JET LAG MYTHS VS. CIRCADIAN SCIENCE
Jet lag cannot be fixed with generic sleep advice, exercise, hydration, dietary supplements, special diets or fasting. None of these reset your circadian clock quickly to a new time zone.
Light is the key time cue that resets your circadian clock. Individually-timed light exposure and light avoidance - based on your chronotype, your normal sleep pattern and your itinerary - is the only way to adjust to a new time zone quickly. Get the timing wrong and jet lag gets worse.
Getting that timing right is complex and unintuitive, which is why generic advice fails. Timeshifter works as your jet lag calculator and planner, doing that timing for you.
WHY WE MADE TIMESHIFTER
We built Timeshifter to make circadian science accessible and help you apply it to reduce jet lag. It targets the underlying cause of jet lag - the disruption of your circadian clock - and reduces the symptoms that come with it, including insomnia, daytime sleepiness, fatigue and digestive discomfort.
Timeshifter was developed with Dr. Steven W. Lockley, a Harvard Medical School faculty member for over 20 years and former neuroscientist at Brigham and Women's Hospital. He is an international authority on circadian rhythms and sleep, with more than 30 years of clinical research experience in humans, and works with NASA astronauts and mission controllers, F1 teams, NBA players, national soccer teams and Olympic athletes.
Whether you are crossing one time zone or ten, on a long-haul flight or a quick turnaround, Timeshifter gives you a jet lag plan built for that trip.

I used to suffer greatly from jet lag. For my latest trip I used the timeshifter app and I managed to adhere to a fair share of their recommendations. This partly felt a bit odd (like wearing sunglasses on an airport, because it happens to be the time, when you are meant to avoid sunlight), but the result was very convincing as I had next to no jetlag both arriving at my destination and coming back home.
Was really helpful

Used the app for a short trip Europe-NYC. Gave my flight numbers and followed as good as I could the Timeshifter plan (you can even include intake of melatonin). Really helped me manage the journey. Had nearly no jet lag. Recommend. Thx (it could eventually be a useful feature for active people to include when you should-could exercise)
Super apps pour les longs courriers

D'habitude, quand je fais aux USA (depuis l'EU donc) j'ai toujours la gueule dans le paté une fois sur deux (à l'aller ou au retour, parfois aux deux, l'angoisse). Mais pas depuis que j'ai découvert cette app. Même suivre 50/75% des recommendations suffit à se resynchroniser beaucoup plus rapidement à la nouvelle timezone dans laquelle on se trouve. Et cela parceque ca ne consiste pas à quelques trucs lors du voyage, non. Timeshifter donne des recommendations 2 jours avant / 2 jours après le voyage pour faiciliter l'adaptation. Et ca marche de fou!
We release updates regularly, and we're always looking for ways to make the experience better.
