Optimizing Performance: The Role of Sleep for Athletes

Athletic individuals must train regularly, eat healthy, and rest properly to recover and perform their best. Is sleep different for athletes?

Athletes and Sleep

Physical activity is an important component of a healthy lifestyle. Regular exercise increases longevity and can also reduce the risk of anxiety and depression and improve sleep (Centers for Disease Control and Prevention, 2024). When one area is lacking for athletes, overall performance can suffer. Evidence shows that more or extended sleep can benefit athletes and their recovery and performance. (Bird, Stephen P. 2013) Recommendations for athletes range between seven and nine hours nightly, and elite athletes are encouraged to get at least nine hours of sleep nightly and to treat sleep as much as athletic training and diet.

Sleep is essential for overall health and well-being for both athletes and non-athletes. Everyone needs sleep to feel restored and function their best daily. (Richard J. Schwab, 2024) Other physical benefits include:

Cardiovascular Recovery

This allows the heart to rest and cells and tissue to be repaired. (MedlinePlus, 2017) This can help the body recover after physical exertion. As an individual progresses through the stages of sleep, the changes in heart rate and breathing throughout the night promote cardiovascular health (National Heart, Lung, and Blood Institute, 2011)

Illness Prevention

The proper amount of sleep helps the body recover from illness. During sleep, the body produces cytokines/hormones that help the immune system fight off infections. These therapeutic effects are important for an athlete’s recovery and performance.

Lack of Sleep Affects Performance

Poor quality and quantity of sleep can lead to several negative effects. Sleep deprivation reduces the ability to react quickly and think clearly. A lack of sleep also increases irritability and risk for anxiety and depression. Sleep-deprived individuals are more likely to make poor decisions and take unnecessary risks. From a physical standpoint, a lack of sleep increases the risk for medical concerns, including type 2 diabetes, high blood pressure, kidney disease, and stroke. When athletes do not receive adequate sleep, it can:

Inhibit Ability

• In a study of sleep-deprived male team athletes, average and total sprint times decreased. (Skein, M. et al., 2011)

Decrease Accuracy

• In a study, male and female sleep-deprived tennis players had decreased serve accuracy by up to 53% compared to performance after normal sleep. (Reyner L. A. & Horne J. A. 2013)

Cause Quicker Exhaustion

• A study of male runners and volleyball players found that both athletes exhausted faster after sleep deprivation. (Azboy O. & Kaygisiz Z. 2009)

Decrease Reaction Time

• A study found that lack of sleep adversely affected reaction time in a group of male collegiate athletes. (Taheri M. & Arabameri E. 2012)

Difficulty Learning and Decision Making

• A lack of sleep negatively impacts cognitive skills and functions.
• Athletes can become distracted, and decisions like passing the ball or going for the smash can be difficult or made too late.

Increases Risk of Injury

• Research on middle—and high-school athletes showed that chronic lack of sleep was associated with increased rates of injury. (Milewski M. D. et al., 2014)

Increases The Risk of Illness or Immunosuppression

• Poor sleep habits are associated with lower resistance to illness like a cold. (Prather A. A. et al., 2015)

Athletic Sleep Hygiene

Common components to sleep well include:

Avoid alcohol and Caffeine

• Before bedtime, these can interrupt sleep or lead to more disturbed sleep.

Have a Wind-Down Routine

• Activities such as reading, bathing, or meditating can help the body relax and get ready for sleep.

Reduce Stressors

• Not only do mental stressors affect sleep quality, but they also impact performance overall.

Create an Optimal Sleep Environment

• A sleeping space should be dark and cool with little to no noise.
• The environment should be used only for sleep and sex.

No Electronics Before Bed

• This includes TVs, cell phones, and computers.
• The blue light that these devices emit can affect circadian rhythm.

Don’t Stay Awake In Bed

• If you can’t fall asleep after 20 minutes of trying, get out of bed.
• Do a quiet activity in another space until you feel sleepy.

Avoid Overtraining

• Keep a consistent training schedule so as not to overexert yourself.

Quick Naps

• Keep naps brief. Naps should be longer than an hour and not after 3 p.m.
