What type of flights requires adjusting lighting for passenger comfort?

Adjusting lighting for passenger comfort is especially important on night flights. This consideration is primarily due to the natural circadian rhythm of the human body, which is influenced by light. In night flights, passengers are often trying to sleep or rest, so the cabin lighting is usually dimmed to create a more conducive environment for relaxation and to simulate nighttime conditions.

During these flights, the crew aims to minimize disturbances by reducing light exposure, which can help passengers feel more comfortable and restful during their journey. This contrasts with day flights, where brighter cabin lighting may be more suitable to keep passengers alert and active.
