This might work on short flights, but short flights generally don't give us serious jet lag.
On long flights (e.g. London to San Francisco), I don't think any amount of fancy lighting will be able to compensate for the fact that your day has suddenly become 32 hours long and you've been awake for 24 of them.
Do you suddenly feel refreshed if you see another sunrise (whether real or simulated) after having been awake for 24 hours straight? Not me... at least not since my early 20s.
- mikeash 11y agoJet lag isn't about feeling tired after being awake for 24 hours straight, and defeating it wouldn't mean that you arrive at your destination wide awake despite having had no sleep for a full day. Jet lag is the persistent desync between your body's internal clock and the sun's actual position, which lasts for several days after a rapid trip across many time zones. It's not about getting to your destination feeling refreshed, but waking up the next morning without feeling like it's time for bed.
