StopJetLag's Flight-Aligned Plans Don't Just Ask, "How Do I Avoid Jet Lag?" Ask the more important question: ■ When is my first realistic opportunity for core sleep in sync with destination-time and what needs to happen before then? That's at the heart of StopJetLag's Flight-Aligned™ travel planning. The best biological time to sleep and the time your flights allow it can be very different. Your body clock doesn't know you have a connection to make. StopJetLag does. ■ Jet Lag Science Has to Work With Your Flights "Sleep now" isn't useful advice when you're landing, clearing immigration, changing terminals or boarding another flight. StopJetLag analyzes your itinerary, connections and normal sleep patterns to identify a critical anchor: your first realistic opportunity for destination-time core sleep. Then your plan coordinates what happens before and after it. ■ StopJetLag's Flight-Aligned™ Sleep Method StopJetLag provides personalized timing for: • Sleep & rest • Bright light exposure & avoidance • Meals—timing, type & size • Caffeine use & avoidance • Light exercise • Optional melatonin • Transitioning to destination time These recommendations aren't the endpoint-Their coordination with your flights is of primary importance. A sleep recommendation can't ignore when you have to board. Caffeine can't ignore when you need to sleep. None should act as though your connections don't exist. ■ Every Connection Changes What Is Possible An ideal time to sleep is useless if you have to be awake to change planes. A sleep opportunity can disappear because you need to deplane, clear immigration and board again. That's why connections aren't footnotes in a StopJetLag Plan. They help determine the plan. The goal isn't a perfect schedule on paper. It's one you can actually follow. ■ What Happens Before Core Sleep Matters The hours before your first destination-time core sleep matter—when you sleep, stay awake, seek or avoid bright light, eat, use caffeine, exercise and, if you choose, take melatonin. StopJetLag coordinates these influences with your itinerary so they work together rather than as disconnected jet lag tips. The flight itself becomes part of your adjustment strategy. ■ When to Sleep—and When Your Flights Won't Let You. You need enough sleep. Your body clock also needs to move toward destination time. Getting every possible hour of sleep isn't necessarily the same as sleeping at the most useful times. StopJetLag identifies practical sleep opportunities while keeping you awake when your itinerary requires it. The question isn't simply, "Can I sleep?" It's "Is this the right sleep opportunity for where my body clock needs to go next?" ■ Built Around Your Real Trip Your plan can account for departures, arrivals, connections, multi-stop itineraries, normal sleep patterns, practical sleep opportunities, destination time and important events you provide. Trip Notes address itinerary-specific timing issues. StopJetLag Mobile keeps your recommendations available while you travel. ■ Why StopJetLag's Flight-Aligned™ Plans Matter Most jet lag advice tells you what affects your body clock. The harder problem is knowing when you can realistically use those influences. Jet lag advice asks what your body needs. StopJetLag's Flight-Aligned™ planning asks when your journey will actually let you do it. StopJetLag builds your plan around the answer. ■ What Travelers and the Press Have Said Katie Couric Show: "There's a great service called StopJetLag" United Airlines Hemispheres: "The best approach is StopJetLag" Clare Vooght—iNews: "The best app by a million (air) miles...was StopJetLag" ■ StopJetLag on Your Next Trip Don't settle for jet lag advice that assumes your journey will cooperate. Start with your flights. Find your first realistic opportunity for destination-time core sleep. Coordinate what happens before it. Protect what happens after it. That's StopJetLag's Flight-Aligned™ travel planning.
