Cross-country tournaments and international showcases involve significant time-zone changes. A kid who flies from Seattle to a Florida tournament has a 3-hour shift. East-coast-to-Europe travel is 5 to 9 hours. The published research on jet lag in athletes is consistent: performance drops measurably when adjustment is incomplete, and the protocol that minimizes the drop is specific.
This piece is the framework for adolescent athletes traveling for competition.
The basics, briefly.
Jet lag is the mismatch between the body’s internal circadian clock and the local time at the destination. The body’s clock is regulated by light exposure, eating patterns, and physical activity, with some genetic individual variation.
The general rule from sleep-medicine research: adjustment takes approximately 1 day per time zone crossed for full alignment. A 4-hour shift takes roughly 4 days; a 6-hour shift takes 6.
Eastward travel (Seattle to New York, U.S. to Europe) is harder than westward travel because the body adjusts forward more slowly than backward.
For athletes, performance impairment from jet lag includes:
Slower reaction time.
Reduced power output.
Reduced cardiovascular efficiency.
Reduced cognitive performance and decision-making.
Disrupted sleep producing cumulative fatigue.
Effects last until adjustment is complete.
The pre-travel protocol.
Begin shifting sleep and meal times toward the destination’s schedule before departure, when feasible. For a 3-hour eastward shift, going to bed and waking 30 to 60 minutes earlier for 3 to 5 days before departure produces meaningful pre-adjustment.
For competitive trips with 1 to 4 time-zone shifts, modest pre-adjustment is usually enough. For larger shifts (5+ hours), pre-adjustment matters more.
Increase exposure to morning light in the days before eastward travel. Decrease evening screen exposure.
Day-of-travel.
For long flights, the goal is to arrive as well-rested as possible.
If the flight crosses sleep hours, attempt to sleep on the plane. Eye masks, earplugs, comfortable clothing. Older kids who can sleep upright benefit.
Avoid alcohol (not relevant for youth athletes but worth noting for parents) and minimize caffeine to allow sleep.
Stay hydrated. Airplane cabin air is dry; dehydration compounds fatigue.
Move every 60 to 90 minutes during the flight. Calf raises, walking the aisle.
Arrival protocol.
Light exposure manages the circadian clock most effectively.
For eastward travel (arriving in a time zone ahead of home):
Get morning light at the destination for 1 to 2 hours within the first day. Outdoor light is best; bright indoor light helps if outdoor is not possible.
Avoid evening light at the destination during the first 2 to 3 days. Sunglasses and reduced screen use in the evening at the destination.
The combination shifts the clock forward.
For westward travel (arriving in a time zone behind home):
Avoid morning light at the destination for 1 to 2 days.
Get evening light.
The combination shifts the clock backward.
Both protocols work but require deliberate scheduling.
The melatonin question.
Melatonin is available over-the-counter and is widely used for jet lag. The published evidence:
Modest evidence for adult use to assist sleep adjustment.
Limited evidence for adolescent use. The American Academy of Pediatrics (AAP) has called for more research and recommends discussing use with a pediatrician before regular use.
Typical adult doses range from 0.3 to 5 milligrams 30 to 60 minutes before the desired bedtime at the destination. Lower doses (0.3 to 1 milligram) are often as effective as higher doses with fewer side effects.
For adolescents, consultation with the pediatrician is the appropriate path. Short-term use for occasional travel is generally safe for most kids per AAP, but the conversation should happen with a clinician.
Sleep at the destination.
The destination room should be:
Dark. Blackout curtains or eye mask.
Cool. 65 to 68°F is the published optimal range for sleep.
Quiet. Earplugs or white-noise machine.
For team trips, room assignments should respect kids’ adjustment needs. Late-night activities in adjacent rooms disrupt sleep.
The training schedule at the destination.
For pre-tournament arrival, the schedule should:
Start with shorter and lighter sessions on the first day after arrival.
Build to full intensity over 2 to 4 days for moderate shifts.
Time hard training for what feels like late morning or early afternoon at the destination. This is generally when adjustment-impaired athletes perform best.
For East-coast US teams traveling to West-coast tournaments, evening competitions (which are afternoon body time) are often easier than morning competitions.
The competition day.
Adequate warm-up matters more when jet-lagged. The body needs more activation time.
Hydration matters more.
Pre-competition routine should be normal, not modified, even though local time may feel different.
Fueling on local schedule helps the body adjust.
For team managers.
Trip planning should include arrival timing relative to first competition.
For tournaments with multi-day schedules, the team that arrives 1 to 2 days early has a documented competitive advantage over teams that arrive day-of.
For short trips where arriving early is not feasible, scheduling lighter competition on the first day (when possible) is the alternative.
For families with kids on travel teams.
The post-tournament return trip also produces jet lag, particularly for travel back westward. The kid returning home from a Florida tournament back to Seattle on Sunday night faces school Monday with a sleep deficit and time-zone re-adjustment.
The realistic framing: school performance and energy on the return week may be reduced. Plan accordingly.
For high-stakes academic timing (exams, major projects), avoid scheduling tournaments in the week before.
The honest read. Jet lag is one of the more-manageable challenges of competitive travel when families and programs plan for it. The published protocols are clear; the implementation requires deliberate scheduling rather than improvisation. For one-time small trips, jet lag mostly resolves itself with adequate sleep and time. For competitive travel where performance matters, the structured protocol provides a documented edge.
For families considering whether to commit a kid to a heavily-travel-dependent program, jet-lag accumulation across a season is a real factor in cumulative fatigue, school performance, and overall health.
