Log sleep on local calendars, expect messy weeks, and use caffeine cutoffs carefully across zones.

Local calendar wins
Zeal day keys follow local dates on the device. That means an overnight flight splits across two days, and that is acceptable. Do not rewrite history to please a chart.
Capture duration and a rough quality note when you can.
First three nights
Expect fragmentation. Log naps if they matter to you; otherwise focus on main sleep. Targets can loosen while you adapt—perfection is a bad travel companion.
Light exposure and meal timing help many travelers; they are general tips, not medical protocols.
Caffeine across zones
Your cutoff hour may need a temporary shift. Update it in Settings for the trip, then restore it when you return. Logging coffee still helps you see if afternoon cups are stealing the next night.
Alcohol on arrival nights often backfires for sleep—optional social log can remind you gently.
Meals and water on planes
Cabin air is dry. Pair this guide with hydration and travel food logging. Airport meals deserve estimates, not abandoned journals.
Offline logging survives spotty gate Wi‑Fi.
Returning home
Give yourself a few days before judging trends. Compare the second week home, not the first forty-eight hours.
If jet lag symptoms are severe or unusual, talk to a clinician—especially with sleep disorders or medication schedules.
Keep the tone soft
Travel weeks are for records, not report cards.
Eastbound versus westbound expectations
Many travelers find eastbound trips harder on sleep timing. Your journal does not need the aviation theory—only honest durations and a note of direction if you like patterns later.
Force-fitting home bedtime on night one often backfires. Shift gradually when you can.
Melatonin and other aids are medical choices—ask a clinician or pharmacist; Zeal will not dose you.
Work trips versus vacations
Work trips squeeze sleep for meetings. Log what you got; loosen step and workout goals without drama.
Vacations may include late dinners and walking. Capture both so the week makes sense when you home.
Hotel gyms pair with the indoor workout guide when parks are far.
Re-entry week checklist
Restore caffeine cutoff, water target, and bedtime hour within two days of return when possible.
Expect one noisy sleep chart. Judge trends after seven local nights.
If shift work or clinical sleep disorders are involved, prefer specialist guidance over generic jet-lag blogs.
