Recent research findings indicate that working at night and sleeping during the day can have detrimental effects on one’s overall health.
While some individuals may choose or be required to work at night for financial reasons, the study revealed that this work schedule, when done three times a week, could significantly increase the risk of developing metabolic disorders such as diabetes, obesity, and other health issues.
Researchers from Washington State University in the United States found that night shifts can disrupt the body’s protein rhythms that are linked to blood glucose regulation, impacting energy metabolism, inflammation, and contributing to chronic metabolic conditions.
Published in the Journal of Proteome Research, the study involved a controlled experiment where volunteers underwent simulated night or day shift schedules for three days. After their final shift, participants stayed awake for 24 hours under controlled conditions to assess their internal biological rhythms without external influences affecting the results.
Blood samples taken at regular intervals were analyzed to identify proteins present in immune system cells in the blood. The researchers discovered that while some protein rhythms were closely linked to the body’s master biological clock, others exhibited significant changes in participants on night shifts compared to those on day shifts.
Specifically focusing on proteins involved in glucose regulation, the researchers noted a notable disruption in glucose rhythms among night-shift workers, affecting processes related to insulin production and sensitivity.
These findings suggest that the body’s regulation of insulin may try to counteract the glucose fluctuations induced by night shifts, which could pose long-term health risks.
Health experts have corroborated these findings, emphasizing that individuals working night shifts face a higher risk of developing diabetes and obesity due to the physiological changes caused by disrupted biological rhythms.
Wakadaily learnt that, Professor Olufemi Fasanmade, a specialist in Medicine and Endocrinology at the University of Lagos College of Medicine, warned against night shift work, citing its adverse impact on diabetes and hypertension risks.
Similarly, Public Health Physician Dr. Tayo Adeoye highlighted that night shift work not only disturbs sleep patterns but also influences lifestyle habits and hormonal balance, all of which can contribute to negative health outcomes.
He explained, “These disruptions can profoundly impact metabolism, insulin sensitivity, and appetite regulation, ultimately increasing susceptibility to diabetes and obesity.
“This study underscores the importance of addressing the social determinants of health. Night shift workers often face additional challenges such as limited access to healthy food options and inadequate support for managing stress.
“To truly tackle the issue of diabetes and obesity among night shift workers, we need comprehensive strategies that address these broader socio-economic factors.”
