs of the clients and

A recent international group of scientists identified fatigue as “the largest identifiable and preventable cause of accidents in transport operations (between 15 and 20% of all accidents)‚ surpassing that of alcohol or drug related incidents in all modes of transportation. Official statistics often underestimate this contribution.” (Rosekind‚ 1993). Fatigue engendered by sleep loss and circadian disruption can degrade all aspects of human capability. Significant reductions in operator performance
