In most hospitals, the levels of light and noise remain constant throughout the day and night, even when the body needs darkness and rest during the night. The consistent lighting throughout the day and night can have detrimental effects on the staff working in rotating shifts. They face challenges in maintaining a normal sleep schedule, alertness, cognitive abilities, and mood, which ultimately weakens their focus and attention, The impact of circadian lighting on the staff has been examined in a pilot study involving 26 nurses working in intensive and rehabilitation departments with circadian lighting, as well as a control department with regular lighting. One criterion for inclusion in the study was that the nurses had at least one night shift per week. The staff kept a diary and completed questionnaires regarding their sleep patterns, work, and well-being. The focus of the study’s questionnaire was specifically on staff members with rotating shifts. Nurses who have been exposed to circadian lighting generally experience improved sleep, as they fall asleep more easily and sleep more peacefully. They also find it easier to wake up in the morning and feel more rested after three days in the circadian lighting compared to the control group The circadian lighting generally has a positive impact on the work environment and behavior among the staff. In the department with circadian lighting, they are conscious of maintaining a natural and regular sleep-wake cycle with light and activity during the day and darkness, calmness, and rest at night. The intensive department has shown the most significant positive response to circadian lighting, which can be explained by the previous constant light and activity. In the rehabilitation department, the lights are normally turned off at night Most staff members are highly positive about the nightlight. However, there have been a few who feel tired in the evening because they lack stimulation from the white light. As a result, they have turned on one of the white light settings in another room as needed circadian lighting ensures a balance between the body’s circadian rhythm and the staff’s need for adequate lighting for their work. It is a holistic solution that contributes to the staff’s work environment, well-being, and health.
