If you are attempting to squeeze some journey into the previous couple of weeks of summer season, you will wish to get probably 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 International Desk and obtained an array of useful solutions from our globetrotting employees.
This story comes from NPR Health, a e-newsletter overlaying the science of wholesome residing. To get extra tales like this, click on right here to subscribe.
For occasion, 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 mild, drink espresso, take melatonin, and many others.,” Greg writes. “It has labored actually, rather well.”
Research on jet lag is restricted, and most of it’s on athletes, who — very like NPR’s journalists — are anticipated to jet throughout time zones and carry out at their greatest. A current consensus assertion to assist athletes handle jet lag and journey fatigue within the journal Sports Medicine, affords few guiding ideas.
David Stevens, a physiologist from Adelaide, Australia, who co-authored the assertion whereas working at a sleep analysis middle at Flinders University, breaks it down. First off, you will wish to perceive the workings of your physique’s circadian rhythms, that’s, our inside 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. Light is crucial one however train, meals and even social cues may set off sleepiness or wakefulness.
Get a head begin
Whether you utilize an app or not, Stevens suggests beginning your time zone adjustment just a few days earlier than your journey begins. “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.

Things get harder whenever you’re heading eastward. “It’s brutal from west to east. It often 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 straightforward for our physique clocks to know, since you get extra drained within the night. “My physique’s going, dangle on, you are meant to be asleep now, why aren’t you asleep?” he says.
But whenever you journey eastward, it’s important to attempt to fall asleep whenever you’re not but drained, and that is simply… complicated to your circadian clock, Stevens says. “The physique’s going, dangle 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 circumstances, Stevens says, prep just a few days earlier than your journey by going to sleep sooner than regular and getting up early to soak up a lot of morning mild.
Onboard sleep methods and aids
Stevens says it is a good suggestion to sleep on the flight in case you can, although the consensus assertion notes it is best to align your sleep with what could be night time in your metropolis of departure, so dozing off comes extra naturally. That can imply a nighttime flight is an effective selection.
Of course falling asleep in a decent airplane seat (wanting upgrading to enterprise class) may be practically unattainable for a few of us. NPR’s Vincent Ni, nonetheless, has onboard shuteye all the way down to a science: “I fill my rucksack with stable however gentle 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 international correspondents, a number of International Desk members reported utilizing substances not naturally discovered within the physique.
“If I have to attempt to sleep on the flight (and it is not tremendous early within the morning – I’m not that unhealthy) then I discover a glass of wine or two is my sleep assist!” 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 probably not a physiological sleep,” and you’ll develop a dependency.
As for alcohol, Stevens says the quick reply is “no.” – it may possibly disrupt sleep. Although he confesses on a current 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.
Once you land: Manage your mild consumption
If keen your self into slumber earlier than the solar goes down is not understanding for you, that is no shock, says Stevens. That’s as a result of mild is crucial of the zeitgebers or time-givers. “When mild hits your retina, the alerts journey via the mind, it goes to the hypothalamus,” which controls melatonin secretion, Stevens says. Melatonin is what makes you’re feeling sleepy, and secretion would not begin till daylight begins to dim on the finish of the day.
Conversely, exposing your self to sunlight early within the day may be an effective way to assist sync your circadian clock to the brand new schedule. “In order to let my physique alter extra shortly, I sometimes spend a variety of time outdoors 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 movement,” writes Central Europe correspondent Rob Schmitz.
Stevens says taking a melatonin pill earlier than mattress, coupled with daylight publicity, may also be an effective way to adapt to a brand new time zone. And do not forget to close off that blue mild 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 power that it is advisable to 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 photographs the subsequent morning” to assist energy via sleeplessness. Stevens warns in case you do make use of caffeine, to be sure you drink it at the least 6 hours earlier than you intend to hit the hay.
Rather than chemical assist, Stevens recommends tapping into different zeitgebers – together with meals consumption, train, and temperature modifications to regulate to a distinct time zone. “Every cell in our physique additionally appears to observe a circadian sample,” he says. So for instance “If you train at a specific time of day, and then you definitely shift whenever you train,” in your new time zone that may be a circadian cue, he says. So can shifting your meal instances.
“My favourite sleep assist is to go for a stroll,” Stevens says. “Even if it is only for an hour, even when it is at night time, I discover going for a stroll, getting a little bit of recent air, that simply type of clears your head,” he says.
