Sleep Health & Fitness

Sleep is an essential component to your competitive edge!

Regardless of what you would like to achieve in your athletic or sports performance, whether it is maintaining your current fitness level, improving your performance at the gym, or even training for a marathon, all these goals require a good night’s sleep. 

Sleep is the time when your body is recovering, so it makes sense that without an adequate amount of quality sleep, your body will not be able to repair itself properly. 

While quality sleep has many positive effects on athletic performance, a lack of sleep is detrimental to performance. A great number of concerns can arise when athletes do not receive adequate sleep.

Poor sleep not only has a physical effect, but several studies show that our executive functions are impacted by a lack of sleep, which will contribute to a decrease in reactive speed, fast-paced decision making and learning processes.

If you think you may be suffering from sleep deprivation take our quick quiz and check out the common symptoms of sleep apnea.

Check Your Risk Score Symptoms of Sleep Apnea


Male and female tennis players had decreased serve accuracy of up to 53% after sleep deprivation.9


Chronic lack of sleep is associated with increased risk of injury.12



Lack of sleep shows adverse affects in reaction time in athletes.11



Poor sleep quality has been proven to contribute to faster rates of exhaustion.10



Why Sleep Matters

  • Getting good quality sleep results in more production of growth hormone which is very important for athletic recovery.
  • Sleep gives the body time to not only repair, conserve energy and build up the muscles you have worked during a workout.
  • Deep sleep is particularly important in providing energy to the body (physical rest) and brain (psychological rest).
  • Sleep allows your heart to rest2 and cells and tissue to repair and promotes cardiovascular health3.
  • During sleep, your body produces cytokines, preventing or helping you recover from illness.
  • Quality sleep contributes to improved reflexes and accuracy.
  • Sleep helps everyone to retain and consolidate memories when practicing and learning new skills, contributing to improved performance in the future.4
  • Sleep is also essential for cognitive processing, decision making and adapting to new situations.


Does More Sleep Improve Athletic Performance?

A Stanford University study of men’s basketball players who extended their sleep to 10 hours a night found several positive outcomes. The players ran faster in both half-court and full-court sprints. Their shooting improved by at least 9%6 for both free throws and three-point shots. The athletes also reported improved physical and mental well-being.

Male and female swimmers who extended their sleep to 10 hours also saw many performance improvements. Reaction times off diving blocks were faster7, turn times were improved, and kick strokes increased. Times swimming a 15-meter sprint also improved. Additionally, these athletes experienced improved mood and decreased daytime sleepiness and fatigue.

For those running enthusiasts, sleep deprivation can reduce your endurance: you cover approximately 3% less distance on a lack of sleep and not being well rested. 

For those who love resistance/weight training, a lack of sleep can reduce your muscle strength output you need to lift heavy weights.

The Cost of Poor Sleep on Sports Performance

  • Inhibited ability. In a study of male team-sport athletes who were sleep-deprived, average total sprint times decreased.8
  • Decreased accuracy. After sleep deprivation, male and female tennis players had decreased serve accuracy of up to 53% when compared to performance after normal sleep.9
  • Lower levels of endurance. In a study of male runners and volleyball players, both groups of athletes exhausted faster after sleep deprivation.10
  • Decreased reaction time. A lack of sleep adversely affected reaction time in a studied  group of male collegiate athletes.11
  • Difficulty learning and decision making. Executive functions are impacted by a lack of sleep. Choices such as passing the ball or taking it to the net yourself can be more difficult or made too late.
  • Risk of injury. Research of middle and high school athletes revealed that a chronic lack of sleep is associated with increased rate of injury.12
  • Risk of illness and immunosuppression. Poor sleep habits are associated with lower resistance to illness, such as the common cold.13



Australian WNBA legend and Olympian Lauren Jackson teams up with ResMed

Lauren Jackson is perhaps best known for her achievements on the basketball court and for being arguably Australia’s finest ever basketballer. However, behind all her success, was also someone who has long been struggling with getting a good night’s sleep.

By teaming up with ResMed, Lauren wants to end the stigma of sleep issues for others by sharing her lived experiences of poor sleep. Her aim is to talk about them in both an empowering and vulnerable way so that more people can feel comfortable reaching out for help – just as she has.
