TravelLast trip: landed as a zombie for 3 days. This time: shifted sleep 1 hour/day for 5 days before. Morning light. Meals at destination time. Landed and functioned. Same flight. 5 days of prep replaced 3 days of zombie.

Plan ready in under 90 secondsThe Problem
Eight timezone shift. Three lost days. Your body shifts 1 hour per day. Start 5 days early. Arrive with a 3-hour gap, not 8.
You fly across 6–12 timezones. You know what's coming: zombie for 2–5 days. Awake at 3 AM. Asleep at lunch.
Jet lag is a clock problem. Your body is set to home time. The gap is closeable BEFORE you board — shift 1 hour/day for 3–5 days = arrive 60–70% adjusted.
Morning light shifts your clock forward (eastward). Evening light shifts it back (westward). 20 min of sunlight beats any supplement.
Light is the #1 circadian signal. Starting the shift 5 days before eliminates 5 of 8 hours of jet lag. You land with a 3-hour gap instead of 8. Functional Day 1.
You need: a sleep schedule, a light plan, meal/caffeine timing, and an on-flight protocol. Not vague tips.
Day-by-day, hour-by-hour: when to sleep, when to seek light, when to eat, when to stop caffeine, and when to sleep/wake on the plane.
5 signals reset the clock: sleep timing, light exposure, meals, caffeine, and optional melatonin. All 5 together = fastest shift.
Pre-shift + on-flight protocol = arriving with most adjustment done. Business trip: productive Day 1. Vacation: enjoy Day 1, not sleep through it.
What You Get
Not 'take melatonin on the plane and hope.' 5 days of 1-hour shifts. Morning light. Meal timing. Arrive functional Day 1.
Pre-Flight Sleep Schedule
Day-by-day: bedtime and wake time shifted 1 hour per day toward destination. Start 3–5 days before. Your specific shift for YOUR route.
Light Exposure Plan
Each day: when to seek 20–30 min bright light (morning for east, evening for west), when to avoid it, and what type (sunlight > 10K lux lamp > screen).
Meal and Caffeine Timing
Meals shifted to destination times 2–3 days before. Caffeine: strategic for alertness at destination day, stopped 6–8 hours before destination bedtime.
On-Flight Protocol
Set watch to destination at boarding. Sleep during destination night (eye mask, earplugs). Stay awake during destination day. No alcohol (disrupts sleep quality).
Jet Lag Profile
Direction (east harder than west), magnitude (hours), predicted severity, adjustment days needed, and your specific vulnerability factors.

How It Works
From '3 days of zombie' to '5 days of 1-hour shifts. Morning light. Functional Day 1. Fully adjusted Day 2.'

AI builds the jet lag prevention plan
Our circadian engine calculates the shift, builds the day-by-day schedule, times the light exposure, and creates the on-flight protocol.
~15 seconds3
5 days before: shift bedtime 1 hour. Morning light. Repeat. Board the plane already 5 hours adjusted. Arrive functional.
Tonight: bed 1 hour earlier (east) or later (west). Tomorrow morning: 20 min outside sunlight. Shift meals toward destination times. Day by day, the gap closes. By flight day: 3–5 hours already shifted. You land functional. Not because of luck. Because of protocol.

Questions
Everything you need to know.
Does this really work?
YES — established circadian science. The body adjusts ~1 hour/day with the right signals. 5 days of pre-shifting = 5 fewer hours of jet lag. Studies show pre-adapted travelers report 50–70% less jet lag severity.
Why is eastward harder than westward?
Your body's natural clock runs ~24.2 hours. Delaying (staying up later = westward) is natural. Advancing (sleeping earlier = eastward) fights the clock. Eastward needs more aggressive light + sleep protocol.
Should I take melatonin?
Optional but effective. 0.5–3 mg, 30–60 min before TARGET bedtime (destination time), starting 3–5 days before. Signals 'prepare for sleep.' Timing matters more than dose. Consult your doctor.
What if I can only adjust for 2–3 days, not 5?
Still valuable. 3 days = 3 hours shifted. For an 8-hour shift: you arrive with a 5-hour gap instead of 8. That's the difference between 'rough but functional' and 'completely useless for 3 days.'
What about the on-flight melatonin and sleeping pills?
Melatonin on-flight: take it if destination nighttime and you want to sleep. Sleeping pills: avoid (they sedate but don't shift your clock, and impair cognitive function post-landing). Real sleep via melatonin + eye mask + earplugs > pill-induced unconsciousness.
Reviews
