Sleep, but keep it controlled
High confidenceReduce sleep debt without sabotaging your first local night.
Sleep window: 4 hours 40 minutes - 9 hours after departure (max 4 hours 20 minutes)
First day plan: Go to bed soon after landing. Avoid caffeine. Avoid naps.
Why this recommendation?
- This is a long-haul flight (9h 45m), so unmanaged sleep debt is a major factor.
- You are traveling east across 2 hours, which usually requires advancing your body clock.
- Time-zone shift is small (2h), so jet lag pressure is limited.
Tips for your flight
- Hydrate consistently during and after the flight.
- Use caffeine early only; avoid it later in the destination day.
- Sleep in a bounded window, then wake and transition to destination timing.
- Get bright light exposure after landing to reinforce destination daytime.
- Limit bright light late in the evening to protect local bedtime.
- Go to bed soon after arrival if it is already local night.

Time Zone Change
Flying east squishes your perceived day - clocks at DXB are 2 hours ahead, so your day feels shorter than 24 hours. Your body will want to sleep and wake later than locals in DXB.
