Sleep and Recovery: The Rehab You Do With Your Eyes Shut
6 min read

If I could only change one thing about a patient's week, it would often not be their exercises. It would be their sleep. That surprises people, because sleep feels like the absence of rehab rather than part of it. In fact it is the several hours a night in which your body does its repair work, recalibrates your pain system and consolidates the movement you practised during the day. Nothing you do in the gym competes with it.
This matters more as the nights draw in. Every October, as the evenings shorten across Liverpool and Merseyside and the clocks prepare to go back, my diary fills with people whose long-standing niggles have suddenly become louder. Some of that is the weather driving people indoors and off their feet. A good deal of it is sleep quietly falling apart.
Why sleep matters for injury recovery
Three things happen overnight that are directly relevant to anyone rehabilitating an injury.
Tissue repair. Deep sleep is when the body does most of its growth and repair signalling. Muscle, tendon and bone all adapt to the loading you gave them during the day largely while you are unconscious. Train hard and sleep badly and you have done the damage without collecting the adaptation.
Pain sensitivity. This is the big one. Research consistently shows that short or fragmented sleep lowers pain thresholds. In practical terms, the same injury genuinely hurts more after a bad night. It is not in your head, or rather it is, but in the entirely real sense that your nervous system has turned its gain up.
The vicious loop. Pain disrupts sleep and poor sleep amplifies pain. This is one of the strongest predictors of a problem becoming persistent rather than settling, and it is why I ask about sleep in every single first appointment.
The five things worth changing this week
Sleep advice can become an exhausting list of rules. Here are the ones that actually shift the needle for people in pain.
Fix your wake time before your bedtime. A consistent time out of bed, weekends included, anchors your body clock far more effectively than trying to force sleep earlier. It is also the easier one to control.
Get light early. Fifteen minutes outside in the morning, even on a grey Merseyside November day, does more for your sleep drive than most people believe. Overcast daylight is still vastly brighter than indoor lighting.
Move during the day. Regular physical activity improves sleep quality, and this is one of the reasons I push people to stay active while injured rather than resting. Avoid hard training in the two hours before bed if it winds you up.
Sort out the caffeine. It has a long half-life, so an afternoon coffee is still working at midnight. If you are struggling, make 2pm your cut-off for a fortnight and see what happens.
Deal with the racing mind, not just the mattress. If pain-related worry keeps you awake, that is a legitimate treatment target. Understanding what is actually wrong with your back or shoulder is often the thing that lets people stop lying there catastrophising.
Positioning: how to sleep with a specific injury
Most people can find a workable position. It is worth the ten minutes of experimenting.
Lower back. On your side with a pillow between your knees, or on your back with a pillow under your knees. Both reduce the pull on the lower spine. If mornings are your worst time, a mattress that is too soft to support you is worth considering, though I would not rush out and buy one. My guide to back pain covers the morning stiffness pattern in more detail.
Shoulder. Sleep on the unaffected side with the sore arm supported on a pillow across your chest, or on your back with a pillow under the elbow so the arm is not hanging. Frozen shoulder and rotator cuff problems are both notorious night pain producers, and this small change often buys hours. There is more on this in my shoulder injury page.
Outer hip. If lying on that side hurts, sleep on the other side with a firm pillow between the knees so the top leg does not drop across the midline, which compresses the gluteal tendons.
Neck. One pillow that fills the gap between your ear and the mattress. Not three. Not none.
What about painkillers, alcohol and screens?
Short-term use of pain relief to get through a bad patch of nights is reasonable and worth discussing with your GP or pharmacist. Alcohol is the false friend here: it gets you to sleep faster and then fragments the second half of the night, which is the part you needed. Screens matter less than the internet suggests, but what you do on them matters a lot. Twenty minutes of scrolling bad news is a stimulant regardless of the colour temperature of the display.
If you have had less than a good night for a while, resist the urge to compensate with long lie-ins and naps. Spending nine hours in bed to catch six hours of sleep tends to make things worse. Keep the window tight and consistent.
When to see a doctor
Speak to your GP if you have unrelenting night pain that no position eases, especially with unexplained weight loss, fever or a history of cancer. Also see your GP if you snore heavily and wake unrefreshed with daytime sleepiness, which may point to sleep apnoea, or if insomnia has persisted for months, since cognitive behavioural therapy for insomnia is the recommended first-line treatment and it works well.
Making it part of the plan
When I assess someone across Liverpool and Merseyside, sleep goes into the programme alongside the exercises, because treating one without the other is doing half the job. Home visits have an unfair advantage here: I can look at the actual bed, the actual pillows and the actual chair you fall asleep in front of the telly, which is often the real culprit.
If pain is keeping you awake, that is not something to endure until it passes. It is a specific, treatable problem and it usually responds quickly once we identify what is driving it. You can read more about how I work in musculoskeletal physiotherapy.
