How to beat jet lag starts with one idea: light and darkness are the levers, and timing them to your destination matters more than any pill or app. Research published in PNAS found that light exposure at the wrong time can delay melatonin and shift your sleep clock - which is exactly what happens when you cross time zones. Here is what works, when to expect it to pass, and how to speed up recovery.
How Do You Beat Jet Lag?
Jet lag happens when your internal clock is out of sync with the local day, and the fastest way to resync it is light at the right times: bright light in the morning at your destination, darkness in the evening. A sleep mask gives you the "darkness" half anywhere - on the plane, in a bright hotel room, or during an afternoon nap you need to keep short - and every option in our silk sleep mask collection is built for exactly that.
Is Jet Lag Worse Going East or West?
East is harder. Flying east means your body needs to go to sleep earlier than it wants, which is harder than staying up later - most people recover from a westward trip in a day or two but need several days going east. Knowing this helps you plan: on eastbound trips, start shifting your schedule a few days before you fly by going to bed earlier in small increments.
When Should You Sleep on the Plane to Avoid Jet Lag?
Sleep on the plane when it is nighttime at your destination. If you land in the morning local time, try to sleep during the overnight portion of the flight so you arrive rested; if you land in the evening, staying awake on the flight helps you sync to local night. A mask makes daytime flights sleepable, and our how to sleep on a plane guide covers the setup in detail.
How Long Does Jet Lag Last?
Most people adjust about one day per time zone crossed, so a six-hour difference usually means four to six days. Recovery is faster with the right light exposure, a consistent local schedule, and short daytime naps (under 30 minutes). Expect the first two days to feel the hardest, then steady improvement.
How to Recover Faster from Jet Lag
Three habits speed recovery: get bright daylight soon after you land, eat and sleep on local time immediately (no "catching up" naps), and protect your sleep with darkness - the black silk sleep mask or navy version from our silk sleep mask collection handles hotel rooms, daytime naps, and early sunrises. For the blackout side of the equation, our 100% blackout sleep mask guide explains how the nose seal stops light leaks, and our silk sleep mask for travel guide has the full packing angle.
The Bottom Line
