Professional athletes constantly travel across time zones for competitions, making them experts in combating jet lag. Their livelihood depends on peak physical performance, regardless of travel fatigue. Elite sports teams and Olympic competitors have developed sophisticated strategies to maintain performance despite long-haul flights. These techniques, once exclusive to high-level sports, are now being adopted by business travelers and vacationers seeking to maximize their time abroad.
The science behind jet lag and athletic performance
Jet lag occurs when your body’s internal clock becomes misaligned with the local time at your destination. This circadian rhythm disruption affects multiple bodily functions, including hormone production, digestion, and temperature regulation. For athletes, even slight physiological imbalances can significantly impact performance.
Research published in the Journal of Sports Sciences indicates that eastward travel typically causes more severe jet lag symptoms than westward journeys. This happens because extending your day (traveling west) is easier for your body to adapt to than shortening it (traveling east).
The severity of jet lag typically corresponds to the number of time zones crossed:
- 1-2 time zones: Minimal adjustment needed
- 3-5 time zones: Moderate disruption requiring strategic intervention
- 6+ time zones: Significant disruption requiring comprehensive protocols
Professional teams like the NBA’s Golden State Warriors and Premier League football clubs employ sleep specialists who develop personalized travel plans based on individual chronotypes (whether someone is naturally a morning or evening person).

Strategic light exposure: the athlete’s secret weapon
The most powerful technique in the athlete’s jet lag arsenal is strategic light exposure. Light is the primary cue that regulates our circadian rhythms. By carefully controlling when they expose themselves to light and when they avoid it, athletes can reset their internal clocks faster.
Olympic teams from countries like Australia and Great Britain often arrive at competition venues up to two weeks early, implementing a precise light exposure protocol to shift their body clocks. This involves wearing special blue-light blocking glasses at specific times and using light therapy boxes during others.
The table below outlines a typical light exposure strategy for eastward travel across 8 time zones:
| Day | Morning | Afternoon | Evening |
|---|---|---|---|
| Pre-travel | Light exposure | Normal activity | Avoid bright light |
| Travel day | Avoid bright light | Limited light exposure | Avoid screens |
| Arrival day | Bright light exposure | Outdoor activity | Dim lights after sunset |

Hydration and nutrition timing strategies
Dehydration exacerbates jet lag symptoms, making proper fluid intake crucial for traveling athletes. Many follow the “drink before you’re thirsty” rule, consuming water consistently throughout flights.
Elite runners and triathletes often calculate their hydration needs using a formula based on body weight and flight duration. They typically aim for 8-12 ounces of water per hour in flight, avoiding alcohol and limiting caffeine.
Equally important is the strategic timing of meals. Team nutritionists create detailed eating schedules that align with the destination time zone, beginning this shift before departure. This helps signal to the body when it should be active or at rest.
Athletes also prioritize anti-inflammatory foods during travel, including:
- Tart cherry juice for melatonin production
- Omega-3 rich foods like salmon and walnuts
- Ginger and turmeric for reducing inflammation
- Complex carbohydrates for sustained energy
The US Women’s National Soccer Team famously travels with personalized nutrition plans that specify not just what to eat, but precisely when to consume each meal or snack relative to both departure and destination time zones.
