Jet lag is your body clock stuck in the wrong time zone. You can't skip it entirely, but the right light, timing and sleep moves can cut days off the recovery — here's how.
Roughly a day per time zone crossed, so a 6-hour shift can take several days to fully clear. Good light timing and sleeping on the local clock can noticeably speed that up.
Flying east shortens your day and forces you to sleep earlier than your body wants, which is hard. Flying west lengthens your day, and staying up a bit later is much easier — so westward jet lag usually clears faster.
For many people a low dose taken about an hour before the target local bedtime helps shift the body clock, especially flying east. Effects vary, and it can interact with medications — check with a pharmacist or doctor first. This is general info, not medical advice.
