Just 3 night shifts can increase risk of diabetes, obesity: Study

In our fast-paced world, many industries rely on night shifts to keep operations running smoothly around the clock. However, a recent study conducted by researchers from Washington State University in the US has shed light on the hidden health risks associated with just three consecutive nights of shift work.

Published in the Journal of Proteome Research, the study reveals alarming insights into how night shifts can wreak havoc on our bodies, increasing the risk of diseases such as diabetes, obesity, and other metabolic disorders.

The research delves into the intricate workings of our biological clock, located in the brain, which regulates our body's rhythms in sync with day and night cycles. When this delicate balance is disrupted by night shifts, it sets off a chain reaction that impacts various bodily functions, particularly those related to blood glucose regulation and energy metabolism.

Professor Hans Van Dongen, one of the lead researchers, emphasises the profound consequences of this disruption. He explains that just three consecutive night shifts are sufficient to throw our body's protein rhythms into disarray, leading to long-term health implications.

Using blood samples, the research team identified key proteins associated with the body's immune system and glucose regulation. While some proteins remained unaffected by night shifts, the majority experienced significant alterations in their



rhythms.

Of particular concern was the nearly complete reversal of glucose rhythms observed in night-shift workers. This disruption not only affects blood sugar levels but also impacts processes crucial for insulin production and sensitivity, further escalating the risk of metabolic disorders like diabetes.

The study's findings add to a growing body of evidence highlighting the detrimental effects of shift work on health. Previous research has linked night shifts to increased blood pressure, raising the risk of heart disease and stroke, particularly among those regularly working during nighttime hours.

The implications of these findings are significant, calling for proactive measures to mitigate the health risks associated with shift work. Employers and policymakers must prioritise strategies to support the well-being of night-shift workers, including implementing regular breaks, providing access to healthy food options, and promoting sleep hygiene.

Furthermore, individuals engaged in shift work should prioritise self-care practices, such as maintaining a balanced diet, staying physically active, and seeking adequate rest whenever possible.

Ultimately, while night shifts may be a necessity in certain industries, it's crucial to recognise and address the profound impact they can have on our health. By raising awareness and implementing preventative measures, we can strive towards creating healthier work environments for all.
