west · severe- 13h — a major shift. Get bright morning sunlight at the destination for 2–3 days to reset your clock.
- Westward flights feel easier — stay active through the afternoon and sleep at local bedtime.
- Morning arrival — drop bags and walk 2–3 hours in daylight to reset your body clock.
- In-flight: 150 ml water per hour, skip coffee/alcohol, and walk the aisle every 3 hours — helps with both DVT risk and jet-lag fatigue.
