Sleep affects strength, recovery, appetite, and mood. Skimp on it and your numbers in the gym drop, injury risk goes up, and it’s harder to stick to your nutrition plan.
Aim for 7–9 hours most nights. Consistency matters as much as total time: similar bed and wake times (including weekends) help your body adapt. Wind down with dim lights and no screens for 30–60 minutes before bed, and avoid big meals or caffeine late in the day.
If you have diabetes, poor sleep can worsen blood sugar control, so prioritising rest is part of managing your condition. Track sleep for a week—even roughly—and see how it lines up with how you feel and how your training goes.
Small tweaks (earlier dinner, no phone in bed, a cool dark room) often make a bigger difference than any supplement.
