Can this revolutionary headset cure jet lag?
Many new-fangled cures for jet lag have been tried and tested, including a 'jet lag watch' and an acupressure kit, chugging down melatonin pills and using various sprays.
The jury's still out as to whether any of these really work, but Finnair has now unveiled a revolutionary new headset that may actually just work. It will be launched at the end of March.
The airline issued a statement revealing how the Valkee headset works. It explained: "The bright light headset simulates the effects of daylight by channelling bright light through the ear canal to very close proximity of the tissue in need of treatment, in the brain."
Valkee's website says that the headset helps to treat "circadian rhythm disorders", which is essentially what jet lag is.
The problem is mainly caused by the brain's inability to cope with the change in time zone while travelling on long distance flights. Symptoms can include headaches, irregular sleep patterns, mood swings and stomach trouble.
Light therapy has long been considered a help in overcoming general sleep problems, and, according to a report in the Daily Mail, Lawrence Epstein, Harvard's sleep physician, says bright sunlight or blue light can quicken adaptation.
Finnair will begin the trial in its business class section on flights between Helsinki and Shanghai - the journey is just under 10 hours. If a success, it will be rolled out widely. Do you have any cures for jet lag you'd like to share with us?
