Key Takeaways

  • Light therapy glasses use targeted blue light to regulate circadian rhythms, improving sleep quality, eliminating jet lag faster, and boosting energy levels.
  • Elite athletes like LeBron James and Olympic teams such as the Spanish women’s hockey team use light therapy glasses strategically. They integrate 20-minute daily sessions into training routines and travel preparation for measurable competitive advantages
  • Morning use helps shift sleep schedules earlier and increases alertness, while evening use delays sleep timing for late competitions. The key to success is consistent daily usage with proper timing rather than sporadic application.

Poor sleep quality, persistent jet lag, and energy crashes during training can derail even the most dedicated athletic performance.

These circadian rhythm disruptions affect more than how you feel—they directly impact reaction times, recovery speed, and competitive results.

Light therapy glasses provide a portable, science-backed solution for optimizing your body’s internal clock.

Whether you’re battling morning training fatigue, struggling with travel schedules, or looking to gain a competitive edge through better recovery, light therapy glasses offer a practical tool that fits seamlessly into any training regimen.

Did you know?
Nearly every tissue and organ in humans has its own circadian rhythm, all synchronized by the master clock in your brain.

What Are Light Therapy Glasses?

Light therapy glasses are wearable devices that deliver controlled doses of specific light wavelengths directly to your eyes.

The devices emit blue light (around 470-480 nanometers) or blue-green light (500-520 nanometers) at carefully calibrated intensities.

This targeted light exposure helps regulate melatonin production and optimize circadian rhythms, enhancing energy levels and improving sleep quality.

Most models feature LED panels positioned above or around the eye area, casting light into your peripheral vision without blocking your sight.

Modern versions, like AYO’s, use refractive technology to deliver light therapy at lower intensities than traditional 10,000-lux light boxes, making them more comfortable for extended use.

The Science Behind Light Therapy for Athletes

Your body operates on a 24-hour internal clock controlled by a small brain region called the suprachiasmatic nucleus (SCN).

This “master biological clock” regulates hormone production, sleep-wake cycles, and complex behaviors through rhythmic neural activity generated by specific genes.

Light is the primary signal that keeps this internal clock synchronized with the external world.

When light enters your eyes, it travels through visual and non-visual pathways to reach the SCN.

This exposure suppresses melatonin production during the day, making you more alert, and allows natural melatonin release at night for quality sleep.

For athletes, this system becomes critical because physical performance fluctuates dramatically based on circadian timing.

Research from the University of Birmingham found that an athlete’s personal best performance requires consideration of their circadian phenotype and the time of day they’re competing.

Sleep-deprived tennis players showed decreased serve accuracy of up to 53% compared to normal sleep, while athletes getting 10+ hours improved accuracy by 10%.

Performance Benefits for Athletes

Light therapy glasses deliver measurable improvements across four critical areas of athletic performance, backed by research and real-world application data.

Sleep Quality Improvement

Light therapy significantly enhances morning alertness during training sessions by suppressing melatonin production, helping you wake up naturally and feel more alert.

Athletes using these devices report falling asleep faster, experiencing deeper sleep stages, and waking up more refreshed.

The sleep architecture improvements directly translate to better recovery.

During deep sleep, your body releases growth hormone, repairs muscle tissue, and consolidates motor learning from training sessions.

Enhanced sleep quality also means these recovery processes operate at peak efficiency.

Jet Lag Management

Professional teams have discovered that proper light therapy can reduce jet lag adaptation time from the typical one hour per day to significantly faster recovery.

Athletes using light therapy glasses before and during travel can prevent the fatigue and disorientation that typically follows time zone changes, arriving at destinations feeling energized rather than depleted.

This becomes crucial for athletes with demanding competition schedules.

Instead of losing several days to jet lag recovery, proper light therapy protocols allow immediate training resumption and competition readiness.

Energy and Mood Enhancement

Light therapy sessions increase energy levels and alertness, working like natural sunlight to suppress daytime melatonin production.

This proves particularly valuable during winter when reduced natural light can trigger seasonal mood drops affecting training consistency.

Athletes training in northern climates or spending extensive time in indoor facilities benefit from maintained energy levels throughout darker seasons, preventing the motivation and performance dips commonly associated with seasonal affective patterns.

Cognitive Performance

Research demonstrates that blue-enriched light exposure improves attention, memory, and reaction times —all critical components of athletic performance.

These cognitive enhancements prove especially important in sports requiring tactical decision-making, quick reactions, and complex skill execution.

The combination of improved focus and faster processing speed can provide the mental edge that separates good athletes from elite performers in high-pressure competitive situations

Did you know?
Use light therapy within 30 minutes of waking to shift sleep earlier (ideal for early training) or 2-3 hours before desired bedtime to delay sleep (perfect for evening competitions).

Real-World Athletic Applications

Professional sports organizations have quietly integrated light therapy glasses into their performance protocols, with results that demonstrate their practical value beyond laboratory studies.


Throughout the years, AYO has been used by numerous top-level and Olympic athletes, including American basketball player LeBron James and his coach. This represents a significant endorsement from one of the most performance-focused athletes in professional sports.


During the Tokyo 2020 Olympics, the Spanish women’s hockey team (the Redsticks) used AYO light therapy glasses while working with sleep specialists to improve their performance and overcome jet lag without leaving Spain.


The main goal was to adapt their internal biological rhythms to the Tokyo timezone before they traveled to the destination, and the team had been using the technology for several months during training.

How to Use Light Therapy Glasses Effectively

Successful light therapy requires precise timing and consistent application.

The key is to understand when and how long to expose yourself to light based on your specific circadian goals.

Timing Protocols

For delayed sleep phase syndrome—common among athletes who struggle falling asleep at conventional times—light must be delivered as soon after spontaneous awakening as possible to achieve the desired effect.

This typically means using light therapy glasses within 30 minutes of waking up.

Morning sessions work best for athletes who:

  • Have difficulty waking up early for training
  • Feel groggy during morning workouts
  • Want to shift their sleep schedule earlier
  • Are traveling eastward across time zones

On the other hand, evening light therapy helps move sleep and wake times later, making it useful for athletes with advanced sleep-wake phase disorder or those traveling westward.

Use light therapy for 20-40 minutes before your desired bedtime.

Evening protocols benefit athletes who:

  • Compete in late-night events
  • Need to stay alert for evening training sessions
  • Are traveling westward
  • Fall asleep too early for their competition schedule

Duration and Intensity Guidelines

AYO devices deliver effective results with just 20-minute daily sessions at 470-475nm wavelength with 250 μW/cm² irradiance.

This makes them easily manageable within busy training schedules.

Start with lower intensity settings and gradually increase as your eyes adapt.

The AYO app provides personalized programs based on your sleep habits and lifestyle, automatically adjusting timing and duration for your specific needs.

Higher intensity doesn’t always mean better results—consistency and proper timing matter more than maximum brightness.

The device’s three brightness settings (low, medium, high) allow you to find your optimal level without overexposure.

Integration with Training Schedules

Pre-Training Sessions: Use AYO glasses 30-60 minutes before morning workouts to enhance alertness and reduce sleep inertia effects.

Post-Training Recovery: Avoid light therapy immediately after intense evening sessions, which can interfere with natural recovery processes.

Travel Days: The AYO’s portable design makes it ideal for flights or immediate use upon arrival, depending on your destination’s time zone relative to your origin.

Your Next Performance Edge

Light therapy glasses provide athletes with a scientifically proven method to optimize sleep quality, eliminate jet lag faster, and maintain consistent energy levels throughout demanding training schedules.

Start with 20-minute morning sessions using a quality device like AYO to experience immediate improvements in alertness and long-term benefits in recovery optimization.
