Frequently asked questions

How can I adapt quickly to a new time zone according to the latest in sleep and circadian neuroscience?
Surprising to many, light — not sleep, exercise, food, or caffeine — is the most important time cue for resetting your circadian clock, and the only way to quickly reset the clock and address jet lag. The precise timing of when to see light and when to avoid light is the difference between a successful trip or a miserable one. Timing is everything when it comes to jet lag and doing things at the wrong time can shift your rhythms in the wrong direction, making your jet lag worse.

What science proves that Timeshifter works?
Timeshifter uniquely combines the only elements that have been shown to significantly reset the circadian clock (light exposure and melatonin), or alleviate the symptoms (melatonin, caffeine, naps). As new research emerges, our world-renowned scientists are either authors of it, or have the unsurpassed professional expertise to assess and incorporate it if credible and impactful.

I have heard of some other ways to conquer jet lag — could they work as well or better?
There are many persistent misconceptions about how to cure jet lag: ”Get as much sleep as possible on the plane”, “stay hydrated and eat only certain foods”, “use sleep medication”, “get onto local time as soon as possible”, “get out in the sun if arriving during the day”, “use caffeine to power through”, etc. Unfortunately, no generic solution can help you tackle the underlying cause of jet lag, and might even be counterproductive, making your jet lag worse.
