JET LAG MYTHS VS. CIRCADIAN SCIENCE
Misleading advice on conquering jet lag — often promoted by non-experts — not only fails to help travelers but can make jet lag symptoms worse and may even cause harm.
It’s time to replace the myths with real science.
Generic sleep advice, exercise, hydration, grounding, dietary supplements, special diets, or fasting won’t solve jet lag because they don’t "reset" your circadian clock to new time zones.
THE REAL JET LAG SCIENCE
// In your brain, a circadian clock helps manage the regular rhythm of your day.
// Jet lag is caused when your sleep/wake and light/dark cycles shift too quickly for your circadian clock to keep up.
// Light is the key time cue to “reset” your circadian clock, so the correct timing of light exposure and avoidance is the only way to adjust to new time zones quickly. If your timing is wrong, it will make your jet lag worse.
WHY WE MADE TIMESHIFTER
Getting the timing right is both complex and unintuitive. We created Timeshifter to make circadian science accessible and help you apply it to conquer jet lag.
Timeshifter helps you tackle both the underlying cause of jet lag – the disruption of your circadian clock – as well as reduce the disruptive symptoms, such as insomnia, sleepiness and digestive discomfort.

I’ve been travelling for work for over 20 years .. after a very very long trip in July (110 hours of travel in 14 days) I was exhausted for one entire week ... I decided to look for a better way to do this ... found this app .. waited for my next very long trip .. in a period of 17 days I had - Singapore, Japan, Australia,Singapore, Atlanta (USA) and back to Singapore (home).... I used this app to a tee on the singapore - Atlanta - Singapore portion .. ( supported by using sunglasses (when the advice was to go dark), and bright glasses when I needed bright light and there was no sun out (retimer glassses)... I had very little jet lag on the way over to the USA... and NONE on the way back to Singapore ... this is a first in travelling all my working life ..... brilliant, brilliant! If you travel beyond 3+ hours in time difference this app will really help ... highly recommended!!
Exceptional product!!

I have used Timeshifter twice now, and each time it’s proven immensely valuable. I’m getting old (over 50) and jetlag becomes a little tougher to manage each year. My first trip was to the USA from Singapore and I believe Timeshifter gave me back 4 or 5 hours every day as I was able to hit the office early, and have a productive day in the office, and then out to dinner at night without feeling like rubbish (I followed the app recommendations 90% of the time). Timeshifter gives me back quality time, instead of that groggy, tired jet laggy feeling, I was on peak performance. I highly recommend this app to anyone that travels.
Road warrior and the first time without jetlag

I have been traveling for work very frequently and regularly cross 16 hours time difference. As you can imagine this turns your entire life up side down. I started to use Timeshifter on my last trip and I’m truly amazed! I honestly do not have jetlag - event though traveling for close to 24 hours and crossing 16 time zones. It is important you follow the directions the app gives on on when to drink caffeine, find light and go to sleep - but It Works!!! I am no longer dreading long trips! Well done guys!
Outstanding Results

I’ve been a frequent international traveler for over a decade, including dozens of cross-Pacific flights. Even though I am experienced in managing jet lag, I was surprised at how much better the Timeshifter protocol worked for my last trip (from Las Vegas to Singapore). I experienced virtually no jet lag. It was far and away the easiest time zone transition I’ve ever had. Highly recommended!
