Overview

• Study followed over 5,000 participants for nearly seven years, finding a 46% higher risk of diabetes among night owls.
• Increased risk persists even after accounting for unhealthy lifestyle factors such as poor diet and lack of exercise.
• Higher body mass index and larger waist circumference observed in late chronotypes contribute to greater diabetes risk.
• Night owls also have significantly more visceral fat and liver fat, which are linked to metabolic disturbances.
• Researchers suggest adjusting meal times and sleep schedules to potentially mitigate diabetes risk.
