Jet lag - how many days does it last?

The duration depends on direction, time zones, and your rhythm. The effect can feel uneven for several days.

  • A rough rule of one day per time zone is only a loose frame.
  • Eastward travel often feels harder.
  • The background can stay uneven for a few days.
