Understanding Jet Lag

Jet lag occurs when your body's internal clock (circadian rhythm) is out of sync with the local time at your destination. Crossing 3+ time zones typically causes noticeable symptoms including fatigue, insomnia, difficulty concentrating, and digestive issues.

Recovery Tips

Before your trip: Gradually shift your sleep schedule 1-2 days before departure. If traveling east, go to bed earlier; if traveling west, stay up later.

During flight: Stay hydrated, avoid alcohol and caffeine, and try to sleep if it's nighttime at your destination. Use eye masks and earplugs to create darkness and quiet.

Upon arrival: Expose yourself to natural light at destination meal times. Eat meals at local times. Avoid napping during local daytime.
