Time Zones and Tired Bodies: Adjusting Gently

Adjust gently, in steps, using light, meals and the familiar bedtime sequence as your levers. On arrival, move toward local time rather than defending home time: get outside into daylight, eat at local mealtimes even if the amounts are small, and run the usual bedtime order at the new local bedtime even if your child is not yet tired when it starts. Expect the shift to take a few days, plan nothing demanding early in the trip, and allow a daytime rest without letting it swallow the whole afternoon. The same gentleness applies on the way home, with the re-entry approach in coming home: the re-entry day. Bodies adjust at their own pace; the family's job is to supply steady signals - light, food, sequence, darkness at night - and low demands while the adjustment happens.

A child's sense of day and night is set less by clocks than by signals: bright light in the morning, food at regular times, activity in the day, dim light and quiet sequences in the evening. Travel scrambles those signals all at once, which is why willpower - just go to sleep - achieves so little at three in the morning in a new place. Working with the signals instead is slower but real: daylight walks pull the day into shape, meals eaten at local times give the body appointments to organise around, and the bedtime sequence tells the body what is coming even when the clock says something odd. The sleep sources below describe how much rest children need at each age; on adjustment days, aim to protect the total amount across the day rather than the exact hours, and let the hours migrate toward local time over several days.

These are the moves families find most useful, in rough order:

• On the journey, set watches and talk to local time from the moment you board or set off.
• On arrival, get outside in daylight as soon as you can, and keep rooms bright in the morning.
• Eat at local mealtimes; small and familiar beats large and adventurous while bodies adjust.
• Run the home bedtime sequence at the local bedtime from the first night.
• Allow a short daytime rest early in the trip, kept brief and early in the afternoon.
• Book nothing early, loud or unmissable for the first two days.

The sequence you are protecting is the same one described in keeping some routines on holiday - which is why anchors earn their place twice over on long trips.

Some nights your child will simply be awake, and some afternoons they will be leaden. Keep night wakefulness boring and dim: quiet activities, low light, no big meals, no screens bright in the face, and the message that rest in bed still counts. Wake a child who is sleeping the day away gently and in stages - curtains open, household noise returning, a drink and a snack offered - rather than with a sudden announcement. Avoid turning the adjustment into a battle of wills; a body clock cannot be argued with, only guided. If the return home is the harder direction for your family, as it is for many, build the adjustment days into the home end of the trip instead, and tell school in advance that the first mornings may be slow if that conversation is appropriate.

Illustration only: after a long flight east, one family treated the first three days as adjustment days on purpose. Mornings began with a walk to buy breakfast, eaten outside where possible. Days held one small outing each, afternoons allowed a short rest, and the bedtime sequence ran at the new time from night one, starting drowsily and late the first evening and settling earlier each night. By the fourth day the child was waking near local breakfast time. The family counted the slow days as part of the holiday rather than a loss of it, which changed how the whole trip felt.

Light in the morning, meals at local times, the same bedtime sequence, dark and boring nights, and a trip plan that forgives the first days: that is the whole method. It will not make a body clock jump, but it stops the family fighting the clock while it moves - and a child who is allowed to adjust gently usually arrives, a few days in, ready to enjoy the place you travelled so far to see.
