Estimate Jet Lag Recovery

Formula

Eastward: Recovery days = zones / 1.5. Westward: Recovery days = zones / 2.

Frequently Asked Questions

Why is eastward travel harder?
Eastward travel requires advancing your body clock (going to sleep earlier), which is harder for most people than delaying it. Recovery rate is approximately 1 day per 1.5 zones eastward vs. 1 day per 2 zones westward.
How can I minimize jet lag?
Gradually shift your sleep schedule before travel, stay hydrated, get sunlight at appropriate times at your destination, avoid alcohol and caffeine on the flight, and consider melatonin supplements.
