8 Genius Tips To Avoid Jet Lag On Your Next Trip: An M.D. Explains

One of summertime’s greatest joys? Travel to faraway places. But one of its biggest headaches (other than the TSA lines): jet lag. It’s the traveler’s equivalent of a hangover, with the main difference being that you probably had no fun getting it, and the pain will last longer than the alcohol-induced kind.

Why does jet lag still have such power over us? Well, for starters, rapid time-zone hopping is something our species has been doing for only a matter of decades, so few (if any) of us have fully adapted to this body clock–disrupting aspect of the miracle of flight—and it may take a very long time before anybody does.

Our circadian rhythms, aka our internal clock, affect myriad essential bodily functions, such as blood pressure, when we sleep, when we wake, when hormones (like melatonin) are released, when we poop, and so on. So when we cross multiple time zones, our internal clock—which takes its cues from internal and external factors like light, darkness, temperature, etc.—needs time to adapt to the new location.

A week or two before you go, you may want to try your own body clock–shifting experiment by adjusting your bedtime and rising time by a few hours to start closing the time-zone gap. For example, if you’re headed east from NYC to Western Europe, try moving bedtime and rising time up by an hour or two over the course of several days prior to departure. If you’re headed west and hopping more than three time zones, you may want to try delaying bedtime and rising time.

For those who prefer a more rigorous approach or are crossing numerous time zones, check out Jet Lag Rooster, which generates free step-by-step, customized jet lag–prevention plans, plus suggests best times for bright-light exposure based on your usual sleep times, flight length, time of year, and home and destination locations.

Easier said than done, but try to start your trip in as relaxed a physical and mental state as possible. No matter what age you are, air travel is a physical stressor, so be kind to your body in the week or so prior to departure. Get more rest, eat healthy and clean, get a massage, spend time in the sauna at the gym, and ramp up your meditation practice to prep the body for the challenges ahead.

One more reason to eat a plant-centric diet: It can help fend off jet lag–related digestive troubles, whereas low-fiber, carb-heavy meals tend to stress the digestive system, even more so when you’re crossing multiple time zones. In the air, traditional comfort foods slow your body’s ability to adjust by using up valuable energy (which could be used elsewhere) to tend to the business of breaking down your food.

On long-haul flights, blood tends to pool, particularly in the legs and feet, increasing the likelihood of painful swelling and, for some people, more serious health problems like deep vein thrombosis (DVT).

The best drug-free way to keep problems at bay is to keep circulation moving, as in getting up and walking around the cabin frequently—once an hour is a good rule of thumb. You can also aid circulation by wearing clothes that aren’t constricting or binding; the goal is to encourage circulation, not cut it off at the pass.

Melatonin can be quite helpful for resetting the body clock. I take it myself to prevent jet lag, as do many of my patients who travel frequently. If you’re not familiar with it, melatonin is the hormone that controls your sleep and wake cycle. It’s released at night, when it’s dark, inducing sleep. In supplement form, it can help travelers reset their body clocks a bit more quickly.

When you return home, be patient with your body and expect at least one day of recovery for each time zone crossed. In other words, don’t waste energy trying to fight it. Do expose yourself to as much morning light as you can, and get back to your normal exercise routine to help reset and return your body clock to normal. One final note: Some jet lag is totally normal, and the good news is that it does go away. With every passing day you’ll feel more and more like yourself, so take things slowly and enjoy the journey.
