After a long flight crossing several time zones, the body often falls into a kind of limbo: sleepy in broad daylight, wide awake at midnight, the mind foggy and hard to focus.
This is jet lag, when our internal biological clock hasn’t yet caught up with the time in the new place. Fortunately, there are many ways to help the body adapt faster.
Why the Body Gets Out of Rhythm
Our body runs on a biological clock that governs sleep, alertness, and many other functions, relying heavily on light. When you move quickly across time zones, this clock keeps running on the old time.
It takes some time for it to readjust, usually about one day for each hour of time difference. Understanding this helps you be patient and know how to support the process.
Adjust Before You Fly
A few days before the trip, you can gradually shift your sleep and meal times toward the time zone of your destination. Just going a little earlier or later each day gives your body a running start.
As soon as you board the plane, set your watch to the destination time and start thinking in that time. This helps your mind prepare for the new rhythm ahead.
Use Light and Sleep Wisely
Light is the most powerful tool for adjusting your biological clock. When you arrive, go outside and soak up the daylight; this helps your body recognize that it’s daytime and stay alert.
Try to sleep and wake on local time from the very first day, even if it’s hard at first. If you’re too tired and need a nap, keep it short, and avoid long daytime sleep that further disrupts your rhythm.
Eat and Move Sensibly
Drinking enough water during and after the flight helps reduce fatigue, because the air on a plane is very dry. Limit coffee and alcohol close to bedtime, as they disrupt sleep and make it harder to adapt.
Eating on the destination’s schedule helps signal the new rhythm to your body. A little light activity such as walking also helps you stay more alert and sleep better at night.
Jet lag is an unavoidable part of long journeys, but it doesn’t have to ruin those precious first days. With a few small adjustments to light, sleep, and food, you can soon fall in step with the new place and enjoy your trip to the fullest.
