Consequences of Circadian Disruption in Shift Workers on Chrononutrition and their Psychosocial Well-Being

Int J Environ Res Public Health. 2020 Mar 19;17(6):2043. doi: 10.3390/ijerph17062043.


The workers and employees in various institutions are subjected to different shifts and work schedules. The employees work not only at daytime but also during odd hours at night. The biological clock of an individual is often altered during night shifts. This affects the psychosocial well-being and circadian nutritional intake of the worker. Disturbance in circadian rhythm results in the development of metabolic disorders such as hypertension, dyslipidemia, dysglycemia, and abdominal obesity. In the present review, we discuss the nature of shift work, sleep/wake cycle of an individual, chrononutrition, dietary habits, and meal changes with regard to timing and frequency, related to shift work. We also discuss the relationship between nutritional intake and psychosocial well-being among shift workers. The review may be beneficial for prevention of metabolic disorders and maintaining sound psychological condition in shift workers.

Keywords: biological clock; circadian rhythm; diet; psychosocial; shift; workers.
