Taylor Swift induced a stir after the Tremendous Bowl this 12 months by answering a query about her flight (on her non-public 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 consultants like Jade Wu would love Swift and others to know that “jet lag may 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 together 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 once you cross a number of time zones in a really quick period of time, she says. A direct flight from Tokyo to Las Vegas, as an illustration, takes about 10 hours and units your inside clock ahead by 17 hours (in Commonplace Time). So when you land in Las Vegas at 7 p.m., your physique would possibly nonetheless be on Tokyo time, which is midday the subsequent day.
What occurs to your physique throughout jet lag
For a lot of of us, jet lag can go away them feeling groggy and out of sync with their environment. “Our considering is slower, our temper is worse, our metabolism will not be pretty much as good. We won’t sleep after we need to sleep however we will not really feel awake after we need to be awake,” says Wu.
That is as a result of virtually all the pieces in our our bodies — like our blood stress, 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, instantly all these clocks are confused. They’re saying: ‘Wait a second, I believed it was daytime. Why is it night time?’ ”
That features the grasp clock in your mind referred to 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 maintain time, then your complete orchestra falls aside,” she says.

Methods to decrease jet lag signs
To mitigate the results of jet lag, a bit preparation goes a great distance, says Wu. Listed here are some suggestions to assist handle signs of grogginess.
- Relaxation up beforehand. Take supplemental naps forward of your journey, however do not pressure it when you’re not sleepy. The objective is to get as a lot relaxation as doable in order that once you’re in a interval of much less sleep, you will really feel a bit extra alert.
- Time shift your sleep. Steadily alter your schedule towards your goal time zone earlier than you permit. As an example you reside in Chicago and your common bedtime is at 11 p.m. and also you’re touring to Lisbon, Portugal, in every 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? Quite than making an attempt to go to sleep at 5 a.m. Lisbon time (11 p.m. Chicago time), you will now be making an attempt to go to sleep at 2 a.m. Lisbon time — a extra cheap hour to hit the hay. In case you need assistance with this step, attempt utilizing jet lag apps like Time Shifter to create a schedule.
- Guide a flight that works together with your nighttime sleep schedule, not towards it. 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. If 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 intrude with deep sleep, making sleep extra fragmented. And Wu discourages utilizing caffeine to battle jet lag as a result of it might result in unpredictable outcomes. Typically it might make you exhausted or wired or each. Nonetheless, when you’re heading east, you can goal to have some caffeine to assist keep up. Keep away from it when you’re going west.Â
- Contemplate the path you are headed. In case you’re going west, say to Seoul, you will have to remain up and get up later. In case you’re going east, say to Madrid, you will need to sleep and get up earlier. “Going west is simpler as a result of your physique [naturally] needs to go to mattress later. Going east is difficult as a result of you must battle [sleep],” says Wu.Â
In case you’re touring west, take a brief nap on the flight so you’ll be able to go to mattress at an inexpensive hour when you attain your vacation spot. By the point you land, hopefully you will be sleepy sufficient to “sleep a pleasant, strong night time and get up within the morning native time,” says Wu.
In case you’re touring east, attempt to keep up throughout your flight. “If you land, you are not going to be sleepy but by the native bedtime. So you could have to take a sleep help that can assist you go to sleep that night time,” she says.
- When you attain your vacation spot, rapidly attempt to alter to the native time. “Get a lot of gentle very first thing within the morning,” says Wu. Exposing your self to sunlight early within the day may 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 rapidly you will alter.”
