Lack of sleep can significantly affect blood sugar levels and increase the risk of metabolic diseases. Researchers from the Chinese Laboratory of Life Sciences and Biomedicine reached this conclusion after analyzing data from over a thousand individuals. The study, published in Medical Xpress, demonstrates that sleep patterns are directly linked to glucose fluctuations and metabolic stability.
Participants in the experiment recorded their sleep habits over several years, and then wore continuous blood glucose monitoring devices for two weeks. Based on their sleep duration, the participants were divided into four groups, ranging from severe sleep deprivation (4–4.5 hours) to normal sleep patterns (8 hours). They were also categorized based on their bedtime habits—those who went to sleep early and those who consistently stayed up late.
The analysis revealed that individuals suffering from chronic sleep deprivation experienced significant glucose fluctuations, with their average variation being 2.87% higher compared to those who had sufficient sleep. Those who habitually stayed up late had an increased fluctuation of 1.18%. The most extreme deviations were observed in participants who combined short sleep duration with late bedtimes—their glucose levels changed most erratically, indicating a high risk of metabolic disorders.
Researchers emphasize that unstable blood sugar levels are a major risk factor for diabetes and cardiovascular diseases. The findings suggest that consistent and adequate sleep may be a crucial component in preventing metabolic disorders. Maintaining an optimal sleep duration and going to bed earlier can help stabilize glucose levels and reduce the risk of serious health conditions.
