It is well known that lighting plays a major role in maintaining the body clock. So onboard cabin lighting can help passengers in preventing jet lag. That is why airplanes are beginning to incorporate cabin lighting systems. The new Boeing 787 Dreamliner, which has just finished flight testing (Aug 2011) and will soon be used by airlines, has incorporated an LED system simulates daylight and a nighttime sky.
It is quite surprising it has taken this long for everyone else to jump onto cabin light therapy to help passengers, when Emirates Airlines has had this sort of airplane lighting since 2004 (read more about it here: Emirates: The Pioneers of Using Cabin Airplane Lights to Avoid Jet Lag).
LED lights allow for very slow fades, which simulates a more realistic sunrise and sunset onboard a plane. This slow fade allows passengers to fall asleep and wake up more naturally while on a flight – preventing jet lag. The lights are programmed to match the time of the destination, so when passengers arrive their body clocks will be more in sync and less tired.

Lighting is the main factor in battling jetlag, but there are a few other areas in which Boeing has redesigned to help passengers feel more refreshed when arriving at their destination.
Other ways of how to prevent jet lag and feel more relaxed onboard:
- Cleaner air with better air filtration system
- Higher levels of humidity
- The pressure within the 787 plane is 6,000 feet instead of 8,000 which gives people onboard 10% more oxygen
