Sleep, Stress and Recovery: The Training You Do Off the Floor
You don't get fitter during your workout. You get fitter while you recover from it. Here's how to recover well.
Key takeaways
- Adults generally need 7–9 hours of sleep for good health and recovery.
- Poor sleep increases hunger and cravings and slows progress.
- Rest days, light movement and stress management are part of training.
Training is a stress on your body. It's a good stress, but only if you recover from it. Sleep, rest days and managing everyday stress are where your body actually adapts and gets stronger.
Why sleep matters so much
During deep sleep, your body repairs tissue and restores energy. When you sleep badly, the hormones that control hunger shift, making you hungrier and more likely to crave sugary, high-energy foods. Poor sleep also makes workouts feel harder.
Most adults need 7–9 hours a night. If you regularly get less, improving your sleep could do more for your results than any new programme.
Better sleep: practical steps
- Keep a consistent bedtime and wake time, even at weekends.
- Put screens away 30–60 minutes before bed.
- Keep your room dark, cool and quiet; a fan helps in hot weather.
- Avoid caffeine in the late afternoon and evening.
- Don't eat a very heavy meal right before bed.
- Get some daylight in the morning.
Stress and your body
Work pressure, traffic, money and family all add stress. Chronic stress can affect sleep, appetite and energy. Exercise itself is one of the best stress relievers, but you also need ways to switch off.
- Take a short walk after work before doing anything else.
- Try slow breathing: in for 4 seconds, out for 6, for a few minutes.
- Spend time with people who lift you up.
- Write down what's on your mind before bed.
Rest days aren't lazy days
Taking one or two rest days a week lets your muscles and joints recover. Light activity on those days, such as walking or stretching, helps you feel better without adding much fatigue. Our 10 daily moves include stretches that work well on rest days.
