Two Time Zones, Two Matches, Five Hours of Sleep
An outside hitter on a women's volleyball team is in week three of a five-week road stretch. She is 21, a starter averaging 4.1 sets per match, and the team plays Friday and Saturday at 7:00 p.m. in a venue two time zones east of campus. Travel days begin with a 5:15 a.m. bus to the airport. She reports falling asleep around 1:00 a.m., waking at 5:30 a.m., and crashing with a two-hour nap most afternoons. She drinks three espresso shots at about 5:00 p.m. before matches and has started taking 3 mg of melatonin at 11:00 p.m. to knock herself out. Her sleep diary shows 5.2-5.9 hours in bed on the road against 8.0 at home; her readiness questionnaire score has fallen six points in three weeks. She reports feeling wired but exhausted and has had two uncharacteristic error-heavy matches. She denies pain, illness and medication use apart from the melatonin. Her coach wants her fixed by Friday.

Ranked contributors
- Sleep duration and timing, not sleep quality. 5.2-5.9 hours in bed on the road against 8.0 at home is a restriction of more than two hours a night for three weeks. That magnitude of debt reliably raises perceived effort, slows reaction time and degrades skill execution - which fits two error-heavy matches.
- Caffeine timing. Three espresso shots is roughly 190-200 mg. With a half-life near five hours, about half is still circulating at 10:00 p.m. and roughly a quarter around 3:00 a.m., which matches a 1:00 a.m. sleep onset and the wired-but-exhausted description. The caffeine is not the problem; the clock time is.
- The two-hour afternoon nap. A long nap close to the intended sleep window reduces homeostatic sleep pressure and pushes bedtime later, which then increases the need to nap. It is a loop, not a solution.
- The melatonin practice. 3 mg at 11:00 p.m. for a 1:00 a.m. attempt is a large dose used as a sleeping pill rather than a clock signal, and it is a supplement that should be third-party tested and cleared by the team physician.
- Eastward travel. Two time zones east leaves the body clock behind local time, so a 7:00 p.m. match feels like 5:00 p.m., and 5:15 a.m. departures compound the restriction.
What is not contributing. There is no pain, illness or medication, and no red flag on her health screen. This is a scheduling and behaviour problem rather than a medical work-up - unless the insomnia persists or mood changes appear, at which point the calculus changes.
2. Build the plan for the travel and match days, using caffeine, napping and melatonin correctly.

Anchor the wake time. Fix a consistent wake time at the destination and count backwards to an 8-9 hour sleep opportunity. On a 7:00 p.m. match night, a 12:00-1:00 a.m. bedtime is realistic, so wind-down starts around 11:15 p.m.
Caffeine, retimed rather than removed. Keep the ergogenic benefit and move it earlier. Last caffeine 8-10 hours before intended sleep means nothing after roughly 2:00-3:00 p.m. if bedtime is 1:00 a.m. If she wants a pre-match dose, use 1-3 mg/kg (roughly 60-190 mg) around 4:00 p.m., accept a small residual, and pair it with a strict wind-down. No caffeine after the match, including in recovery products.
Naps. Replace the two-hour afternoon nap with 20-30 minutes before 2:00 p.m., or a single 90-minute nap early enough to leave at least seven hours before bedtime. Short naps restore alertness without consuming the night.
Melatonin, if the team physician approves. 0.5-1 mg, 30-60 minutes before the target bedtime, for the first 3-5 nights in the new time zone - a clock signal rather than a knockout dose. Pair it with 30 minutes of outdoor morning light at the destination, a dark cool room, eye mask and earplugs for hotel noise.
After the match. A small carbohydrate-plus-protein snack, no caffeine, and a fixed routine so post-match arousal does not become a 1:00 a.m. habit.
Track it. Sleep duration and timing from her diary or wearable, bedtime consistency, and the readiness score trend. Change one variable at a time so we know what worked.
3. What do you tell the coach, what do you measure, and where does your scope end?

Message to the coach. Be concrete without overpromising: she is not broken, she is sleep-restricted and over-caffeinated at the wrong time of day. We have changed her caffeine cut-off, nap length and wind-down routine, and we are tracking it. I cannot promise a number by Friday, but I can say what will be different and how we will know. Emphasise that match-day caffeine stays - it is legal and effective - so the message is retiming, not removal. Coaches hear restriction better when the performance tool is preserved.
What to measure. Sleep duration and timing from her diary or wearable; her readiness questionnaire trend; hitting efficiency and error rate from the box score; and session and match RPE. Agree in advance that a two-to-three-week trend is the indicator, not a single match, so one bad night does not become a crisis.
Where scope ends. Sleep hygiene, travel scheduling and caffeine timing are within a performance coach's remit. Diagnosing insomnia, prescribing melatonin, or managing possible anxiety or depression is not. Persistent insomnia beyond roughly three weeks, low mood, or any suggestion of a sleep disorder means referral to the team physician or sport psychologist - and I would say so to the coach before the conversation, so referral does not look like a retreat under pressure.
