Soften the time-zone landing
Specific timing rules for light, sleep, caffeine, melatonin, screens, naps, and the first local day.
Before You Fly
- For trips crossing several time zones, move bedtime, wake time, meals, and bright light 30 to 60 minutes toward destination time for 2 to 4 days.
- Do not start the trip sleep-deprived. A tired travel day feels like jet lag and makes the first night harder.
- Set your phone and saved clock to destination time before boarding so meals, caffeine, darkness, and sleep follow the place you are going.
Time Light And Darkness
- Eastbound trips usually need morning outdoor light and a dim evening. Westbound trips usually need afternoon or early-evening light.
- Use sunglasses, shade, or indoor time when bright light would pull your body clock the wrong way.
- In the last 90 minutes before target bedtime, dim overhead lights, stop work, and put bright screens away.
Use Melatonin Carefully
- If melatonin is safe for you, use a low immediate-release dose, usually 0.5 to 3 mg, 30 to 90 minutes before destination bedtime.
- Skip melatonin during the local day because mistimed doses can make you sleepy and slow adaptation.
- Avoid melatonin with alcohol or sedatives, and ask a clinician first if pregnant, taking warfarin, or managing seizures.
Caffeine, Naps, And Meals
- Use coffee or tea for local morning alertness, then stop by early afternoon so caffeine is not active at bedtime.
- If you must nap, set an alarm for 15 to 20 minutes and wake before midafternoon.
- Eat smaller meals on travel day, then put breakfast, dinner, and snacks on destination time after arrival.
Make Day One Gentle
- After landing, take a 20 to 30 minute outdoor walk when it matches your light plan.
- Keep arrival plans low-stakes: one simple meal, water, a shower, and only the unpacking needed for sleep.
- Make the hotel room cool, dark, and quiet. Use an eye mask or blackout curtains, then hold local bedtime even if sleep starts slowly.
