Finnair has recently announced they are to trial a new technology that is expected to cure jetlag for travelers on longhaul flights.  Passengers will be given headsets that will send light into the brain via the ear canal.  The method has been studied, tested, and observed by reputable scientists who believe the concept has great potential.  Studies have shown that exposure to bright light at the right time (early in the day when traveling east and late in the afternoon when traveling west) helps with the adaption of changing timezones and lack of sleep.  

Fingers crossed for all those travelers out there that it works!
