JET LAG MYTHS VS. CIRCADIAN SCIENCE
• Misleading advice on conquering jet lag – often promoted by non-experts or companies lacking real circadian science expertise – not only fails to help travelers but can make jet lag symptoms worse and may even cause harm.
• Jet lag CANNOT be fixed with generic sleep advice, exercise, hydration, dietary supplements, special diets, or fasting. None of these approaches will reset a traveler’s central circadian clock quickly to new time zones.
• Light is the key time cue to “reset” our circadian clocks, so the correct timing of light exposure and light avoidance, based on the traveler’s chronotype, normal sleep pattern and itinerary, is the only way to adjust to new time zones quickly. If the traveler’s timing is wrong, it will make their 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.

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 nearly 30 years of research experience. Dr. Lockley helps NASA astronauts and mission controllers, Formula 1 drivers, NBA players, and Olympic athletes perform at their best.
