That’s right, there’s now a smartphone app that helps you adjust to changing time zones. After all, nobody wants to yawn their way through an international meeting because they were bright eyed and bushy tailed at 3:00 am. The app informs you when you should be in periods of darkness or light, and gradually changes those periods as you adapt to the new time zone. It uses periods of bright light to reset your circadian rhythm, i.e. make your body think that it’s day.
It’s true that by default, we use light as a trigger to feel awake and darkness as a trigger for feeling sleepy. But that’s not the only way.
As a business traveler, I am often going on very little sleep. The issue is not feeling tired. The issue is being able to make use of opportunities to rest, like when I’m sitting in an airplane seat. It’s about developing the internal ability to fall asleep rather than having to rely on external triggers, such as light and darkness.
You can learn how to fall asleep and get back to sleep. That’s what Travel Whisperers is all about. Learn how by downloading our free full length recording.
