From Wikipedia: “Jet lag, medically referred to as desynchronosis, is a physiological condition which results from alterations to the body’s circadian rhythms resulting from rapid long-distance transmeridian (east–west or west–east) travel on high-speed aircraft. It was previouslyclassified as one of the circadian rhythm sleep disorders.”
Fortunately, as it has been the case with a plethora of situations, there is a new app for this condition: Entrain app is designed especially to help people who travel by plane to adjust to new time zones. You might ask how does this work? It’s quite simple. The app lets you know when to manipulate the exposure to light in order to adjust to new time zones faster, by cheating the circadian clock. This is because light is very important and it influences people’s circadian clock and the way this regulates our bodily functions, such as sleeping.
The circadian rhythm is our master biological clock which actually dictates when to go to sleep and when to be more alert. When we travel across time zones our body clock has to reset itself – its strongest regulator is the light exposure.
The Entrain app designs lighting schedules for its users, based on their own itinerary. All of these schedules follow one basic rule: we must be exposed to the brightest light at one point in the day and to darkness at another point.
Depending on where your destination is, the app may suggest that you expose yourself to a bright outdoor light, late at night. Same goes for the darkness scenario: if you need to go outside into bright daylight when your schedule knows that you should do some night time activity like sleeping, you can wear pink tinted glasses.
Entrain app – how does it work?
When launching the Entrain app it will ask you to type in the time you usually wake up and the approximate hour you go to sleep at night. The app then asks you to select a light exposure that is typical for you: low indoor, bright outdoor, low outdoor and bright outdoor. Based on these criteria, the app will model your circadian clock. We can’t wait to test it and tell you if it actually works.
You can download the Entrain app for from the iTunes store.
