Travel & Jet Lag FAQs

1.    How does HumanCharger help with jet lag?

Jet lag occurs when your body's internal biological clock (circadian rhythm) remains synchronized with your departure time zone rather than your destination time zone. Because light is one of the strongest signals controlling your circadian rhythm, properly timed light exposure helps your body adjust more quickly to a new schedule.

The HumanCharger delivers bright, full-spectrum, UV-free light through the ear canals. Research has demonstrated that transcranial bright light can support alertness, reaction time, mood, and circadian rhythm regulation. Many travelers using the HumanCharger report adapting to their new time zone more quickly.

2. When should I begin using it before travel?

We recommend beginning your HumanCharger sessions based on the morning at your destination time zone. If you're crossing multiple time zones or traveling internationally, following the recommended HumanCharger Jet Lag Travel Protocol upon arrival and during the first two days of your trip provides the greatest benefit.

Keep this in mind: Light is a primary cue for resetting the body clock. The HumanCharger helps your internal clock adjust faster to the destination time zone, whether it’s sunny or cloudy.

3. How often should I use it after landing?

Our Jet Lag Protocol recommends using HumanCharger approximately every two hours while you're awake during your first two days after arrival. Most travelers complete four to five sessions per day during this adjustment period.

Once your body has adapted to the new time zone, you can return to your normal daily routine of one HumanCharger session each morning upon waking.

4. Does it work for eastbound and westbound travel?

Yes. Whether you're traveling east or west, your body still needs to adjust to a new light-dark schedule. The HumanCharger is designed to support your body's natural adaptation to changing time zones.

Some travelers find eastbound travel more challenging because it requires advancing the body's internal clock, while westbound travel often involves delaying it. Following the recommended HumanCharger Jet Lag Protocol can help support adjustment in either direction.

5. Is it useful for business travelers?

Absolutely. Business travelers often need to perform at a high level immediately after landing, whether attending meetings, making presentations, negotiating contracts, or making important decisions.

Maintaining alertness, focus, and energy while adapting to a new time zone is one reason frequent business travelers include the HumanCharger in their travel routine.

6. Can flight crews use it?

International pilots, flight attendants, and other flight crew members experience the same frequent time zone changes as regular travelers. They often face irregular work schedules that challenge their circadian rhythms.

The HumanCharger is used by pilots, flight attendants, and other flight crew members looking to maintain alertness and adapt more effectively to changing schedules. As with any fatigue-management strategy, crew members should always follow their airline's policies and applicable aviation regulations.

7. Can athletes use it while traveling?

Yes. Athletes often travel across multiple time zones for training or competition, making rapid adaptation critical for peak performance.

The HumanCharger is used by professional and elite athletes to support alertness and adaptation after long-haul travel. Coaches and athletes often include light management as one part of an overall training and recovery strategy.

8. Will it shorten recovery after long-haul flights?

Many users report feeling more alert and adapting more quickly after long-haul flights when following the recommended HumanCharger Jet Lag Protocol. Individual results vary, and recovery depends on several factors, including the number of time zones crossed, sleep, hydration, and overall health.

While no product can eliminate every effect of long-haul travel, supporting your body's natural circadian rhythm can help make the adjustment process easier.

9. Can I use the HumanCharger during my flight?

The HumanCharger is designed to help your body adapt to time zone changes upon arrival or during long layovers. There are instances where your destination morning occurs mid-flight. The number one rule when flying across time zones is to set your watch or phone to the destination time zone. It’s your first task after boarding the aircraft for your flight.

For example, if you are flying from Munich to Chicago and halfway across the ocean, Chicago time becomes 8:00 am. Since this is your new destination time zone, you would start your first HumanCharger session. Then use it once every two hours, up to five times that day and again the following day. Again, everything in your world revolves around the new destination time zone.

Remember, the goal isn't simply to stay awake during your journey - it's to help your body adjust more quickly to its new time zone upon arrival.

10. What if I'm traveling through multiple time zones?

The more time zones you cross, the greater the challenge for your body's internal clock. Long-haul international travel often requires several days for your circadian rhythm to fully adapt, especially when traveling east.

The HumanCharger is designed to support your body's natural adjustment process by providing one of the strongest biological signals that regulate your circadian rhythm: light. Following the recommended HumanCharger Jet Lag Protocol during the first two days after arrival will help you feel more alert while your body adapts to the new schedule.

Every traveler responds differently, but maintaining a consistent routine - including light exposure, hydration, adequate sleep, and good nutrition - can make adjusting to multiple time zones easier.
