Why let jet lag rob you of precious travel time? When your sleep is disrupted, your energy crashes, your mood suffers, and your mental clarity takes a hit—sometimes for days. After a decade of regular coast-to-coast flights, I’ve developed a system that gets me back to 100% in just 24 hours.
I traveled from New York to San Francisco regularly for work from 2013 to 2022, add to that trips to Portland, Oregon to visit family. Even those 5-6 hour flights with a 3-hour time difference were enough to leave me feeling like a shadow of myself for 3-4 days after landing. I still have vivid memories — nightmares?! — of lying awake at 3:00am in my San Francisco hotel, tossing and turning, knowing I couldn’t afford to be off my game for important meetings. Those brutal 3-4 day recovery periods became my normal.
Here’s what I’ve learned since then: Some of the strategies I’m sharing below, I wasn’t aware of back then. Others I knew about but didn’t prioritize acting on—classic case of knowing what to do but not actually doing it. Sound familiar?
The Big 5 Game-Changers
Choose flights that land before the sun goes down
Get light in your eyes as soon as you can after you land. Any amount of time is helpful. If you can get outside for 20-30 minutes for a walk, even better.
Why it works:
Light is your circadian system’s master reset button. Getting natural light exposure within the first few hours of arrival helps shift your internal clock faster than any other intervention. Even 20 minutes of outdoor light provides 1,000+ lux—far more powerful than indoor lighting at resetting your sleep-wake cycle.
Put your screen away 2-3 hours before you want to go to bed in the new timezone
More time without the screen is always better. Don’t pick it back up if you wake up in the middle of the night. If you’re going to bed early in the new timezone and struggling to wake up in the morning, set an alarm for the time you want your body to naturally wake up, and get outside without sunglasses for 20-30 minutes.
Why it works:
Blue light from screens suppresses melatonin production for 2-3 hours after exposure. By eliminating screens before your target bedtime in the new timezone, you’re allowing your body’s natural sleep hormone to rise on schedule, making it easier to fall asleep at the right time.

Get outside in the morning to set your body’s circadian rhythm
Can’t get out for 20 minutes? Get out for 10. Bonus: take a walk. The dynamic duo of natural light and movement is likely to accelerate your progress.
Why it works:
Morning light exposure is the most powerful circadian reset tool available. It signals to your brain that this is the start of your new day, helping shift your entire sleep-wake cycle forward or backward depending on your travel direction. The combination with movement amplifies the effect by increasing core body temperature—another circadian timing cue.
No caffeine after noon
Try walking, or other movement, as a substitute for caffeine if you feel like you’re hitting a wall. It’s OK to be tired. You’re in the long game for going to bed on time in the new timezone.
Why it works:
Caffeine has a 6-8 hour half-life, meaning afternoon caffeine can still be affecting your sleep quality at bedtime. When you’re already fighting circadian disruption, adding caffeine-induced sleep interference creates a compounding problem that extends your recovery time.
Minimize or eliminate alcohol until your jet lag is gone
Why it works:
Alcohol disrupts sleep architecture, reducing REM sleep and causing more frequent nighttime awakenings. When your circadian system is already confused, alcohol makes it even harder for your body to achieve the deep, restorative sleep needed for jet lag recovery.
Additional Support Strategies
These three tactics work hand-in-hand with the big 5 to accelerate your recovery even further. The more strategies you implement, the more they amplify each other’s effects—think of it as compound interest for your circadian system.
Eat at ‘regular’ times in the new timezone as soon as possible
Don’t forget to hydrate. Drink water, and add raw fruits and vegetables for maximum impact.
Why it works:
Your digestive system is another powerful circadian clock. Eating at local meal times sends timing signals to your body that reinforce the light-based cues you’re giving your brain. This dual approach—light for your brain, food timing for your gut—accelerates the overall reset process.
Don’t stay up late when you have jet lag
There’s nothing wrong with going to bed 1-2 hours earlier than normal the first night after you land. You want to give your body the opportunity for more sleep, not less. You can’t do that if you’re still awake at 11pm.
Why it works:
Sleep debt compounds jet lag recovery time. When you’re already fighting circadian disruption, staying up late creates additional sleep pressure that makes it even harder for your body to establish the new rhythm. Going to bed early gives your system the extra recovery time it needs to reset faster.
If you can avoid planning late night activities on the day of your arrival, do
Take it easy that first night so your body can return to full steam sooner the next and following days.
Why it works:
Your first night sets the tone for your entire recovery. Late activities often involve bright lights, stimulation, and delayed bedtime—all of which work against your circadian reset efforts. Taking it easy allows your body to focus its energy on adaptation rather than managing additional stressors.
Takeaway
Bottom line: jet lag doesn’t have to steal days from your life. These strategies have taken me from 3-4 days of recovery down to a single day. Pick the strategies that fit your travel style, and watch your recovery time shrink from days to hours. Your well-rested, clear-headed future self will thank you.
