Multi-Wearable Approach for Monitoring Diurnal Light Exposure and Body Rhythms in Nightshift Workers.

Aim: As our understanding of light's impact on human health grows, studies examining light exposure and related health outcomes in everyday settings are increasingly important, particularly in high-risk groups like nightshift workers.

Methods: In this observational study, we monitored personal light exposure and physiological functions in a large cohort of healthcare nightshift workers using a spectrally resolved light dosimeter and wearable body temperature, actigraphy, and electrocardiography sensors.

Results: Our findings revealed a common occurrence of unfavorable light conditions during both shift types.

Night work takes on different aspects for nurses, from a regulatory, individual, physiological, collective and organizational point of view. It is important to be able to rely on the resources that make night work bearable by taking these different elements into account. Exploration of the personal, groupal and organizational variability observed in a university hospital and propositions to facilitate the management of night work while preserving the interest of the tasks and physiological rhythms.
