If you have ever traveled to countries where the time difference of that country and your home is huge, you’ve probably experienced a rather nasty side-effect known as jetlag. For those who haven’t experienced jetlag, it basically makes you tired at odd hours of the day and extremely awake and alert in the dead of the night.

This is because your body isn’t used to the time difference and the times you’re feeling sleepy would actually be the times that you should be asleep in your country. Now thanks to a group of mathematicians from the University of Michigan, they claim to have developed an app called Entrain that will supposedly do away with the feeling of jetlag.

The app claims to help users synchronize their “circadian rhythms with the outside hour” that will supposedly help to eliminate the effects of jetlag. This is accomplished by having the user adjust the light of their surroundings, such as light to dark, dark to light, according to what the app tells them to do.

According to the University of Michigan, “Start by entering your typical hours of light and darkness in your current time zone, then choose the time zone you’re traveling 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 specialized plan and predicts how long it will take you to adjust.”

It sounds like it could be helpful and it’s definitely an app we’ll want to try the next time we fly into other time zones. In the meantime if you’d like to learn more, check out the video above or head on over to Entrain’s website for the details.
