Direction and time-zone change matter

Eastward and westward trips can feel different.

Light and local schedule are major cues

Daylight, meal timing and sleep timing help reset the body clock.

Do not over-schedule arrival day

A lighter first day gives room for poor sleep.

Medication or supplement advice is medical

Discuss those choices with a qualified health professional.

Verify before you go. Weather, entry rules, advisories, transport schedules, prices and local conditions can change. Use this page to structure your decision, then verify the current details that affect your specific trip.
