Arrival Strategy for Seattle

How to manage jetlag based on arrival time

Morning Arrival

Upon morning arrival, immediately engage with local time by getting natural sunlight and staying active. Avoid long naps and consume light, nutritious meals to help reset your circadian rhythm.

Afternoon Arrival

Afternoon arrivals should minimize caffeine and exposure to screens. Take a short 20-30 minute nap if necessary, but ensure it doesn't extend beyond that to prevent deeper sleep disruption.

Evening Arrival

For evening arrivals, limit heavy meals and alcohol. Create a dark, quiet sleep environment and aim to align with local nighttime as quickly as possible to minimize jetlag impact.
