'Sun specs' bring hope over jet lag

Many holidaymakers suffer jet lag after a long flight

Jet lag is one of the most frequent annoyances for long-haul travellers, but a new invention could mean holidaymakers no longer have to struggle to get to sleep as a result of travelling.

Australian sleep scientists have created a pair of specialised 'sunglasses', which have been designed to control sleep patterns by mimicking natural sunlight.

The researchers, from Adelaide's Flinders University, reported the specs release a relaxing green light, which helps the wearer adjust to different time zones in easy stages. It helps the brain adapt by transmitting messages to help the wearer become aware they are in a different place.

Also, it is sometimes easier for people suffering from travel-related insomnia to get to sleep once they have checked documents such as travel insurance and passports are in order.

Prof Leon Lack, chief inventor on the project, said: "The light from Re-Timer stimulates the part of the brain responsible for regulating the 24-hour body clock. Using a light device allows you to transition your body clock to a new time zone in small steps."

This removes the feeling of disorientation people often complain of after long-haul flights and reduces the severity of jet lag, he added.
