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 SCIENCE BEHIND REDUCING JET LAG

// 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.
