How to Avoid Jet Lag travel guide

Cross time zones and still arrive fresh — simple, proven ways to reset your body clock.

Quick facts: Flying · 5 min read · Updated June 2026. Practical, original travel advice for any trip.

Why it happens

Jet lag hits when you cross time zones faster than your body clock can adjust. The more zones you cross — and especially flying east — the harder it can be, but you can soften it a lot.

When you land

The rough rule

It takes roughly a day per time zone to fully adjust, but good light exposure and sleep habits speed it up. Most people feel normal within two or three days.

Frequently asked questions

What about before you fly?

Shift your sleep an hour or two toward your destination for a few days. Arrive rested rather than sleep-deprived. If you can, pick a flight that lands in the evening so you sleep soon after.

What about on the plane?

Set your watch to destination time and sleep accordingly. Drink plenty of water; go easy on alcohol and caffeine. Get up and move every couple of hours.

What about when you land?

Get outside in natural daylight — the single most powerful reset. Stay awake until a normal local bedtime; resist long naps. Eat meals on the local schedule. Keep day one light and flexible.
