**Fresno, CA -** A new study published in Medical Xpress has linked going to bed late with an increased risk of developing type 2 diabetes (T2D). Researchers at an unnamed institution analyzed data from over 5,000 individuals with a mean age of 56 years and a BMI of 30 kg/m2. The participants were divided into three groups: early, late, and intermediate chronotypes, based on their sleep patterns.

The study, which followed participants for an average of 6.6 years, revealed that late chronotypes had a 46% higher risk of developing T2D compared to those with intermediate sleep patterns. The increased risk was not explained by lifestyle factors alone, suggesting that other mechanisms, like circadian rhythm disruption, may be at play.

Dr. van der Velde, lead researcher on the study, explained that late chronotypes, whose body clocks are out of sync with societal schedules, may experience circadian misalignment, leading to metabolic disturbances and ultimately T2D. The study also noted that late chronotypes tend to have higher levels of body fat, including visceral and liver fat, which can contribute to the development of T2D.

**Debate and Criticism**

The study’s findings have generated both interest and criticism. Some commenters on the original article have questioned the validity of the study, arguing that the participants were already predisposed to T2D due to their high BMI and age. They also expressed concerns about potential biases in the study’s design and data analysis.

Others, however, emphasize the importance of further research into the connection between sleep patterns and T2D. The study highlights the potential impact of circadian rhythm disruption on metabolic health, suggesting a potential new avenue for preventative measures.

**Further Research Needed**

Despite the debate, the study’s findings underscore the importance of maintaining healthy sleep habits for overall health. More research is needed to confirm the causal relationship between late chronotypes and T2D, and to identify potential strategies for mitigating the risks associated with disrupted circadian rhythms.
