Every trip past four or five timezones comes with the same TikTok flooding your For You page: a supplement stack, a "protocol," someone's very specific instructions for what to do in the airport bathroom before boarding. Some of it is genuinely useful. Most of it is theater. Here's the actual sort.
What actually helps
Get on local time immediately, not gradually. The moment you land, start acting like it's the time it actually is there, not the time your body thinks it is. Eat when locals eat, sleep when locals sleep, even if your body is screaming that it's the wrong decision. Your circadian rhythm takes its cues from behavior as much as from light, and the fastest way to reset it is to stop negotiating with it.
Light exposure timing matters, and it's free. Morning sunlight helps shift your body clock forward, evening light shifts it back. If you've flown east and landed feeling wide awake at 4am, getting outside for daylight as early as you can genuinely helps pull your rhythm into place faster than staying in a dark hotel room waiting to feel sleepy. This is the one piece of jet lag advice that's both well-established and completely free, which is probably why it doesn't trend on TikTok as hard as anything with a product attached.
Stay hydrated, skip the alcohol on the flight. Cabin air is dry, and dehydration makes every jet lag symptom worse, the grogginess, the headache, the general sense of being assembled from spare parts. Alcohol makes it worse twice over: it dehydrates you further and disrupts whatever sleep you do manage on the plane. Neither of these is a hack. They're just not doing the thing that makes it worse.
Shift your schedule a couple of days before you fly, if you can. Nudging your sleep and meal times an hour or two toward your destination's schedule before you even leave gives your body a head start. It's not always practical, especially on a short trip, but if your schedule allows it, it's real and it works.
What's mostly theater
Melatonin megadosing. Melatonin can help signal to your body that it's time to sleep, at the right time, in a reasonable amount. What's trending is a different thing: stacking way more than a reasonable amount on the logic that more must work better. It doesn't work that way with a hormone your body already produces on its own schedule, and we're not going to tell you a specific number here because that's exactly the kind of confident-sounding advice that gets repeated past the point anyone checked if it was true.
Elaborate pre-flight "protocols." The 12-step lists, the specific compression sock and eye mask and supplement combination timed to the minute, the ones that look like a pilot's pre-flight checklist. If it makes you feel more in control before a long flight, fine, that's a real benefit. But there's no version of "12 very specific things in a very specific order" that outperforms "sleep when it's night where you're going, get outside, don't dehydrate yourself." The complexity is the product, not the result.
Fully "beating" jet lag on a short trip. If you're crossing six or more timezones for four days, you are probably not going to feel 100% the entire time, and no amount of pre-planning changes that math. This isn't pessimism, it's just useful to know going in so you don't plan the first day like you'll be sharp.
The unglamorous truth
None of the stuff that actually works is exciting enough to go viral. It's daylight, water, and not fighting your new time zone. The stuff that does go viral is exciting specifically because it sounds like a hack, and hacks are more shareable than "be a little disciplined about sleep and sunlight for 48 hours."
One practical way this shows up in how you should actually plan a trip: build slack into the first day or two after a long-haul flight instead of front-loading your itinerary with everything. In Routely, that's as simple as setting a chiller pace for the first couple of days and letting things pick up once you've actually landed on local time, rather than fighting your own body clock on day one.
