Introduction: Why Sleep for Athletes Is a Performance Variable, Not a Lifestyle Choice
Sleep is an important recovery and performance variable for athletes, yet in my experience it is routinely undervalued. I see this often in clinical practice: athletes and active patients may track training load, nutrition, supplements, body composition, and recovery metrics in great detail, but still treat sleep as something flexible — something that can be compressed when life, training, or competition demands it.
Sleep is also a deeply sensitive part of human health. Sleep disorders are common, and they can affect almost every dimension of a patient’s quality of life, from daily functioning and mood to physical recovery and athletic performance. Many patients come to my clinic looking for a quick solution to sleep problems, often hoping for medication, while at the same time underestimating how much poor sleep is affecting them.
This pattern is especially relevant in athletes. Despite needing more sleep than the general population, athletes consistently fall short. A narrative review of the literature found that athletes may require about 9 or 10 hours of sleep, compared to the regular recommendations of seven to nine hours for adults, yet studies consistently report average sleep durations of less than 8 hours per night across age groups and disciplines [1].
My clinical approach starts from the idea that sleep symptoms should be taken seriously, but not automatically medicalized with medication. The first-line approach to many sleep problems is non-pharmacological. There is often a great deal that can be done before medication is considered: improving sleep timing, addressing cognitive arousal, modifying training or evening routines, screening for contributing health problems, and treating the specific sleep disorder when one is present.
At the same time, sleep symptoms should not be dismissed as “just stress.” In some cases, a more detailed sleep assessment is necessary, and this may reveal clinically significant sleep disorders such as obstructive sleep apnea, restless legs syndrome, or circadian rhythm disorders. Psychological and behavioral sleep problems are common, but careful evaluation is what allows the clinician to distinguish them from conditions that require targeted investigation and treatment.
In this article, I cover the full landscape of sleep for athletes: what the research says about sleep quality in athletic populations, the most common sleep disorders that affect athletes, how disrupted sleep translates into impaired performance, and what evidence-based interventions — including the clinical approach I use with my own patients — actually work.
How Common Are Sleep Problems in Athletes?
The data on athlete sleep are consistent across sports, levels, and measurement tools — and consistently concerning.
According to a synthesis of the available literature, the average sleep length in elite athletes calculated by actigraphy was around 6.5 hours; 39.1% of athletes self-reported having inadequate sleep, defined as less than seven hours; and the average number of nights per week in which athletes felt they did not get sufficient sleep was 3.8. The quality of sleep assessed through the Pittsburgh Sleep Quality Index (PSQI) showed that 19.8% to 50% of participants in various studies exhibited a score >5, suggesting poor sleep quality [1].
A cross-sectional survey of current and former athletes across seven countries found that self-reported sleep disorders were observed in 25.4% of current athletes and 30.9% of former athletes [10]. In one study of 175 elite and highly trained rugby, rugby sevens, and cricket athletes, 50% were found to be poor sleepers (PSQI >5), and clinically significant daytime sleepiness (ESS score ≥10) was present in 28% of athletes [9].
These figures matter because the stakes are high. Reviews report associations between sufficient sleep quality and several performance-related outcomes in elite athletes, including higher accuracy, faster reaction times, increased physical endurance, improved cognitive performance, and psychological resilience [1].
In my clinical work with athletes, I try to separate two different problems early. Sometimes the issue is not a formal sleep disorder, but a lack of sleep opportunity. The athlete may go to bed too late, wake up too early, or simply fail to protect enough time for sleep. In those cases, the problem is often practical: scheduling, training demands, evening routines, or not fully understanding how strongly sleep affects recovery and performance.
But I also see the opposite situation. Some athletes genuinely want to sleep, have created enough time for sleep, and still cannot fall asleep or stay asleep. At that point, I do not treat the problem as a matter of discipline or motivation. These athletes can have the same real sleep disorders as any other patient — insomnia, sleep apnea, restless legs syndrome, circadian rhythm problems, or other conditions that require proper assessment and targeted treatment.
This distinction matters. Some athletes mainly need education, better scheduling, and a clearer understanding of sleep as part of recovery. Others need a clinical evaluation, because the problem is not that they are careless with sleep — it is that they cannot sleep normally despite trying.
What Poor Sleep Does to Athletic Performance
The performance consequences of sleep deprivation are increasingly well documented, and several plausible physiological mechanisms have been described.
A 2025 systematic review and meta-analysis including 45 studies quantified the effects precisely: sleep deprivation significantly impaired aerobic endurance in athletes [SMD = −0.66; 95% CI (−1.28, −0.04); P = 0.04], as well as explosive power [SMD = −0.63; 95% CI (−0.94, −0.33); P < 0.00001], maximum force [SMD = −0.35; 95% CI (−0.56, −0.14); P = 0.001], speed [SMD = −0.52; 95% CI (−0.83, −0.22); P = 0.0008], skill control [SMD = −0.87; 95% CI (−1.7, −0.04); P = 0.04], and ratings of perceived exertion [SMD = 0.39; 95% CI (0.11, 0.66); P = 0.006] [2].
A scoping review describes sleep deprivation as being associated with increased catabolic hormonal activity — including elevated cortisol — and reduced anabolic hormonal signaling including testosterone and IGF-1. Growth hormone, which is produced during slow-wave sleep, is also altered by sleep deprivation, leading to changes in protein synthesis and proteolysis that affect muscle recovery [6]. This endocrine pattern is relevant to broader discussions of recovery markers, including cortisol and overtraining dynamics, the T:C ratio in overtraining, and cortisol in athletes. For a look at how morning cortisol patterns reflect recovery status, see my article on the cortisol awakening response in athletes.
The same scoping review concluded that an interpretation of the relationship of sleep deprivation with injury risk may include reduced concentration and attention, worsened reaction time and cognitive functions, and the sense of fatigue experienced by athletes [6].
Beyond athletic performance, poor or insufficient sleep affects the whole person. Many athletes are not only athletes: they study, work, maintain relationships, travel, and carry the same daily responsibilities as everyone else. When sleep deteriorates, these areas often suffer as well. Concentration becomes harder, emotional regulation weakens, motivation drops, and the athlete may begin to feel that recovery is failing not only in sport, but in life more broadly.
In my own patients, insomnia is often intertwined with mental health symptoms. Sometimes poor sleep is one of the first symptoms that brings a patient to my clinic, even before they have fully recognized the broader stress, anxiety, low mood, or overload behind it.
In many cases, sleep is the factor that finally breaks the camel’s back. A patient may tolerate fatigue, pressure, training stress, work, or study demands for a long time, but when sleep collapses, the whole system becomes harder to sustain. That is why sleep assessment should not focus only on performance metrics. It should also ask how the athlete is functioning as a person.
Why Athletes Sleep Poorly — The Main Drivers
Before diagnosing a specific sleep disorder, it is worth understanding the structural reasons why sleep for athletes is chronically disrupted.
Training load and scheduling. Early morning practice sessions, late-night competitions, and congested competition calendars all compress sleep opportunity. A systematic review found that risk factors for sleep and circadian rhythm disturbances in young adult athletes include early morning practice sessions, late night games, and jet lag [13].
Exercise timing and physiological arousal. Strenuous exercise is associated with delayed sleep onset, shorter sleep duration, lower sleep quality, higher nocturnal resting heart rate, and lower nocturnal heart rate variability. A large prospective study using biometric data from 14,689 physically active individuals across 4,084,354 person-nights found that later exercise timing and higher exercise strain are associated with these sleep disruptions, and that regardless of strain, exercise bouts ending ≥4 hours before sleep onset are not associated with changes in sleep [11].
Psychological arousal. A systematic review identified two underlying mechanisms implicated in sport-related insomnia symptoms: pre-sleep cognitive arousal and sleep restriction [7]. These are common targets in behavioral insomnia treatment.
Travel and circadian disruption. Rapid travel across multiple time zones is associated with a transient desynchronization of the body’s circadian rhythms, manifested as jet lag [14]. Jet lag symptoms can persist until the circadian system adapts to the destination time zone. For athletes competing internationally, the cumulative circadian burden across a season is substantial.
In my clinical experience, the mechanisms behind sleep problems in athletes are often the same mechanisms I see in other patients. The difference is that sport can make these mechanisms more difficult to manage. One of the clearest examples is sleep timing. When an athlete has late-evening training sessions, very early morning practices, competitions, or travel, the available sleep window may simply become too short, even if the athlete understands the importance of sleep and wants to sleep more.
I also pay close attention to physiological arousal. After hard training, the body is not always ready to downshift immediately into sleep. Some athletes describe feeling tired but still “wired,” especially when intense sessions take place close to bedtime. This is not unusual: training increases activation in the body, and for some athletes that elevated state can persist into the evening.
The psychological side matters just as much. Athletes do not only train their bodies; they also carry performance pressure, tactical thinking, self-evaluation, selection concerns, and competition anxiety. In that sense, sport can affect sleep in the same way demanding work or life stress affects sleep in other patients.
So when I assess an athlete with sleep problems, I do not assume the mechanism is completely unique. Often it is the same combination of timing, arousal, stress, and behavior that affects many people. What makes athletes different is the intensity and regularity of these pressures: training schedules, competition calendars, recovery demands, and travel can all amplify ordinary sleep vulnerabilities into a clinically meaningful problem.
Sleep Disorders in Athletes: The Complete Picture
Insomnia — The Most Commonly Discussed Sleep Problem in Athletes
Insomnia symptoms are among the most common sleep problems reported in athletes. A review reports insomnia symptoms in 27–37% of athletes, with sleep maintenance insomnia reported in 77% of athletes, based on cited athlete studies. The psychological demands of sport, performance anxiety, and overthinking delaying sleep behaviors can play a role in the development of these symptoms [4].
A systematic review found that athletes show a high overall prevalence of insomnia symptoms characterized by longer sleep latencies, greater sleep fragmentation, non-restorative sleep, and excessive daytime fatigue, with symptoms showing marked inter-sport differences [7].
In my clinical experience, many patients with insomnia have an underlying sensitivity to sleep disruption. This is not always a disease in itself, but more of an individual trait: some people simply have a more reactive sleep system than others. When life is stable, they may sleep reasonably well. But when chronic stress, illness, emotional strain, overtraining, travel, or another external trigger enters the picture, sleep can become much more fragile.
In these situations, the original trigger may improve, but the sleep system does not always return immediately to its previous baseline. In some patients, sleep never fully returns to the way it was before. They may remain more vulnerable to sleep disruption than they used to be, especially during periods of stress, illness, travel, or heavy training. This does not mean that the situation is hopeless, but it does mean that the clinical goal is often not to “force” sleep back to an old baseline. Instead, the aim is to rebuild confidence in sleep, reduce arousal around bedtime, stabilize routines, and help the patient manage a more sensitive sleep system.
This is one of the most common patterns I see in clinical practice, and it is especially relevant for athletes. A demanding training schedule, competition stress, illness, injury, or life pressure can trigger a period of poor sleep. If the athlete then becomes anxious about sleep itself, the problem may persist beyond the original trigger. In these cases, sleep hygiene, consistent routines, cognitive arousal management, and behavioral sleep interventions are often more useful than simply looking for a medication-based solution.
Obstructive Sleep Apnea in Athletes
Sleep-related breathing disorders (SRBD) are prevalent in certain athletic populations. A review reports that up to 45% of athletes have reported, or been shown to suffer from, OSA, although much of the sport-specific OSA literature has focused on collision sports [4]. A 2025 systematic review found that the frequency of SRBD (apnea-hypopnea index ≥5 events/hour) varied from 7% to 86.5% according to sport modality — from 24% to 86.5% in rugby players, 8% to 62.5% in active football players, 61% in ice hockey players, and 68% in judo athletes [3].
In athletes, SRBD/OSA has been associated with excessive daytime sleepiness and cognitive impairment, with risk factors including higher BMI, greater body weight, larger neck circumference, prior concussion history, and certain collision-sport playing positions [3].
SRBD is clinically important and treatable. Treatment with CPAP therapy improved sleep quality, reduced daytime sleepiness, and enhanced athletic performance among golfers and judo athletes; mandibular advancement device reduced apnea severity and snoring among rugby players [3].
Athletes with symptoms such as snoring, witnessed apneas, morning headaches, or excessive daytime sleepiness should be assessed for possible OSA/SRBD, even when classic risk factors are absent.
In general, the treatment pathway for sleep apnea depends on the severity of the condition and the suspected anatomical or functional contributors. In Finland, patients with clinically significant sleep apnea are often referred to a pulmonologist, as initiation of CPAP therapy is typically managed within respiratory medicine. However, not all cases follow the same route. If the patient has large tonsils, a narrow pharynx, or another suspected upper airway obstruction, consultation with an ear, nose, and throat specialist may be appropriate, especially when enlarged tonsils are a prominent finding. On the other hand, if the symptoms are clearly position-dependent, positional therapy may be considered as a first-line treatment. In milder cases, particularly when apneas occur mainly while sleeping on the back, patients may also be referred to a dentist for assessment of mandibular advancement device therapy, especially if CPAP is not indicated or is not the preferred initial option.
Restless Legs Syndrome, PLM, and the Iron Connection
Restless legs syndrome is a sensorimotor disorder defined by an irresistible urge to move the legs, typically worse at rest and in the evenings, temporarily relieved by movement. Periodic limb movement disorder (PLMD) is a related but distinct condition involving repetitive, stereotyped limb movements during sleep — often without the patient’s awareness. PLMS are found in up to 80% of restless legs syndrome (RLS) cases [18], making the two conditions clinically overlapping but diagnostically separable.
RLS is particularly relevant for sleep for athletes because iron deficiency is one of the most important secondary causes. A review notes that RLS is most commonly related to iron deficiency, pregnancy, and uremia, and that RLS symptoms show a significant circadian rhythm and a close relationship to periodic limb movements [15]. Because iron deficiency is a recognized secondary association of RLS, iron status assessment is clinically reasonable in athletes presenting with RLS symptoms — see my detailed breakdown of ferritin levels for athletes and iron panel interpretation for athletes.
For athletes with RLS, the relationship with exercise is nuanced. A nationwide survey of people with RLS found that perceived effects of exercise were mixed: the majority of respondents reported improvement, while a smaller group reported worsening. Abrupt changes in exercise routine may aggravate symptoms in some individuals, and the authors noted that exercise timing appeared relevant, with morning exercise more commonly perceived as beneficial [8].
In my clinical work, restless legs syndrome and periodic limb movement disorder often become apparent during sleep studies, usually through tibialis anterior EMG monitoring. When I see this pattern, one of the first laboratory values I usually check is ferritin. This is especially relevant in athletes, and particularly in female athletes, because iron deficiency may already be present even before sleep-related symptoms are investigated.
In some patients, iron supplementation alone can make a meaningful difference and may even resolve the symptoms if low iron stores are a contributing factor. However, this is not always enough. From time to time, I also need to consider medication for restless legs syndrome or periodic limb movement disorder. As with any pharmacological treatment, this should be assessed individually and discussed with the patient’s own doctor, taking into account the diagnosis, laboratory findings, contraindications, and the overall clinical situation.
Delayed Sleep Phase Disorder and Circadian Misalignment
Delayed sleep phase disorder is particularly problematic for athletes with early morning training schedules. One recent review reports that pre-competition insomnia, delayed sleep-phase disorder, jet-lag–related disturbance, and chronic sleep restriction may collectively affect 30–70% of athletes, though estimates vary by definition, sport, and competition context [16].
In my clinical experience, these problems are often more challenging in athletes who are naturally evening-oriented. If an athlete’s biological rhythm is already shifted later, early training sessions can create a repeated mismatch between when the body is ready to sleep and when the alarm clock demands wakefulness. Morning-oriented athletes often cope better with early schedules, partly because they tend to fall asleep earlier and usually have less difficulty waking up for morning training.
Less Common Sleep Disorders
Several rarer conditions appear in athletic populations and merit clinical awareness, though the peer-reviewed athlete-specific evidence base for each remains limited. Any clinical assessment requires specialist evaluation.
Narcolepsy — characterized by excessive daytime sleepiness, sleep attacks, and in some cases cataplexy — can be misattributed to overtraining or poor recovery, particularly given overlapping symptom profiles.
REM Sleep Behavior Disorder (RBD) involves the acting out of vivid dreams and may warrant specialist neurological assessment, particularly in athletes with a history of repetitive head impacts.
In my clinical experience, both narcolepsy and RBD are rare findings, but they are occasionally detected in comprehensive sleep studies. When these conditions are suspected or identified, I refer the patient for further assessment within neurology.
Upper Airway Resistance Syndrome (UARS) is a form of sleep-disordered breathing that may cause significant sleep fragmentation and fatigue without meeting formal OSA criteria, and may require specialist evaluation when standard polysomnography is unrevealing.
In my experience in Finland, these patients are most often referred for an ear, nose, and throat specialist assessment, especially when the clinical picture suggests upper airway narrowing or anatomical contributors that may not be fully captured by standard sleep apnea criteria.
How to Assess Sleep in Athletes: Practical Tools
Commonly used screening tools include the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). In athlete studies, PSQI >5 and ESS ≥10 are used as thresholds for poor sleep quality and daytime sleepiness. In a study of 175 elite and highly trained rugby, rugby sevens, and cricket athletes, 50% were found to be poor sleepers (PSQI >5), and clinically significant daytime sleepiness (ESS score ≥10) was present in 28% of athletes [9]. Formal sleep testing may be considered when clinically indicated.
Blood work — particularly iron status via ferritin levels for athletes — should be evaluated when sleep disturbance coexists with fatigue symptoms or RLS. Broader hormonal assessment, including thyroid markers should be individualized based on clinical findings. Athletes preparing for blood tests should read my guide on preparing for blood test athletes.
In our clinic, we use comprehensive sleep testing when symptoms suggest that a more detailed diagnostic assessment is needed. The study includes position sensors, tibial EMG, EEG, ECG, respiratory sensors, chin EMG, and oxygen saturation monitoring. This allows us to evaluate sleep architecture, breathing abnormalities, limb movements, arousals, oxygenation, body position, and cardiac rhythm during sleep.
In practice, this kind of assessment often gives us a much clearer explanation for the patient’s sleep problem than symptom history alone. It may reveal obstructive sleep apnea, periodic limb movements, restless legs–related findings, abnormal arousal patterns, circadian or behavioral contributors, or other clinically relevant sleep disturbances. At the same time, we can assess whether the problem is primarily insomnia, a breathing-related sleep disorder, movement-related sleep disruption, or a combination of several factors.
Evidence-Based Sleep Interventions for Athletes
Sleep Extension and Napping
Sleep extension is one of the best-supported sleep interventions studied in athletes. A 2023 systematic review found that extending sleep duration by 46–113 min in athletes that habitually sleep ~7 h per night may be a general recommendation for future sleep extension programs, and that supplementing sleep during the day with a 20–90-min nap can improve performance outcomes after a regular night and restore performance decrements to baseline levels after a night with partial sleep restriction [5].
For athletes with insomnia symptoms, napping is generally not recommended. Daytime naps can reduce homeostatic sleep pressure — the biological drive that helps sleep begin and continue at night — and this can make insomnia worse, especially in evening-type athletes who already tend to fall asleep late. In these patients, preserving sleep pressure until bedtime is often an important part of treatment.
Napping is better reserved for athletes who do not have ongoing sleep difficulties. For athletes managing temporary accumulated sleep debt without insomnia, short and carefully timed naps may be useful, but they should not come at the cost of nighttime sleep.
Managing Exercise Timing for Better Sleep
Where scheduling flexibility exists, athletes aiming to protect sleep may benefit from finishing high-strain exercise at least 4 hours before intended sleep onset or reducing intensity within that window [11].
Where possible, training should be scheduled for the afternoon or early evening after work or study, rather than too late at night. For many athletes, this timing works well physiologically: it prevents the post-work drop in alertness from turning into an early evening slump, while still allowing arousal to decline later in the evening in a more natural way.
Nutrition Timing and Sleep Quality
In a small study of 12 healthy men, a significant reduction in sleep onset latency was observed with a high-GI meal consumed 4 hours before bedtime (9.0 ± 6.2 min) compared with a low-GI meal (17.5 ± 6.2 min; P = 0.009) [12]. Whether this finding generalizes fully to athletic populations requires further study, but the data suggest that carbohydrate composition and meal timing in the pre-sleep window may be clinically relevant.
Regarding magnesium, observational studies have found associations between low magnesium status and reduced sleep quality, including delayed sleep onset and daytime sleepiness, though evidence from randomized controlled trials remains inconsistent [19]. See also my article on magnesium in athletes for the broader clinical picture.
In practice, I often advise patients to avoid a very heavy meal immediately after work or study, especially if they already tend to crash in the early evening. A large meal at that point can deepen the drop in alertness, and for some people this leads to a paradoxical pattern: they feel sleepy too early, rest or doze, and then become more alert again later in the evening when they should be winding down for sleep.
For these patients, a lighter meal or snack after work, followed by a more substantial evening meal later, can sometimes work better. The goal is to align the natural post-meal sleepiness with the later evening rather than the early evening. In some patients, this helps preserve daytime structure, avoid premature devening sleepiness, and support a more stable transition toward night-time sleep.
An evening-weighted dinner can also help create a clearer transition between the active part of the day and the night. I often advise patients to place this meal at a point when the day’s main responsibilities are finished, messages and work demands are no longer interrupting them, and they can genuinely start to slow down.
In that sense, dinner is not only about nutrition. It can become a behavioral anchor: a repeated signal that the day is ending and the body no longer needs to remain in problem-solving mode. For some patients, this kind of predictable evening routine helps reduce cognitive arousal, supports psychological downshifting, and prepares the body and mind for sleep.
Circadian and Pharmacological Management
For travel across time zones, pharmacological circadian support may be appropriate in some contexts. In general, melatonin is usually the first option considered when the goal is circadian adjustment rather than sedation. However, the timing, dose, and suitability of melatonin should still be individualized, because taking it at the wrong time can shift the circadian rhythm in the wrong direction or fail to help.
If symptoms are severe, travel demands are high, or there are additional sleep disorders, the athlete’s own physician may consider other pharmacological options after a careful clinical assessment. The risk-benefit profile depends on the specific sleep disorder, training schedule, competition calendar, medical history, and any relevant anti-doping considerations.
Cognitive Behavioral Therapy for Insomnia (CBT-I)
CBT-I is an evidence-based non-pharmacological treatment for insomnia, now recommended as first-line therapy for chronic insomnia. A meta-analysis of 30 randomized controlled trials found that CBT-I produces clinically significant effects at 3, 6, and 12 months compared to non-active controls, demonstrating effects that last up to a year after therapy [20]. Athlete-specific evidence is emerging: a study comparing CBT-I with cranial electrotherapy stimulation in athletes with pre-competition poor sleep quality found improvements in sleep quality and daytime sleepiness [17].
CBT-I targets perpetuating factors of insomnia — sleep-related anxiety, conditioned arousal, and unhelpful sleep beliefs — and includes components such as sleep restriction, stimulus control, and cognitive restructuring.
In practice, we often guide patients with insomnia toward structured sleep therapy. This may mean working with a therapist or psychologist trained in insomnia treatment, especially when cognitive arousal, stress, anxiety, or conditioned sleep-related worry is maintaining the problem.
In Finland, there are also good online therapy options for insomnia. Many patients experience these as a low-threshold form of support: they are easier to start than traditional face-to-face therapy, they provide clear structure, and they help patients understand the behavioral and cognitive patterns that keep insomnia going. For many people, this kind of guided online insomnia therapy can be a practical and effective first step before considering medication.
Treating the Underlying Cause
When OSA/SRBD is diagnosed, targeted treatments such as CPAP or mandibular advancement devices may be indicated; sleep hygiene alone is not a definitive treatment for airway obstruction. In athletes where RLS is associated with iron deficiency, correcting iron status is part of management, with specific supplementation thresholds guided by individual clinical assessment. Treatment for PLMD and other specific sleep disorders should be guided by a sleep medicine physician.
However, sleep disorders often overlap. A patient may have insomnia and obstructive sleep apnea, restless legs symptoms and periodic limb movements, or a combination of behavioral, respiratory, movement-related, and circadian contributors. This is one reason why a comprehensive sleep study can be clinically useful: it helps distinguish which mechanisms are actually disrupting sleep and whether several problems are present at the same time.
In practice, these conditions sometimes need to be treated separately, and sometimes as part of one broader sleep plan. For example, airway obstruction, iron deficiency, limb movements, cognitive arousal, and sleep timing may all require different interventions.
A Practical Framework for Sleep for Athletes: What to Prioritize
In my clinical work, I often start with wake time. A consistent wake time is one of the cornerstones of behavioral sleep management. When wake time is held constant daily — including weekends — sleep pressure builds more predictably toward the evening and bedtime often starts to shift earlier.
I also consider chronotype in individualized planning. Morning-type athletes usually tolerate early wake times well, while evening-type athletes naturally tend toward later sleep onset and longer morning sleep. For evening-type athletes with sleep onset difficulties, I often emphasize maintaining a consistent wake time — even when it feels uncomfortable at first — as a practical way to stabilize the circadian rhythm over time.
Many athletes may benefit from aiming above the general adult sleep minimum. Reviews suggest athletes may require around 9–10 hours for optimal recovery [1], and repeated sleep shortfalls may plausibly impair recovery and adaptation partly through the endocrine and protein-turnover pathways described in sleep-deprivation literature [6].
In practice, however, I usually emphasize wake time before bedtime. The most important anchor is often waking up at the same time every day. When wake time is stable, sleep pressure builds more predictably during the day, and the athlete often begins to feel sleepy earlier in the evening without needing to force it. Going to bed too early when the athlete is not actually sleepy is usually not helpful; it can lead to frustration, prolonged time awake in bed, and stronger sleep-related arousal. Aiming for more sleep should therefore mean creating enough sleep opportunity while still respecting the body’s actual readiness for sleep.
It is also important to remember that this adjustment does not always happen after one night. When wake time is stabilized, sleep pressure may begin to shift the rhythm over the next few nights rather than immediately. In practice, I often tell patients to think in terms of 1–4 nights instead of judging the plan after a single difficult night. This helps reduce frustration and prevents the athlete from changing strategy too quickly before the body has had time to respond.
Persistent fatigue, poor recovery, or unexplained performance decline should prompt sleep screening. PSQI and ESS are commonly used tools, and formal sleep testing may be considered when clinically indicated. In our clinic, when symptoms persist or the clinical picture is unclear, we have a low threshold for referring the patient for a comprehensive sleep study. This is especially important when there are symptoms suggesting sleep apnea, periodic limb movements, fragmented sleep, unexplained daytime sleepiness, or overlapping sleep disorders.
Where scheduling flexibility exists, high-intensity sessions should be completed at least 4 hours before intended sleep onset [11]. In practice, I often prefer training to take place after the work or study day, but not too late in the evening. For some athletes, this helps prevent the early-evening drop in alertness that can occur immediately after work, followed by a paradoxical rise in alertness later at night. An afternoon or early-evening training session can keep the rhythm of the day active, while still allowing enough time for physiological arousal to decline before bedtim
For pre-competition insomnia, perspective matters. An athlete who cannot sleep the night before a major competition is experiencing pre-sleep cognitive arousal. Avoiding sleep “effort,” allowing relaxed activity in bed, and not catastrophizing a single poor night is appropriate clinical guidance — the performance impact of a given poor night varies by task, sleep-loss severity, and timing.
It is also worth remembering that one poor night, or even a couple of poor nights, does not automatically ruin performance. During my own competitive career, I learned to see some disrupted sleep before major competitions as part of the process rather than as a disaster. Paradoxically, the less importance I gave to it, the easier sleep often became. Experience also helps: the more often an athlete competes, the more familiar the pre-competition state becomes, and the less threatening the occasional poor night of sleep may feel.
Any pharmacological sleep support should be determined by a physician with knowledge of the athlete’s full clinical picture, competition schedule, and anti-doping obligations. Melatonin is generally one of the lower-risk options and may be reasonable to consider, especially when the main issue is circadian timing rather than sedation. Athletes should still discuss its use with their own physician, particularly if they compete under anti-doping rules, use other medications, or have persistent sleep symptoms.
Conclusion: Sleep for Athletes as a Competitive Advantage
Sleep for athletes should not be treated as an optional recovery detail. It is part of the foundation that determines whether training actually becomes adaptation. Poor sleep can reduce performance, impair recovery, increase perceived effort, affect mood and concentration, and in some athletes reveal an underlying sleep disorder that requires proper diagnosis and treatment.
In my clinical work, I try to approach athlete sleep from two directions at the same time. First, I look at the practical structure: wake time, sleep opportunity, training timing, travel, nutrition, evening routines, and recovery habits. Many athletes can improve sleep significantly by stabilizing these factors. Second, I look for real sleep pathology. Insomnia, sleep apnea, restless legs syndrome, periodic limb movements, circadian rhythm problems, and overlapping sleep disorders are not solved by motivation alone. They require careful assessment and targeted treatment.
The most important message is that sleep problems should not be ignored, minimized, or treated only with quick pharmacological fixes. Athletes often need more than generic sleep hygiene advice, but they also do not always need medication as the first answer. A structured approach — protecting wake time, respecting sleep pressure, avoiding too-late high-intensity training, managing cognitive arousal, screening for sleep disorders, and using comprehensive sleep testing when needed — can make sleep a practical part of performance care.
As both a doctor and a former elite competitor, I see sleep as one of the clearest areas where medical thinking and athletic performance overlap. Better sleep is not only about feeling rested. It is about giving the nervous system, hormones, muscles, brain, and mind the conditions they need to recover. For athletes, learning to sleep well is not a luxury. It is a competitive advantage.
