Travel Circadian Light Plan
A travel circadian light plan times bright and dim exposure to destination clocks—outdoor morning light and deliberate evening dim beat random cabin brightness.
A travel circadian light plan schedules bright and dim light relative to destination time—not home time—across flights, layovers, and hotel rooms. Pack a small 10,000-lux lamp or plan outdoor walks at destination morning; wear sunglasses when you must avoid advancing or delaying phase.
Cabin LEDs alone rarely substitute for outdoor brightness.
Common questions
-
Do airplane windows provide enough circadian light?
Window light helps when you sit on the sunny side at the right local time—but brightness and timing are inconsistent. Plan destination outdoor walks or a travel lamp for reliable cues.
