Is jet lag worse going forward or back? Your circadian rhythm (body clock) is less confused if you travel westward. This is because travelling west 'prolongs' the body clock's experience of its normal day-night cycle (the normal tendency of the body clock in most of us is slightly longer than 24 hours).

One study claims it only takes two-thirds of a day per zone, or about six days to adjust to a nine-hour time difference (west to east). For westward flights it is somewhat easier to adjust to the time-zone shift, only requiring about half a day per time zone.
Scientists have posited that the asymmetry of jet lag—the increased impact that results from eastward travel compared to westward—is connected to the fact that human circadian rhythms, on average, extend slightly beyond 24 hours.
1 – Anticipate the time change for trips by getting up and going to bed earlier several days before an eastward trip and later for a westward trip. 2 – If you're wearing a watch, change the time to the destination time zone when entering the plane. 3 – Avoid drinking alcohol during your flight.
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.
Why they feel this way is unclear. But scientists recently developed a model that mimics special time-keeping cells in the body and offers a mathematical explanation for why traveling from west to east feels so much worse. It also offers insights on recovering from jet lag.
The Sleep Doctor explains that jet lag is a response to the disruption of your body's normal circadian rhythm, and it's easier to delay your circadian rhythm than to advance it. Therefore, it takes longer to recover from a flight from New York to London than from London to New York.
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.
If you have the choice, try to book a flight that leaves between 8 am and noon and arrives between 6 pm and 10 pm. According to this book, flights that leave late at night (10 pm-1 am) and arrive in the morning (8 am to noon) give a much bigger risk for jet lag.
In addition to shift work, the two types of employees who work on aircraft, pilots (also known as flight deck or flight crew) and cabin crew (also commonly known as flight attendants), regularly experience jet lag.
Flying east or west makes a difference to jet lagYour circadian rhythm (body clock) is less confused if you travel westward. This is because travelling west 'prolongs' the body clock's experience of its normal day-night cycle (the normal tendency of the body clock in most of us is slightly longer than 24 hours).
Most people who have a layover in London try to leave the airport if they have 6 hours or more (depending on which airport you fly into). But there are a few things you should take into consideration on whether you CAN or SHOULD leave the airports to go outside in London.
There are few daytime flights between North America and Europe. This is for many reasons, including the length of the flights, big time zone changes, generally insufficiently large point-to-point traffic to warrant it, less productive aircraft (most have to remain overnight at one end), and so on.
