How Sleep Affects Pain, Injury Recovery, and Athletic Performance

Whether you’re recovering from an injury, dealing with persistent pain, or trying to perform at a higher level, the quality and quantity of your sleep can influence how your body responds to training and rehabilitation.

Sleep Can Change How You Experience Pain

Pain isn’t determined solely by what is happening in a muscle, joint, tendon, or disc. Your nervous system also plays an important role in how strongly you experience pain.

Research has shown that sleep deprivation can increase pain sensitivity. A systematic review and meta-analysis found that sleep deprivation can reduce pain thresholds and tolerance while increasing spontaneous pain and pain sensitization in healthy individuals.¹

This doesn’t mean your pain is “just because you’re tired.” Instead, sleep is one of several factors that can influence how sensitive your nervous system is and how well your body tolerates physical stress.

For someone already dealing with an injury, consistently poor sleep may make an already-irritable area feel even more sensitive.

Sleep Matters for Recovery and Performance

Training and rehabilitation provide a stimulus. Recovery is when your body has the opportunity to adapt to that stimulus.

Sleep plays an important role in physical and cognitive function, and athletes may be particularly affected when they consistently fail to get enough sleep.

A systematic review of competitive athletes found that sports involving speed, tactical decision-making, and technical skill appeared particularly sensitive to changes in sleep duration.²

More recent research examining sleep interventions in athletes has also found that increasing sleep duration – either through nighttime sleep extension or napping – can improve certain physical and cognitive performance measures.³

In other words, your exercise program matters, but so does your ability to recover from it.

How Much Sleep Do You Need?

For most healthy adults, at least 7 hours of sleep per night on a regular basis is recommended, although individual sleep needs vary.⁴ Many adults – and especially busy athletes, parents, and professionals – may benefit from more.

Consistency matters too.

If you’re training hard, recovering from an injury, and regularly sleeping five or six hours per night, improving your sleep may be one of the simplest ways to better support your overall recovery.

Some practical strategies include:

• Maintain a relatively consistent sleep and wake time.
• Give yourself enough time in bed to actually obtain the sleep you need.
• Keep your bedroom cool, dark, and quiet.
• Limit caffeine later in the day if it interferes with your sleep.
• Reduce activities immediately before bed that consistently delay your sleep.
• Consider short naps when nighttime sleep is insufficient and your schedule allows.

There isn’t one perfect sleep routine for everyone. The goal is to find habits that allow you to consistently obtain enough high-quality sleep.

Don’t Ignore Recovery When Treating an Injury

Physical therapy isn’t simply about finding the right stretch or exercise.

Training load, strength, sleep, nutrition, stress, movement, and recovery can all influence your ability to tolerate activity.

That’s why two people with similar injuries may recover differently – and why simply treating the painful area isn’t always enough.

At Zeek PT & Recovery in North Austin, we take a comprehensive approach to rehabilitation. Our goal is to identify what’s limiting your movement or performance, progressively rebuild your capacity, and prepare your body for the activities you actually want to return to.

Because successful rehabilitation isn’t just about getting out of pain.

It’s about getting back to doing what you love.

Recover. Rebuild. Perform.
