護理人員的工作壓力偏高，常焦慮和失眠，且常因為過勞而產生疼痛、身體不適，有一個替代療法—低能量雷射光療（又稱為光生物調節療法），可以幫助醫護人員盡快恢復體力，減少病痛及對藥物的依賴。作者本人投入低能量雷射光療研究超過二十年，對於疼痛、誘發特定腦波使人放鬆或改善睡眠問題，皆有深入的研究，臨床試驗證據顯示，不只護理人員，一般大眾皆可使用低能量雷射光療來改善上述的症狀或疾病。

The high pressure nature of their work makes nursing staffs relatively susceptible to high levels of anxiety and insomnia and to poor mental health. Low level laser therapy (photobiomodulation therapy, PBMT) is an alternative approach to reducing pain and inducing specific brainwaves that has been shown to improve anxiety, insomnia, and poor mental health. The author, who has studied PBMT for over 20 years, provides research evidence that PBMT may be effectively applied on medical professionals as well as on the general public.
