If you happen to’re making an attempt to squeeze some journey into the previous couple of weeks of summer time, you will wish to get essentially the most out of your trip. And nothing ruins a visit to the Louvre or a scuba-diving tour like your physique telling you it is time for mattress NOW. So are you able to “hack” jet lag, so to talk? Or at the least mitigate it?
We posed the query to NPR’s Worldwide Desk and received an array of useful solutions from our globetrotting workers.
This story comes from NPR Well being, a e-newsletter protecting the science of wholesome dwelling. To get extra tales like this, click on right here to subscribe.
As an illustration, NPR producer Greg Dixon is obsessed with an app for jet lag known as Time Shifter. “You enter your journey schedule and it spits out a plan for a pair days earlier than and a pair days after your flights, advising you when to get/keep away from pure gentle, drink espresso, take melatonin, and so forth.,” Greg writes. “It has labored actually, very well.”
Analysis on jet lag is proscribed, and most of it’s on athletes, who — very similar to NPR’s journalists — are anticipated to jet throughout time zones and carry out at their greatest. A latest consensus assertion to assist athletes handle jet lag and journey fatigue within the journal Sports activities Drugs, presents few guiding rules.
David Stevens, a physiologist from Adelaide, Australia, who co-authored the assertion whereas working at a sleep analysis heart at Flinders College, breaks it down. First off, you will wish to perceive the workings of your physique’s circadian rhythms, that’s, our inner clock that tells us when it is time to go to sleep and when to get up.
Then you may reap the benefits of what sleep researchers name zeitgebers or time-givers, exterior components that set the tempo of those rhythms. Gentle is an important one however train, meals and even social cues may set off sleepiness or wakefulness.
Get a head begin
Whether or not you utilize an app or not, Stevens suggests beginning your time zone adjustment a couple of days earlier than your journey begins. “Considered one of your greatest methods to organize for any westward journey is you simply fall asleep, for instance, an hour later every night time,” Stevens says. And go forward and permit your self to remain in mattress an hour later every morning as effectively.

Issues get harder while you’re heading eastward. “It is brutal from west to east. It normally takes me 10 days to regulate, say from Washington to Tokyo,” writes NPR’s Asia editor Vincent Ni.
Stevens says there is a easy rationalization for this. Going to mattress later than regular – as you do when touring westward – is comparatively simple for our physique clocks to grasp, since you get extra drained within the night. “My physique’s going, hold on, you are meant to be asleep now, why aren’t you asleep?” he says.
However while you journey eastward, it’s important to strive to fall asleep while you’re not but drained, and that is simply… complicated to your circadian clock, Stevens says. “The physique’s going, hold on, you are not meant to be asleep but. What are you doing?” And to make issues worse, one of many physique’s peak efficiency instances, after we’re naturally most alert, is round 7 p.m., he provides.
So in these instances, Stevens says, prep a couple of days earlier than your journey by going to sleep sooner than regular and getting up early to soak up a number of morning gentle.
Onboard sleep tips and aids
Stevens says it is a good suggestion to sleep on the flight if you happen to can, although the consensus assertion notes it is best to align your sleep with what can be night time in your metropolis of departure, so dozing off comes extra naturally. That may imply a nighttime flight is an efficient alternative.
After all falling asleep in a decent aircraft seat (in need of upgrading to enterprise class) will be practically unimaginable for a few of us. NPR’s Vincent Ni, nonetheless, has onboard shuteye right down to a science: “I fill my rucksack with strong however smooth materials, put it on the tray (in financial system class) and lay my brow on it. Key for me is the eyeshade and ear plugs.”
Now as you may anticipate for a gaggle of travel-hardened overseas correspondents, a number of Worldwide Desk members reported utilizing substances not naturally discovered within the physique.
“If I must attempt to sleep on the flight (and it isn’t tremendous early within the morning – I am not that dangerous) then I discover a glass of wine or two is my sleep support!” writes Beirut-based correspondent Ruth Sherlock. Others talked about taking prescription sedatives like zolpidem (Ambien) to nod off.
Stevens recommends in opposition to prescription sedatives as a result of “it is not likely a physiological sleep,” and you’ll develop a dependency.
As for alcohol, Stevens says the quick reply is “no.” – it could possibly disrupt sleep. Though he confesses on a latest journey to London that he “could have had a pint as quickly as I landed, however that was at about 4 o’clock within the afternoon,” In different phrases, a very good 6 hours earlier than bedtime.
When you land: Handle your gentle consumption
If keen your self into slumber earlier than the solar goes down is not figuring out for you, that is no shock, says Stevens. That is as a result of gentle is an important of the zeitgebers or time-givers. “When gentle hits your retina, the alerts journey by the mind, it goes to the hypothalamus,” which controls melatonin secretion, Stevens says. Melatonin is what makes you’re feeling sleepy, and secretion does not begin till daylight begins to dim on the finish of the day.
Conversely, exposing your self to sunlight early within the day will be a good way to assist sync your circadian clock to the brand new schedule. “With a view to let my physique alter extra shortly, I sometimes spend a number of time exterior within the full daylight if I can (in hotter months) or within the daylight inside (in colder months) to remind my physique of the brand new environment and to let the melatonin stream,” writes Central Europe correspondent Rob Schmitz.
Stevens says taking a melatonin pill earlier than mattress, coupled with daylight publicity, can be a good way to adapt to a brand new time zone. And do not forget to close off that blue gentle in your cellphone, too.
Naps, meals and train
NPR’s deputy worldwide editor Nishant Dahiya and China correspondent John Ruwitch each swear by staying awake till 9 p.m. at your vacation spot – irrespective of how cruddy you’re feeling – and Stevens says that is a very good rule of thumb.
In reply to my anxious plea “Are naps allowed?!” Stevens says they are often useful. “Naps can provide the little perk of vitality that you should then final an additional couple of hours.” The catch? He recommends capping your snooze at 20 minutes.
Dahiya additionally depends on “greater than three espresso pictures the subsequent morning” to assist energy by sleeplessness. Stevens warns if you happen to do make use of caffeine, to be sure to drink it at the least 6 hours earlier than you intend to hit the hay.
Slightly than chemical assist, Stevens recommends tapping into different zeitgebers – together with meals consumption, train, and temperature modifications to regulate to a special time zone. “Each cell in our physique additionally appears to comply with a circadian sample,” he says. So for instance “If you happen to train at a selected time of day, and then you definitely shift while you train,” in your new time zone that may be a circadian cue, he says. So can shifting your meal instances.
“My favourite sleep support is to go for a stroll,” Stevens says. “Even when it is only for an hour, even when it is at night time, I discover going for a stroll, getting a little bit of contemporary air, that simply type of clears your head,” he says.
