All year round, twenty-four hours a day, everything in the world continues in an orderly manner ……. In the meantime, there is no shortage of twenty-four-hour continuous operation of the industry, such as: hospitals, hotels, etc. Twenty-four hours of non-stop work also brings new problems, shift work sleep disorder to many people bring trouble, affecting the normal life and its work. According to U.S. statistics, about 20 percent of workers are engaged in shift work. People from all walks of life are facing an increasing number of sleep problems due to shift work and the inability to adjust their sleep cycles. Most people experience sleep difficulties after working a late shift. How to reduce the impact of shift work on personal life and their work? First of all: for shift work, a clockwise shift system is recommended. That is, a work schedule from day to evening and then to night. Second: For circadian rhythm correction methods, for people working night shifts, there is already evidence that timed bright light and melatonin can improve circadian rhythm adaptation. Continuous exposure to different light intensities (from 1200-10000lx) for 3-6 hours can recalibrate circadian rhythms, generally by stopping light exposure 2 hours before the end of the workday and avoiding light exposure in the morning. Again: sedative-hypnotic drugs can be used, but, are not necessarily an option. Finally: Recognize that family, social and environmental factors are important in successfully managing shift work-related sleep and its wake disorders. Adhering to good sleep habits and putting them into practice is a foundational strategy for a good night’s sleep.
