Nurses function in a high-stress environment characterized by substantial physical, mental, and emotional demands, resulting in perceived fatigue levels significantly higher than those of workers in other professions []. Given that stress and fatigue contribute to various health issues among nurses and recognizing the correlation between nurses' health and patient outcomes, identifying effective methods for alleviating stress and fatigue is imperative []. Nurses working in hospitals care for patients with serious illnesses every day and interact directly with the families of patients at the end of life, which exposes them to various stressors []. Additionally, advances in medical technology have increased the number of tools that nurses must manage, and difficulties in communicating with healthcare professionals in different departments add to the everyday stress they experience []. Long-term exposure to these stressors can lead to physical health problems, such as stomach ulcers, heart disease, and high blood pressure, as well as mental health issues like depression, insomnia, and anxiety. This highlights the need for effective strategies to manage stress and promote overall well-being []. Shift nurses, in particular, experience irregular sleep patterns and sleep loss due to the nature of their work, which can result in sleep deprivation []. Additionally, high-intensity and continuous stress can activate the sympathetic nervous system, leading to poor sleep quality []. In response to sustained stress, the body manifests various physical symptoms such as headaches, insomnia, fatigue, gastrointestinal discomfort, and musculoskeletal pain as well as physiological responses such as increased heart rate, elevated blood pressure, and muscle tension through the autonomic nervous system and the hypothalamic-pituitary-adrenal axis []. When the homeostatic balance of the body is disrupted by heightened stress, reduced sleep quality, and fatigue, the overall quality of life (QoL) diminishes []. The QoL of the nurses in their job as healthcare providers is highly related to both nurses’ own comfort as well as patient comfort []. Shift work leads to irregular life patterns that can negatively affect nurses’ satisfaction with life and lower their QoL, which can also decrease their interest in patients and have negative effects on overall patient care [,]. Nurses with a high QoL are better capable of providing high-quality nursing services in response to patients’ requirements, which in turn enhances their satisfaction and further increases the productivity and efficiency of nursing care [,]. Accordingly, when nurses’ QoL is high, their happiness and satisfaction with life increase, leading to positive outcomes, such as job satisfaction, high-quality nursing care, and reduced turnover intentions; as such, QoL management is important [,].
