Are Night Owls at Higher Risk for Diabetes?

Sleep patterns and chronotypes have long been a topic of interest in understanding individual preferences and their impact on health. Chronotype refers to an individual’s natural inclination to sleep and wake up at a certain time, commonly known as being an early bird or a night owl. Recent studies have suggested a potential link between being a night owl and an increased risk of developing type 2 diabetes. Let’s explore the findings and understand the factors that contribute to this association.

The Night Owl Connection to Type 2 Diabetes

A study conducted by researchers at Brigham and Women’s Hospital and Harvard Medical School analyzed the lifestyle behaviors and sleeping habits of over 60,000 middle-aged female nurses. The study found that individuals with a preference for waking up later, or having an evening chronotype, had a 72% higher risk of developing type 2 diabetes compared to those who tended to wake up earlier.

The association between evening chronotype and diabetes risk was further examined after adjusting for various lifestyle factors such as diet, alcohol use, body mass index (BMI), physical activity, smoking status, and sleep duration. The results showed that even after accounting for these factors, individuals with an evening chronotype still had a 19% higher risk of developing type 2 diabetes.

Unhealthy Lifestyle Habits and Diabetes Risk

One of the key findings of the study was the strong connection between being a night owl and engaging in unhealthy lifestyle habits. Evening chronotype individuals were 54% more likely to have unhealthy lifestyle behaviors such as smoking, inadequate sleep duration, higher weight and BMI, lack of physical activity, and poorer-quality diet. These lifestyle factors are known contributors to chronic diseases, including type 2 diabetes.

It is important to note that while evening chronotype was associated with an increased risk of type 2 diabetes, the study also found that unhealthy habits played a significant role in this association. Factors such as high BMI and low physical activity levels were particularly influential in the higher incidence of diabetes among night owls. This suggests that addressing these lifestyle habits could potentially reduce the risk of developing type 2 diabetes, even for individuals with an evening chronotype.

The Role of Circadian Rhythm and Work Schedule

The researchers hypothesized that the mismatch between a person’s circadian rhythm and their physical and social environment could contribute to the increased risk of diabetes among night owls. This mismatch may occur when an individual’s sleep schedule is opposite to their circadian preference. For example, someone with an evening chronotype may be required to work early in the morning, disrupting their natural sleep-wake cycle.

Previous studies have also found a connection between sleep-wake timing and diabetes risk. In one study, female nurses who had worked daytime shifts for more than 10 years but had an evening chronotype had the highest risk of developing type 2 diabetes. Another study suggested that circadian misalignment, such as being a night owl but working early mornings, could disrupt glycemic and lipid metabolism, contributing to an increased risk of diabetes.

Genetic Predisposition and Other Factors

While lifestyle factors play a significant role in the association between evening chronotype and diabetes risk, there may also be genetic predispositions or other factors that have not yet been fully accounted for. The study’s findings indicated that even after adjusting for lifestyle factors, there was still a slight increased risk of diabetes among individuals with an evening chronotype. This suggests that genetic factors or other unknown variables may contribute to both the preference for evening chronotype and the higher risk of diabetes.

Personalized Approaches and Lifestyle Modification

Understanding the potential risks associated with being a night owl and developing type 2 diabetes can empower individuals to make informed choices regarding their lifestyle. Those with an evening chronotype should be aware of the increased risk and take proactive measures to mitigate it. This includes moderating alcohol use, quitting smoking, increasing physical activity, maintaining a healthy BMI, and ensuring adequate sleep duration.

It is worth noting that changing one’s circadian preference from being a night owl to an early riser may be challenging, as chronotype is influenced by both genetics and environmental factors. However, adopting healthier lifestyle habits can still help reduce the risk of developing type 2 diabetes, regardless of an individual’s chronotype.


The association between being a night owl and an increased risk of developing type 2 diabetes highlights the importance of understanding individual sleep patterns and their impact on health. While evening chronotype individuals may have a higher risk of diabetes, lifestyle factors such as unhealthy eating habits, physical inactivity, and tobacco use also play a significant role.

Addressing these lifestyle factors can help reduce the risk of developing type 2 diabetes, even for individuals with an evening chronotype. Future research should focus on exploring personalized approaches to work scheduling and lifestyle modification to effectively reduce the risk of diabetes in individuals with a preference for waking up later.

By prioritizing healthy habits and making informed choices, individuals can take control of their health and reduce their risk of developing type 2 diabetes, regardless of their sleep preferences.
