How to Beat Jet Lag Before Your Flight
35.) Ease Into It
Gradually prepare your body for the time zone changes ahead by slightly changing your routine a few days before your flight.
To simulate your new schedule beforehand, move your bedtime half-an-hour earlier for several days if you’re traveling east or move it later if you’re traveling west.
As you can imagine, this tip works best if you can adjust your other typical routines, like your mealtimes and work hours, so that they get as close as possible to those at your travel destination.
