How do you get rid of jet lag fast?

The fastest ways to recover from jet lag: (1) Get morning sunlight at your destination immediately — 30 minutes outdoors in morning light is the strongest circadian reset signal. (2) Stay on local time for meals and sleep from the moment you arrive. (3) Use melatonin (0.5–3mg) timed to your destination's bedtime, not your home time. (4) Avoid long naps — cap at 20 minutes. (5) Book a window seat and bring an eye mask/noise-cancelling headphones for better in-flight sleep.

How to Beat Jet Lag on Long-Haul Flights (2026)

Jet lag is caused by your circadian rhythm being misaligned with the local time at your destination. Recovery time averages 1 day per time zone crossed — but you can shorten it significantly.

Before You Fly

Shift your sleep schedule 2–3 days early. Traveling east to Europe? Start going to bed 1–2 hours earlier a few days before departure. Heading west to Asia from the US? Stay up later.
Book the right seat for sleeping. Window seats let you lean against the wall without being disturbed. Exit rows have more legroom to stretch. Business Class lie-flat beds make overnight flights dramatically more restful.
Avoid alcohol the day before a long flight. Alcohol disrupts sleep architecture and dehydrates you — the opposite of what you want before 10+ hours at altitude.

During the Flight

Set your watch to destination time immediately. Eat and sleep according to destination local time on the plane, not your home time zone.
Use melatonin strategically. Melatonin is most effective when timed precisely: take 0.5–3mg (lower doses are often more effective) at your destination's bedtime. It signals darkness, not sedation — timing matters more than dose.
Stay hydrated. Cabin humidity is 10–20%, far drier than ground air. Drink water every hour; avoid alcohol and excess caffeine mid-flight.
Use an eye mask and earplugs or noise-cancelling headphones. Blocking light and noise significantly improves in-flight sleep quality even in Economy Class.

At Your Destination

Get morning light exposure. Sunlight is the strongest circadian reset signal. Go outside in the morning at your destination even if tired — 30 minutes of natural light accelerates adaptation.
Don't nap more than 20 minutes. A short power nap is fine; longer naps entrench your old sleep schedule and slow recovery.
Stay active. Light exercise at your destination — walking, light jogging — helps reset your body clock faster than sitting indoors.
Eat meals on local time from the moment you arrive. Your digestive system is a secondary circadian clock; aligning meal times accelerates full adjustment.
