About jetlite

More than 60% of all passengers on long-haul flights suffer from jetlag - with mostly extensive consequences. After a flight over several time zones, the sleep-wake cycle is clearly disturbed, hormone production and body temperature get out of step. Tiredness, dizziness, mood swings, gastro-intestinal problems or headaches are just a few common symtoms.

Jetlag can even have an impact on the economy as the performance and well-being of business travelers are affected.

Besides that, airlines constantly aim for differentiation and perfectly satisfied guests.

Our mission is to actively contribute to the reduction of jetlag, while increasing passenger comfort and helping airlines to distinguish from competition.

What we offer

jetlite offers a holistic and algorithm-based approach to increase the comfort of passengers over the whole passenger journey by mitigating jetlag through three key factors:

jetlite algorithm

Our algorithm provides chrono-biologically improved lighting for aircraft & airports. It adapts the cabin lighting considering specific parameters. 24 lighting scenarios can be set to fit with the day and night-time biorhythms of the passengers to ensure that they arrive well rested and with less jetlag. 

Customized nutrition concepts

Jetlite has developed customized nutrition concepts for airline catering and airport services to complement the cabin lighting in order to mitigate jetlag. The key is to provide the right nutrients at the right time to either evoke sleep or activation.

App-based  recommendation

We are developing a smartphone application that calculates the ideal bedtime, light and nutrition for a passenger – days ahead of a flight based on destination and personal sleeping rhythms.

Benefits for airline & passenger.

The Scientific Research Behind Jetlite

Mock-up cabin with test subjects and jetlite lighting concept.

Flight simulations with Osram, Airbus, Diehl and Fraunhofer Institute

The idea for jetlite first came up in the context of Founder Achim Leder's PhD dissertation at Bergische Universität Wuppertal. Osram, Airbus and Fraunhofer Institute for Building Physics were convinced by the research idea and agreed to become partners. The infrastructure for the comprehensive tests was provided by Diehl.

Comprehensive tests have been conducted where long-haul flights were simulated with subjects spending ten hours at a time, three times over, in a mock-up cabin. The test group was subject to lighting with a higher red level in the evening and higher blue level in the morning. The subjects then went through the same route with normal cabin lighting.

The results of the tests were clear. When exposed to normal cabin lighting, the subjects quickly experienced typical jetlag symptoms. After applying the jetlite lighting, though, they slept more quickly and deeply and were more wide awake at the simulated arrival. Building on this concept, the jetlite algorithm to calculate the optimal lighting program for various flight routes, has been developed.
