New Delhi: Do you suffer from jet lag? Researchers have come up with a mobile app which offers ways to overcome it by snapping internal clocks of travellers to new time zones.
A Jet lag happens when one is travelling through different time zones and working unsociable hours, which often makes people either tired or unable to sleep. Frequent head spinning, insomnia and fatigue are some of the symptoms of jet lag.
The new iPhone app, called `Entrain`, is believed to be the first to take a numbers-based approach to “entrainment” - the scientific term for synchronising circadian rhythms with the outside hour.
Entrain is built around the premise that light, particularly from the sun and in wavelengths that appear to our eyes as the colour blue, is the strongest signal to regulate circadian rhythms.
Once you download the app, start by entering your typical hours of light and darkness in your current time zone.
Then choose the time zone you are travelling to and when, as well as the brightest light you expect to spend the most time in during your trip (indoor or outdoor).
The app offers a specialised plan and predicts how long it would you take to adjust.
The shortcuts `Entrain` offers are custom schedules of light and darkness depending on the itinerary.
