Airplane Cabin Light Hygiene
Airplane cabin light hygiene aligns window, screen, and reading light with destination time—shade down for biological night, bright cues only when advancing alertness helps.
Airplane cabin light hygiene manages when you use the reading light, seat screen, and window shade to match your target timezone—not the meal service schedule. Dim or close the shade when destination is in biological night; open it when you need alerting morning cues if seat position allows.
Eye mask and headphones signal sleep mode to neighbors.
Common questions
-
Should you keep the window open all flight?
Only when destination local time is your planned wake or light-advance window. Otherwise shade down, eye mask on, and minimize seat-back screen brightness during biological night.
