Lack of sleep and diabetes

Poor sleep quality was associated with a significantly higher prevalence of diabetes (OR 1.76, 95% CI 1.14 to 2.71), independent of possible confounders. A sleep duration of ≤6 h increased the risk of diabetes (OR 1.25, 95% CI 1.03 to 1.51, p<0.01) compared with the group that slept 6–8 h,” according to a study published by BMJ Open.

Lack of Sleep and Diabetes

Relation of Sleep Quality and Duration to Type 2 Diabetes
Medical researchers and analysts indicate that insufficient sleep can increase blood sugar levels, making it more challenging to manage diabetes effectively.

The prevalence of type 2 diabetes has been steadily rising, affecting approximately 92.4 million people in China alone. Aging, gender, obesity, and an unhealthy lifestyle are well-known risk factors, but emerging research shows that sleep quality and duration also play a crucial role.

A prospective study involving 6,599 initially healthy, non-diabetic men, with a mean age of 44.5 years, suggested that sleep disturbances were linked to an increased prevalence of diabetes after a 14.8-year follow-up. 

The Sleep Heart Health Study, which included 1,486 subjects, found that sleep durations of less than 6 hours or more than 9 hours were associated with an increased risk of diabetes and glucose intolerance, compared to 7–8 hours of sleep per night.

Experiments and Results

Experimental studies have demonstrated that sleep deprivation and disturbed sleep can decrease glucose tolerance and compromise insulin sensitivity. This suggests that habitual short sleep duration may lead to insulin resistance by increasing sympathetic nervous system activity, raising evening cortisol levels, and decreasing cerebral glucose utilization. 

The increased burden on the pancreas due to insulin resistance can eventually impair beta-cell function, potentially leading to type 2 diabetes.

The BMJ further evaluated the distribution of sleep quality and duration across the population, examining how it varied by the incidence of diabetes. Multiple logistic regression analysis was employed to assess associations between sleep difficulties, subjective sleep duration, and diabetes risk, adjusting for various confounders such as age, sex, education, smoking, alcohol consumption, BMI, and physical activity.

While these studies spanned populations from China, Europe, the USA, and Japan, they may not fully represent global populations, particularly those in the Indian subcontinent or Africa, where type 2 diabetes is also highly prevalent. The results' applicability to different ethnicities and cultures is still under investigation.

In Conclusion

Fellow readers, it is essential to prioritize sufficient sleep as it is vital for your body's overall functioning. Studies have confirmed that poor sleep quality and short sleep duration are linked to a higher prevalence of diabetes, regardless of factors like age, obesity, family history, alcohol consumption, smoking, physical activity, and other health conditions.
