Taylor Swift brought about a stir after the Tremendous Bowl this 12 months by answering a query about her flight (on her personal jet, no much less) from Tokyo to Las Vegas. When her boyfriend Travis Kelce of the Kansas Metropolis Chiefs requested her “how do you not have jet lag proper now?” she responded, maybe jokingly, “jet lag is a selection.”
However sleep specialists like Jade Wu would love Swift and others to know that “jet lag could be very actual. It is biologically ingrained.”
Jet lag is a type of circadian misalignment, an umbrella time period for any time your physique clock is out of sync along with your present time zone or the place the solar is within the sky, says Wu, a behavioral sleep medication psychologist and researcher at Duke College.
It occurs whenever you cross a number of time zones in a really brief period of time, she says. A direct flight from Tokyo to Las Vegas, for example, takes about 10 hours and units your inside clock ahead by 17 hours (in Customary Time). So should you land in Las Vegas at 7 p.m., your physique may nonetheless be on Tokyo time, which is midday the following day.
What occurs to your physique throughout jet lag
For a lot of of us, jet lag can depart them feeling groggy and out of sync with their environment. “Our pondering is slower, our temper is worse, our metabolism just isn’t pretty much as good. We won’t sleep once we wish to sleep however we will not really feel awake once we wish to be awake,” says Wu.
That is as a result of nearly every part in our our bodies — like our blood strain, our organ methods and our cognitive operate — runs on an inside clock, says Wu. “These clocks are synced up to one another. Throughout jet lag, out of the blue all these clocks are confused. They’re saying: ‘Wait a second, I assumed it was daytime. Why is it evening?’ ”
That features the grasp clock in your mind known as the suprachiasmatic nucleus (SCN). “Consider all of the clocks in your physique as a billion-person orchestra. The SCN is the maestro. And if the maestro cannot hold time, then your entire orchestra falls aside,” she says.

How one can decrease jet lag signs
To mitigate the results of jet lag, a little bit preparation goes a good distance, says Wu. Listed below are some suggestions to assist handle signs of grogginess.
- Relaxation up beforehand. Take supplemental naps forward of your journey, however do not drive it should you’re not sleepy. The purpose is to get as a lot relaxation as attainable in order that whenever you’re in a interval of much less sleep, you may really feel a little bit extra alert.
- Time shift your sleep. Progressively regulate your schedule towards your goal time zone earlier than you permit. For example you reside in Chicago and your regular bedtime is at 11 p.m. and also you’re touring to Lisbon, Portugal, in per week. Begin heading to mattress (and getting up) about 15 to half-hour earlier every day. By the point your journey rolls round, your bedtime must be about 8 p.m. How does that assist with the time change? Slightly than attempting to go to sleep at 5 a.m. Lisbon time (11 p.m. Chicago time), you may now be attempting to go to sleep at 2 a.m. Lisbon time — a extra cheap hour to hit the hay.

In case you’re flying to Taipei, Taiwan, from Los Angeles, for instance, take a really late flight so you will get your eight hours of nighttime sleep on the 14-hour aircraft journey. Whenever you arrive, it will be morning native time, and you will have sufficient relaxation to begin your day.
- Watch out with alcohol and caffeine. Alcohol can block or intervene with deep sleep, making sleep extra fragmented. And Wu discourages utilizing caffeine to battle jet lag as a result of it might probably result in unpredictable outcomes. Typically it might probably make you exhausted or wired or each. Nevertheless, should you’re heading east, you would intention to have some caffeine to assist keep up. Keep away from it should you’re going west.
- Think about the route you are headed. In case you’re going west, say to Seoul, you may have to remain up and get up later. In case you’re going east, say to Madrid, you may should sleep and get up earlier. “Going west is less complicated as a result of your physique [naturally] needs to go to mattress later. Going east is tough as a result of it’s important to battle [sleep],” says Wu.
In case you’re touring west, take a brief nap on the flight so you’ll be able to go to mattress at an affordable hour when you attain your vacation spot. By the point you land, hopefully you may be sleepy sufficient to “sleep a pleasant, strong evening and get up within the morning native time,” says Wu.
In case you’re touring east, attempt to keep up throughout your flight. “Whenever you land, you are not going to be sleepy but by the native bedtime. So you could have to take a sleep assist that will help you go to sleep that evening,” she says.
- When you attain your vacation spot, shortly attempt to regulate to the native time. “Get plenty of gentle very first thing within the morning,” says Wu. Exposing your self to sunlight early within the day might help sync your circadian clock to your new time zone. “Go outdoors, train, stroll, hike, go round city. The faster you get actively engaged within the rhythm of the native schedule, the extra shortly you may regulate.”
