Anyone who’s slept through the first day or so of their holiday, or arrived back from overseas only to toss and turn all night before falling asleep the next day, knows how inconvenient jet lag is.
Thankfully there’s now a free solution to this sleep-interfering problem. Created by The University of Michigan, Entrain is a free travel app that simulates your circadian clock on your phone and makes optimal lighting recommendations based on maths.
Designed to help you adjust as fast as possible to your new time zones and schedules, the recommendations, telling you to seek either light or dark, are based on research from the journal PLoS Computional Biology.
With the potential to save you from missing out on parts of your trip, not to mention falling asleep upright, it’s definitely worth testing out.
You can learn how to use Entrain at The University of Michigan website.
RRP: Free – iTunes App Store
