My most reliable sleep hack for cross-country travel is strategic light exposure. When flying west, I wear blue-light blocking glasses on the plane and immediately get bright natural sunlight upon arrival to reset my circadian rhythm. Before flights, I prioritize hydration and avoid alcohol, then upon landing, I take a 20-minute walk outdoors regardless of how tired I feel. Since implementing this routine, my recovery metrics show I'm able to achieve deep sleep on my first night away, which has dramatically improved my morning energy and mental clarity for early meetings. This small investment in my travel routine pays dividends in my performance.
