Re-Timer combats jetlag

A device with special technology created by Flinders University of Adelaide that will reset the body’s internal clock

It looks like something for a game console, but the Australian device is worn like sunglasses and emits soft green light that contributes to combatting jetlag. And there's more. It would also help shift workers by reducing tiredness and the difficulty of adapting to rhythms of sleep that are always changing, or even convince kids to go to bed early by advancing or delaying their sleep patterns.


Professor Leon Lack, the psychologist who invented the device, explained that the Re-Timer light stimulates the part of the brain regulating circadian rhythms. The device is the result of 25 years of sleep research at Flinders University. "The body's clocks or circadian rhythms affect our sleep patterns, alertness, performance levels and metabolism," Lack said.


How does it work? The professor explained that the photoreceptors in our eyes detect sunlight and tell our brain to be awake and alert, thereby setting our sleep patterns, which vary regularly in a 24 hour cycle. However, this process is frequently disturbed by traveling in different time zones, irregular work schedules, or by lack of sunlight during the winter months. The problem can be solved by making our eyes see a different type of light: "Our research on a vast scale has demonstrated that green light is one of the most effective wavelengths for advancing or delaying the body clock and currently (Re-Timer) is the only wearable device with green light."


It is important not to overdo it, as Professor Lack confirmed. The device should be worn for 50 minutes a day for three days, after waking up in the morning to advance the body clock, or before going to sleep if you want to delay the body clock and wake up later.
