16 Reasons Why Sleep Should Matter to Healthcare Providers


Written by Andrew Koppejan, PT

Sleep impacts so many different aspects of our health and life. I want to highlight 16 reasons why this topic of sleep should matter for us as healthcare providers.


Are you ready?

Here we go!


#1: Sleep Affects A Lot of People

Disrupted sleep affects a large portion of the population. When looking at the stats, sleep problems are common. In the USA, there are an estimated 50-70 million adults suffering from a sleep or wakefulness disorder(Colten & Altevogt, 2006). And about 1/3 of the adult population is affected by insomnia on an occasional basis, while between 9-12% experience insomnia on a more chronic basis (Morin et al, 1999).

When looking at the Canadian data, survey studies show that 20% of Canadians are dissatisfied with their sleep. More importantly, 40% reported having at least one symptom of insomnia. (Morin et al, 2011).

#2: Disrupted Sleep Affects Our Older Adult Populations

With the aging baby boomer population, our patient caseloads will likely see an increase in older adults. Disrupted sleep is more common within this demographic. Research has shown that nearly 30% of all older adults (>65) have problems with staying asleep. (Bliwise, 2016).

#3: Sleep Impacts Sport Performance

Disrupted sleep affects sport and motor performance. There was an interesting study that was published in the Journal of Paediatric Orthopaedics in 2014 (Mileski et al, 2014) evaluating the impact of sleep on injury prevalence in adolescents. Although it was a small data sample of 112 adolescent athletes, they found that the amount of sleep per night was associated with injury risk. Athletes who slept less than 8 hours per night had a 1.7 times greater risk of being injured than those who slept more than 8 hours. They say:


“Sleep deprivation can affect motor function, mood, and cognitive functions, all of which could affect a young student’s athlete’s performance and injury risk.”


#4: Chronic Insomnia Contributes to General Health Problems

Chronic insomnia, the most common sleep disorder, affects our general health in a number of areas. In a cross-sectional, retrospective study, researchers discovered that those with insomnia reported more medical problems than those without insomnia. In fact, the adjusted odds ratio (adjusting for depression, anxiety and other sleep disorder symptoms) of having any chronic medical problem was 5.17 times higher in those with insomnia than those without insomnia (Lichstein et al, 2016).

#5: Many Patients with Chronic Pain Have Sleep Problems

Poor sleep isn't just related to episodes of acute pain. A strong majority of those with chronic pain have sleep problems. Studies have shown that 50-70% of those with persistent pain have poor sleep quality. (Haythornthwaite et al, 1991). The research is still evolving in this area, but researchers are beginning to understand that disrupted sleep and chronic pain share similar neurobiological pathways.

#6: Sleep Deprivation Impacts Motor Performance

Motor performance matters in what we do as physiotherapists. Sleep deprivation studies (Fullagar et al, 2014) highlight the impact on performance:

36 hours of sleep deprivation shows faster exhaustion (11% decrease) during treadmill walking test

Sleeping less than seven hours per night has been shown to decrease performance testing in alertness, reaction time, memory and decision making.

#7: Acute & Chronic Pain Contribute to Poor Sleep

Whether acute or chronic in nature, pain contributes to poor sleep. Research shows that sleep becomes more fragmented with increased awakenings throughout the night. As well, REM and deep sleep are decreased throughout the night.

#8: Sleep Contributes to Increased Depression & Anxiety

Sleep and depression / anxiety are coupled together closely. Those with insomnia are 10x more likely to have depression and 17x more likely to experience anxiety when compared to normal sleepers (Lichstein et al, 2016).

#9: Poor Sleep is a Driver for Chronic Pain

Although it's not apparent on the surface, research has been showing that poor sleep is a driver for chronic pain. In a 2008 study of the general population, research highlighted the relationship between sleep duration and following-day pain. The study showed that getting less than six hours (or more than nine hours) of sleep was associated with substantial increases in pain frequency the following day (Edwards et al, 2008). As well, research has shown that poor sleep can lead to increased attention to pain during the day which can predict night-time sleep disturbance (Smith et al, 2004).

#10: There's a strong association between sleep & headaches

The relationship between sleep and headaches continues to evolve. Those with tension headaches were 3X more likely to have severe sleep disturbance. And this number increases substantially for those with migraines and chronic headaches (Odegard et al, 2010).

#11: Poor Sleep Predicts Fibromyalgia Pain

It's no surprise that those with fibromyalgia experience sleep troubles. It is one of the clinical symptoms associated with this syndrome. Studies have shown that 94-96% of those with FMS are poor sleepers. Although it's worthwhile to note that self-reporting within this demographic is often worse than objectively measured sleep deficits (Martinez et al, 2014). Research is beginning to show that sleep predicted pain in this patient population and sleep quality was predictive of long term pain (Bigatti et al, 2008).

#12: Poor Sleep is a Hallmark Symptom of Concussion Patients

Sleep disturbance is a hallmark sign of a concussion syndrome. Neurocognitive screening is increasingly used to help with the management of concussions and return-to-play and physiotherapists are becoming more involved in concussion management. Interestingly, sleep can impact the results of neurocognitive screening of patients. Research has shown that athletes getting less than 7 hours of sleep the night before testing will have lower scores and higher total symptoms on baseline testing. As well, subjective sleep quality is correlated to a greater number of symptomatic complaints with baseline testing (Kutscher, 2016).

#13: Sleep Affects Memory and Learning

It’s still an area of active research, but so far it appears that sleep does play a definite role in memory and learning. Whether it’s deep sleep or REM sleep, each sleep stage plays a role in memory formation and consolidation. Slow wave or deep sleep appears to support long term memory consolidation while REM sleep helps to consolidate procedural memories and emotional memories.

#14: Sleep Supports our Immunity

Whether you’re working with patients in an acute care setting or a community setting, having patients with strong immunity is a foundational pillar in healthy living. Experimental evidence has begun to confirm our understanding that sleep deprivation increases our susceptibility to illness while sleep helps our recovery from illness (Peever et al, 2007).

#15: Poor Sleep Puts People at Risk of Accidents

Sleep has been shown to have significant effects on our ability to perform tasks. Whether driving a car, operating machinery, etc, our patients need to be safe in performing their daily activities. Research has shown that skipping a night of sleep has the same impact as being legally drunk. There are hundreds of thousands of accidents each year that are a result of excessive sleepiness.

#16: Obstructive Sleep Apnea is a Silent Killer

Obstructive sleep apnea is a commonly under-diagnosed sleep disorder that can be putting our patients’ lives in danger. Those with obstructive sleep apnea have a 20 year shorter life expectancy and they have a higher incidence of hypertension, coronary artery disease, strokes, GERD, heart failure, and heart attacks (Chung et al, 2008).

Ok, I'm Convinced...

As you can see, sleep’s effects are far reaching for our patients. Sleep is something that we take for granted. Unfortunately for our patients with sleep problems, it can be a lonely journey that impacts their health, their relationships, their mood and their pain.

As mentioned, I’ve spent the past 18 months diving into this topic. I’d love for you to join me on this journey about sleep.

  • Caro says:

    As a now retired physiotherapist with insomnia for over 32 years i have many of the problems stated including fibromyalgia. I have always blamed my fibro on lack of sleep.

    • admin says:

      Hi Caro. Thanks for your comment! I’m sorry to hear that you’ve struggled with insomnia for so long. Definitely those with fibro have a high prevalence of disturbed sleep. Research is beginning to uncover that disturbed sleep precedes pain in those with fibromyalgia, which is quite an interesting finding.
