Once you have added your flights in the app, your jet lag plans will be listed on the advice page as circles with a destination and a date. If you do not see your jet lag plans, tap the middle icon with three stripes to view them.

To effectively tackle jet lag, it is crucial to begin timeshifting before your departure.

If you start timeshifting after your departure, we lack information about your light exposure and sleep patterns since you left. These factors significantly influence your circadian clock, potentially shifting it towards or away from your destination time zone.

Starting your jet lag plan before your departure ensures that we have the correct information to help you adjust effectively to your new time zone.

While it's technically possible to start a plan earlier, it would require that you take actions that are often impractical and unlikely to fit into your normal schedule.

Therefore, we recommend following the plan as provided to ensure the best results.
