Key Highlights:

Dr. Kevin Lin’s background: A sleep surgeon with a passion for travel and optimizing rest.
Understanding jet lag: It’s a misalignment of your circadian rhythm due to time zone shifts.
East vs. West: Traveling east often causes worse jet lag because it shortens the body’s day.
Personalized reactions: Jet lag affects people differently—preparation is key.
Smart prep: Begin shifting your schedule a few days before travel.
Melatonin insights: Best taken 3–4 hours before target bedtime in small doses.
Meal timing: Adjust your eating schedule to match the destination’s schedule to help synchronize your internal clock.
Sunlight exposure: Morning light helps reset your body faster upon arrival.
Light therapy tools: Helpful for managing long-haul jet lag when natural light isn’t an option.
Napping strategy: Keep naps short (20–30 minutes) to avoid feeling groggy or experiencing sleep disruption.
Sleep trackers: Can help build awareness, but shouldn’t be the sole metric of sleep quality.
Tips for frequent travelers & athletes: Consistency, nutrition, and hydration are essential for high performance.
