Make jet lag history with highly personalized jet lag plans designed to reset your circadian clock effectively and quickly.

Jet lag is a common issue faced by travelers crossing multiple time zones, causing insomnia, fatigue, digestive discomfort, and reduced productivity. Despite widespread advice from various sources, many solutions often fail or worsen the condition because they do not address the root cause: your circadian rhythm disruption.

Understanding the science behind jet lag is crucial. Your brain contains a circadian clock that regulates your daily rhythms for sleep, wakefulness, and alertness. Jet lag occurs when your sleep/wake cycle and light exposure shift abruptly, leaving your circadian clock out of sync with the new time zone. The key to overcoming jet lag is resetting your circadian clock precisely through the correct timing of light exposure and avoidance.

Generic recommendations such as hydration, exercise, special diets, or supplements do not reset this clock and thus provide at best temporary relief. Timeshifter is built on proven circadian science, offering personalized jet lag plans that adapt to your individual profile, trip details, and preferences.

Pre-travel and post-arrival plans: Start adjusting your body clock before you fly and continue after landing to minimize jet lag symptoms.
