Jet-lag and dried-out mucous membranes are just some of the uncomfortable side-effects of long-haul air travel. Researchers from the Fraunhofer Institute are working to counter these problems and conduct research in a one-of-a-kind laboratory: a pressure cabin that contains the front section of a A310.
It allows them to simulate realistic flight conditions. One of their ideas is to introduce a lighting system on board planes - because light affects human body clocks. Red light makes passengers sleepy, while blue light energizes them.
