運用光線來促進健康、減少傷害、恢復功能，在以化學性藥物為主軸的西方現代醫療中，是一項新興、沒有累積傷害的物理性策略，也可以作為護理人員的獨立功能，值得深入探討。「光復能」在不同時間點；使用特定波長；不同色溫、照度的光照調整個體的生理時鐘，作為改善情緒、睡眠品質、調控自律神經系統平衡、提升注意力、延緩失智等的利器。在當今不斷發展和變化的健康領域中，光復能的應用正在快速擴展，並為改善個案生活質量、預防疾病和提高整體健康提供了新的機會。本文將闡述光復能的基本概念，探討它如何應用於不同的健康領域，以及它在未來的發展前景。最後也會討論光復能所面臨的挑戰和潛在的解決方案，以確保運用光照提升和恢復生理或是心理的功能。

The use of light to promote health, reduce harm, and restore functionality is a novel, non-accumulative physical strategy that contrasts with the predominantly chemical approaches used in Western medicine. This strategy may serve as an independent function for healthcare professionals and warrants further exploration. Photoreactivation, achieved by adjusting patients' physiological clocks at different times, utilizing specific wavelengths, varying color temperatures, and using illuminance, is a potent tool for improving mood and sleep quality, regulating autonomic nervous system balance, enhancing attention, and delaying cognitive decline. Light therapy is a rapidly expanding field in healthcare that offers new opportunities to enhance quality of life, prevent diseases, and improve overall well-being. This article elucidates the fundamental concepts of photoreactivation, explores its application across diverse health domains, examines its future development prospects, and discusses the challenges faced by photoreactivation and related solutions to ensure the responsible use of light to enhance and restore physiological and psychological functions.
