Short sleep duration (≤5 hours per night) and difficulties maintaining sleep are associated with a significantly increased incidence of type 2 diabetes in middle-aged men.

If you are a middle-aged man, prioritizing sleep is a critical diabetes prevention strategy, not just a wellness luxury. Specifically, aim for more than 5 hours of sleep and focus on sleep continuity (staying asleep). If you struggle with waking up frequently during the night, this is a specific metabolic risk factor that warrants attention, potentially through sleep hygiene or medical evaluation for sleep apnea, as it independently raises your diabetes risk.

GoodSupportsHIGH confidence
Men reporting new diabetes at follow-up more often reported short sleep duration (≤5 h per night) (16.0 vs. 5.9%, P < 0.01)... and difficulties maintaining sleep (28.0 vs. 6.3%, P < 0.001) at baseline than men who did not develop diabetes.

Why this rating

Prospective longitudinal study with 12-year follow-up and adjustment for major confounders (age, BMI, depression, snoring), though reliant on self-reported sleep data.
