12 Diabetes Prevention Tips Backed by Medical Experts

9. Prioritize consistent, quality sleep

Poor sleep and irregular sleep patterns are linked with higher diabetes risk in many studies. Short sleep duration, fragmented sleep, and disorders like sleep apnea affect hormone balance, appetite regulation, and how the body handles glucose. Aim for a consistent sleep schedule with seven to nine hours per night for most adults, and keep a calming pre-sleep routine that avoids heavy meals, caffeine late in the day, and screens an hour before bed. Create a sleep-friendly environment: cool, dark, and quiet. If you snore loudly or wake gasping, discuss sleep apnea with your doctor because treating it can improve blood sugar control. For shift workers, try to stabilize sleep timing as much as possible and use naps strategically. Better sleep supports energy, decision-making, and appetite control, making other prevention efforts easier to sustain.
