Young children and jet lag: how to manage time zones

On board: anticipate the destination time zone early

If it will be night at the destination, creating a dark, quiet environment on board to promote the child's sleep helps their body adjust in advance, even if the sun is shining outside the window. Setting the clock to the arrival time zone as soon as you board makes it easier to follow this logic for the entire duration of the flight.

Natural light and melatonin upon arrival

Once at the destination, exposure to natural light in the early hours of the day is the most powerful synchronizer for children's circadian rhythm, because it helps block melatonin production at the wrong times. To organize light exposure in the days following arrival, it can be helpful to follow a practical time zone adjustment calendar.

Hydration, light meals, and night waking

Keeping the child well hydrated reduces jet lag irritability, while offering light snacks instead of heavy meals in the first days accommodates a metabolism still finding its new rhythm. If the child wakes in the middle of the local night, avoiding bright lights or stimulating games and maintaining a calm atmosphere promotes faster return to sleep.

Once you land, keep your children outdoors in full daylight for at least 20–30 minutes: it's the most effective signal to restart their circadian clock on the new time zone.
