Science-Backed Methods to Adjust Quickly

Jet lag can be one of the biggest downsides of long-distance travel. It occurs when your body’s internal clock, or circadian rhythm, is out of sync with the time zone you’ve traveled to. Symptoms like fatigue, insomnia, headaches, and digestive issues can make adjusting difficult. However, with the right strategies, you can minimize or even avoid jet lag altogether.

Understanding Jet Lag

Jet lag happens because your body’s natural sleep-wake cycle is still aligned with your departure location, making it difficult to adjust to a new time zone. The severity of jet lag depends on factors like the number of time zones crossed, direction of travel, age, and individual sleep habits.

Science-Backed Methods to Avoid Jet Lag

1. Adjust Your Schedule Before You Fly

• For eastward travel (harder to adjust to): Go to bed earlier in the days leading up to your trip.
• For westward travel (easier to adjust to): Go to bed later before your flight.
• Shift your meal and wake-up times slightly to align with your destination’s time zone.

2. Get Sunlight at the Right Times

Exposure to natural light helps reset your internal clock.

• If traveling east: Get morning sunlight at your destination to advance your internal clock.
• If traveling west: Seek afternoon sunlight to delay your internal clock.
• Avoid bright light at night to prevent further disruption to your sleep cycle.

3. Stay Hydrated and Avoid Alcohol or Caffeine

• Dehydration worsens jet lag symptoms, so drink plenty of water before, during, and after your flight.
• Avoid alcohol and caffeine, as they interfere with sleep and can make adjusting harder.

4. Use Strategic Napping

• If you need to nap, keep it short (20-30 minutes) and take it at the right time based on your new schedule.
• Avoid long naps, which can make adjusting more difficult.

5. Consider Melatonin Supplements

• Melatonin is a hormone that helps regulate sleep. Taking a small dose (0.5–3 mg) an hour before bedtime in your new time zone may help you adjust faster.
• Use melatonin for a few days upon arrival but avoid relying on it long-term.

6. Adjust Your Watch and Mindset Immediately

• Set your watch (or phone) to your destination’s time as soon as you board the plane.
• Start thinking in your new time zone to mentally prepare for the adjustment.

7. Stay Awake Until Local Bedtime

• No matter how tired you are, resist the urge to sleep at the wrong times.
• Staying awake until at least 9–10 PM local time will help reset your circadian rhythm faster.

While jet lag can’t always be avoided completely, following these science-backed strategies can significantly reduce its effects. The key is gradual adjustment, proper light exposure, hydration, and maintaining a disciplined sleep schedule.

By preparing ahead and sticking to these methods, you’ll be able to adjust quickly and make the most of your travels—without losing days to exhaustion.
