Jet Lag from London to Singapore

Singapore runs 7 hours ahead of London — a eastbound shift over a roughly 13-hour flight. Expect about 7 days to feel close to normal in Singapore.

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 Singapore time at boarding.
• On arrival, get bright morning light and avoid bright evening light.
• Caffeine in the morning only.
