Symptoms may be more pronounced as more time zones are crossed. Most people find that jet lag is worse when traveling east than it is when traveling west.
Jet lag is a type of fatigue caused by travelling across different time zones. The body needs anywhere from a few days to a few weeks to acclimatise to the new time zone – approximately one day for each hour of time zone changes.
According to Massimino, regulating light exposure is critical to resetting your circadian rhythms and stopping jet lag in its tracks. “It's a timing issue to reset your circadian clock. So, based on the day-night cycle, when to see light and when to see dark allows you to shift more expeditiously,” he shared.
Most people find that jet lag is worse when traveling east than it is when traveling west. View Source . Jet lag differs based on the direction of travel because it's generally easier to delay your internal clock than advance it. Jet lag does not occur on north-south flights that do not cross multiple time zones.

One of the best ways to minimize jet lag is to try and sleep during the flight. Using earplugs, eye masks, or noise-cancellation headphones helps to block out light and noise.
Common ways pilots avoid jetlag is staying hydrated, good rest, avoiding caffeine and alcohol, exercising, or sleeping on the airplane. For long-haul flights airlines use multiple pilots for the flight to allow each pilot to get some rest. The more time zones that are crossed, the worse the jet lag.
Adjustment to a new time zone is harder when traveling east than traveling west. This is because you “lose” time and you end up trying to fall asleep when your body is actually waking up.
To calculate the amount of days it takes to recover from jet lag, the International Civil Aviation Organisation (ICAO) developed the following formula d = u 2 + ( z - 3 ) + v + a 10 u is the number of flight hours of the trip, and is the amount of timezones passed.
According to experts, not eating while you fly can actually help to reduce jet lag. (And that's not the only thing your flight attendant won't tell you.) Turns out, traveling on a plane can do a lot of bad things to your body—including shutting your digestive system down once you reach a high altitude.
