Quick Recovery Tips

Light Exposure Timing

Get bright morning light upon arrival and avoid light in the evening to help advance your circadian rhythm.

😴

Sleep Schedule

Gradually shift your sleep schedule toward Tokyo's timezone starting 2-3 days before departure. For this large time difference, consider splitting the adjustment before and after your flight.

⏱️

Expected Recovery

Your body will adjust at approximately 1.3 hours per day. The first 2-3 days will be the hardest.

Why This Plan Works

Direction Matters: Eastward travel is harder on your body because you're trying to fall asleep earlier than your body wants to. It typically requires more time to adjust.

Light is Key: Properly timed light exposure is the most powerful tool for resetting your circadian rhythm. Morning light advances your clock, while evening light delays it.

Recovery Timeline: With a 15-hour time difference, expect approximately 12 days to fully adjust to the new timezone if you follow the recommended light exposure and sleep schedule.
