As a basic precaution, nevertheless, Dr. Varga doesn’t suggest taking both melatonin or a sleeping tablet for the primary time on a aircraft, provided that each might sometimes trigger opposed results in some folks. (And it’s finest to not discover out that you simply’re a kind of folks when you’re trapped at 30,000 toes.)

Being at excessive altitude on a aircraft may also put you extra in danger for unwanted effects from a sleeping tablet or melatonin when you have one other medical situation affected by altitude, says Dr. Varga. “For instance, sleep apnea could be worsened by sleep medicines resulting from their muscle-relaxant results, and dips in oxygen associated to apnea may also be worse on a aircraft as a result of altitude, even in a pressurized cabin,” he says. However in any other case, should you’ve beforehand taken melatonin or a sleeping tablet with out unwanted effects, you’ll be able to really feel protected taking it on a aircraft, too.
Doing so successfully, nevertheless, requires some forethought.

Find out how to safely and successfully use sleeping tablets or melatonin for flights
Melatonin
As a result of melatonin works by phase-shifting your circadian rhythm (aka signaling to the physique that it’s time for sleep even when it isn’t darkish out), it solely is smart to take it on a aircraft “if the flight is occurring throughout a time if you would usually be sleeping within the vacation spot time zone,” says sleep specialist Angela Holliday-Bell, MD. On this manner, melatonin will help stave off jet lag by permitting you to transition to the sleep schedule of your goal time zone earlier than arriving.
So, flights that occur in a single day inside the identical or related time zones (lengthy north-south flights) and flights that go east or west by a number of time zones (so that you simply’d basically miss an evening of sleep with out sleeping on the aircraft) would qualify. Once more, the best solution to keep in mind it’s, should you’re on the aircraft when it’s nighttime (that’s, sleeping time) in your goal vacation spot, you’ll be able to take melatonin. However in any other case, you’d be throwing off your circadian rhythm to take action.
For instance, take a flight to Tokyo from New York, the place you’re leaving mid-morning (when it’s round 1 or 2 a.m. Tokyo time) and arriving in Tokyo the subsequent day, in the midst of the afternoon native time. In that case, it makes circadian sense to sleep on the aircraft—and take melatonin, should you want, so as to take action—since you’re flying when people in Tokyo are asleep, and will probably be daytime if you arrive. However should you had been flying to London from New York throughout the daytime, leaving within the morning round 8 a.m., you’d be within the air when it’s mid-afternoon in London—which isn’t a time if you’d sometimes sleep. Should you had been to take melatonin and cross out, your circadian rhythm could be off when you arrived: It’d be round 8 p.m., and also you’d have simply slept by the afternoon, making it more durable to go to sleep that night time.
It’s additionally finest to take melatonin a pair hours earlier than what would usually be your bedtime, to be able to give it time to kick in. So, within the Tokyo instance, in case your normal bedtime is midnight, you’d wish to take melatonin a pair hours earlier than boarding, so that you’d (hopefully) be sleeping proper after takeoff (which is close to your bedtime, Tokyo time). Whereas, should you had been heading to, say, Athens, and also you had been leaving at midday New York time (aka 7 p.m. Athens time), you’ll wish to wait a pair hours into the flight to take melatonin, so that you aren’t sleeping a number of hours earlier than if you would’ve been going to mattress in Athens.
As for the dosage, it’s finest to stay to the everyday dose you’ve taken beforehand (and to not go any greater for the flight). A great reference vary is between 0.5 and three mg, says Dr. Holliday-Bell. (Although many melatonin dietary supplements can be found in dosages as excessive as 5 mg and past, taking an excessive amount of melatonin elevates the chance of unwanted effects and dependency.)
Sleeping tablet
To reiterate the above, it’s solely a good suggestion to take a sleeping tablet on a aircraft should you’ve taken one earlier than with no unwanted effects and also you would not have a medical situation affected by altitude. Past these {qualifications}, the identical timing rule for taking melatonin on a aircraft additionally applies to a sleeping tablet—that’s, you solely wish to take it (and be asleep) throughout a time if you would usually be sleeping within the vacation spot time zone. However with a sleeping tablet, you’ll be able to take it nearer to if you’d like to truly go to sleep.
Completely different from melatonin, most sleeping medicines “are metabolized comparatively shortly,” says Dr. Varga, “which means that elevated sleep propensity ought to begin inside 20 to half-hour of taking it.”
That actuality could make it tempting to only pop a sleeping tablet to be able to cross a couple of hours of a flight snoozing—however once more, you’d be higher off solely taking separately if you would sometimes be asleep within the place the place you’re headed, in order to not throw off your circadian rhythm and worsen your jet lag when you arrive.
As a result of sleeping tablets (particularly prescription ones) can have a stronger drowsiness-inducing impact than melatonin, it’s additionally sensible to solely take one on a aircraft when you have at the very least seven hours remaining of the flight. That stated, should you wanted to be awoken throughout that point window after taking a sleeping tablet, it will be doable (most sleeping tablets should not so potent as to make somebody “fully un-arousable,” says Dr. Varga), however you’d definitely really feel groggy and foggy. And that would intervene together with your functioning, in addition to make it unsafe to do issues like function a automobile, says Dr. Holliday-Bell.
