How to Beat Jet Lag in Less Than 24 Hours (2025 Guide)
Travel Doesn’t Have to Wipe You Out
You’ve landed in Tokyo after flying from New York. It’s 9 AM, but your body thinks it’s bedtime. You’re foggy, cranky, and wide awake when you should be sleeping.
Sound familiar?
You’re dealing with jet laga common traveler’s nightmare. But here’s the good news: You can beat jet lag in less than 24 hours, and in this guide, we’ll show you how. Backed by science, personal hacks, and expert tips, these strategies can help you land on your feet (not your face) after long-haul flights.
What Is Jet Lag?
Jet lag is a temporary circadian rhythm disorder. When you travel across time zones quickly, your body clock doesn’t catch up. This results in:
-
Daytime drowsiness
-
Mental fog and irritability
-
Appetite loss or cravings at odd hours
-
Insomnia or fragmented sleep
“Jet lag isn’t just about sleep—it affects hormone levels, digestion, mood, and mental clarity,” says Dr. Charles Czeisler, a sleep medicine expert at Harvard.
How Many Time Zones Is Too Many?
| Time Zones Crossed | Jet Lag Severity | Recovery Time Without Help |
|---|---|---|
| 1–2 | Mild | 1–2 days |
| 3–5 | Moderate | 3–5 days |
| 6+ | Severe | Up to 1 week |
But don’t worry. With the right approach, you can shorten recovery to under 24 hours.
How to Beat Jet Lag in Less Than 24 Hours: Step-by-Step
1. Start Before You Fly
Adjust Your Sleep Schedule
3–5 days before your trip, gradually shift your sleep and wake time by 30–60 minutes toward your destination time zone.
Example: Flying east from LA to Paris (9-hour time jump)? Start sleeping and waking earlier.
Maximize Light Exposure
Get natural sunlight in the morning if you’re flying east. Use evening light if flying west. Light helps reset your internal clock.
2. During Your Flight
Stay Hydrated (But Avoid Alcohol)
Dehydration worsens fatigue and sleep quality. Drink at least 8 oz of water every hour. Avoid caffeine after takeoff and skip that free wine.
Sleep Strategically
Use a neck pillow, earplugs, and a sleep mask. If it’s nighttime at your destination, sleep on the plane. Use melatonin or mild natural supplements like valerian root only if needed.
Move Every Hour
Walk the aisle, stretch your calves, or do seated yoga. This improves blood circulation and reduces swelling and stiffness.
3. After Arrival: The First 24 Hours
Get Natural Sunlight—Immediately
Sunlight is the most powerful jet lag remedy. Spend time outdoors as soon as possible. If it’s still morning, take a walk. If it’s evening, limit exposure to screens and artificial light.
Eat at Local Meal Times
Even if you’re not hungry, have light meals at the new time zone. This helps regulate your digestive clock.
Light Exercise
Go for a walk, do light stretching, or swim. Avoid intense cardio, which could spike cortisol and interfere with sleep later.
Take Melatonin (Only if Needed)
If you’re adjusting to a night schedule, melatonin (0.5 to 3mg) 30–60 minutes before bedtime can help shift your sleep cycle. Avoid long-term use.

Personal Story: “I Recovered in Just 18 Hours”
Shared by: Mariana Lopes, full-time remote worker and digital nomad
“I used to dread my trans-Atlantic trips. But last year, I landed in Lisbon from Chicago, and used a combo of melatonin, light exposure, and meal syncing. I also walked for 40 minutes in the sun right after checking in. That night, I slept like a baby and woke up fresh. No grogginess. No weird hunger pangs. It really works.”
