Sleep and physical recovery

Whether you are recovering from a workout, an injury or simply the physical demands of daily life, sleep is doing more work than you might realise.

What it is

Sleep is one of the primary times the body repairs and rebuilds itself. During deeper stages of sleep, the body releases hormones that support muscle repair, tissue growth and immune function. This matters not just for athletes, but for anyone recovering from illness, injury, or simply the physical wear of a demanding job or lifestyle. Poor or insufficient sleep can slow healing, increase the risk of further injury, and leave you feeling physically depleted even when you are technically resting.

Signs to notice

• Persistent muscle soreness or fatigue that does not ease with rest
• Slower healing from minor injuries, cuts or strains
• Getting sick more often than usual
• Waking up feeling physically unrested despite enough hours in bed
• Reduced physical performance or coordination
• Relying on caffeine or willpower to push through physical tiredness

What helps

• Aim for consistent sleep and wake times, since regularity supports the deeper stages of sleep where repair happens.
• Prioritise sleep especially during periods of intense physical activity, illness or injury recovery.
• Keep your bedroom cool, dark and quiet to support uninterrupted, deeper sleep.
• Avoid intense exercise, caffeine or heavy meals too close to bedtime, as these can disrupt sleep quality.
• Build a simple wind-down routine to signal to your body that it is time to shift into rest.
• Notice how your body performs and recovers on well-rested days versus poorly rested ones, which can strengthen motivation to protect sleep.
• If pain is disrupting sleep, speak to your healthcare provider about adjusting treatment timing or positioning.
• Treat rest days and sleep as part of your training or recovery plan, not as optional extras.

When to reach out for help

If sleep problems are persistent, if you are not recovering physically despite adequate rest, or if pain or another health issue is disrupting your sleep, speak to your doctor. A professional can assess whether an underlying issue is affecting your sleep and recovery.
