Jet Lag from Los Angeles to Beijing

Beijing runs 15 hours ahead of Los Angeles — a eastbound shift over a roughly 13-hour flight. Expect about 15 days to feel close to normal in Beijing.

What to expect

Eastward shifts compress the day and fight the natural drift of the human circadian rhythm, so they tend to feel harder than westward shifts of the same magnitude.

Adjustment playbook

• Shift bedtime earlier by ~1 hour per day before departure.
• Reset your watch to Beijing time at boarding.
• On arrival, get bright morning light and avoid bright evening light.
• Caffeine in the morning only.
