How to Beat Jet Lag
Jet lag happens when your internal body clock is out of sync with the time at your destination. The bigger the time difference, the worse it hits. You can't eliminate it entirely, but with the right light, sleep, and timing strategy you can cut its severity dramatically.
Why Jet Lag Happens
Your body runs on a roughly 24-hour internal clock (circadian rhythm) tuned by light, meals, and routine.
Crossing time zones faster than your clock can adjust leaves you sleepy during the day and wide awake at night.
It generally takes about one day per time zone to fully adjust if you do nothing.
Eastward travel (losing time) is usually harder than westward travel (gaining time), because advancing your clock is tougher than delaying it.
Before You Fly
A few days before departure, shift your sleep schedule an hour earlier (flying east) or later (flying west) to pre-adapt.
Arrive at the airport rested — starting a long-haul flight already exhausted makes everything worse.
Set your watch and phone to the destination time zone as you board, and start thinking in destination time.
Avoid heavy nights out or alcohol in the days before a big trip.
On the Plane
Sleep according to your destination's night, not your origin's. If it'll be daytime when you land, try to stay awake near the end of the flight.
Hydrate constantly — cabin air is extremely dry, and dehydration amplifies fatigue.
Avoid or minimize alcohol and caffeine, which disrupt the sleep you're trying to control.
Use an eye mask, earplugs, and a neck pillow to actually sleep when it's destination night.
Get up and move every couple of hours to improve circulation.
Use Light Strategically
Light is the most powerful tool for resetting your clock. Bright light in the morning shifts you earlier; evening light shifts you later.
Flying east: seek bright morning light at your destination and avoid bright light late in the day.
Flying west: get light in the late afternoon and early evening to push your clock later.
Spend time outdoors on arrival — natural daylight works far better than indoor lighting.
After You Land
Adopt the local schedule immediately — eat meals and sleep at local times even if your body protests.
Resist the urge to nap longer than 20–30 minutes; long daytime naps prolong jet lag.
Stay active and outdoors during the day to anchor your new rhythm.
Caffeine in the morning can help you push through; avoid it within six hours of bedtime.
Does Melatonin Help?
Melatonin is a hormone that signals your body it's time to sleep. A low dose (0.5–3 mg) taken at destination bedtime can help reset your clock, especially flying east.
Timing matters more than dose — take it at the destination's bedtime, not your origin's.
It's not a sleeping pill; it nudges your rhythm rather than knocking you out.
Check local regulations and talk to a pharmacist or doctor if you're unsure, especially if you take other medications.
