The underlaying cause of jet lag.

 
Jet lag is caused when the sleep/wake and light/dark cycle shift too quickly for our circadian clock to keep up
 
 

Most life on earth is adapted to the daily light/dark cycle caused by the rotation of our planet. We have an internal, 24-hour circadian clock located in a part of the brain called the hypothalamus that helps us manage the regular rhythm of our day. Jet lag is caused when the sleep/wake and light/dark cycle shift too quickly for our circadian clock to keep up.

The real consequences of jet lag.

 

Some travelers may not recognize how greatly jet lag affects them. Unfortunately, jet lag is not just about feeling “off” for a couple of days. In reality, the consequences are wide-ranging and can be quite significant.

We have being doing it all wrong.

There are an incredible number of misconceptions out there on how to deal with jet lag:

  • “Get as much sleep as possible on the plane”

  • “Stay hydrated and enjoy only certain foods”

  • “Use sleep medication”

  • “Get onto local time as soon as possible”

  • “Get out in the sun if arriving during the day”

  • “Use caffeine to power through”

Unfortunately, no generic solution can help you tackle the underlying cause of jet lag, and might even be counterproductive, making your jet lag worse!

It’s time to replace guessing with science.

 
 

The key to quick adaptation is light.

 
 

Surprising to many, light is the most important time cue for resetting your circadian clock. Managing when you see and avoid light is critical to timeshifting your clock quickly. The right light exposure at the right time can significantly accelerate your adaptation to a new time zone. Seeing light at the wrong time will make your jet lag worse.

Supplemental melatonin speeds up adaptation.

 
 

In addition to light, the right type and dose of melatonin, at the right time, can help you shift faster and sleep better.

 
Use of melatonin can help you to fall asleep more easily, stay asleep longer, and speed up adaptation to a new time zone

Ways to increase your energy level while traveling

 
 
 
Get energy from caffeine without disrupting your sleep

Caffeine

Caffeine is a powerful stimulant and can help you stay awake at times when you should see light, to help reset your clock more quickly. But be careful, using caffeine at the wrong time can have negative effects on your sleep quality.

 
Naps can be an additional tool to help maintain high levels of alertness and performance

Napping

Naps can be an additional tool to help maintain high levels of alertness and performance but they need to be scheduled at the right time to give you maximum recovery without affecting your scheduled night-time sleep.

 

You are unique.
So is your jet lag.

"The problems caused by jet lag cannot be tackled using generic advice, which is oversimplistic and can often be counterproductive, making jet lag worse. Each traveler and trip is different and requires a personalized approach taking your sleep pattern, chronotype, flight plan, and a range of personal preferences into account."

Jet lag is history with Timeshifter

 

With Timeshifter, you can create your own personalized jet lag plans, based on the latest research in sleep and circadian neuroscience. The same technology used by astronauts and elite athletes to perform at their best, is now available to you.

 
 
 
 
 
 
Mike Massimino, former NASA astronaut.
 

"Astronauts are always looking for anything that can give extra bandwidth, focus, and energy for the crucial moments. It's critical to avoid costly mistakes and can even affect our survival. When I was an active astronaut at NASA, I used the same science-based circadian algorithm as Timeshifter is deploying in their app. When on missions, it helped me prepare for launches at odd hours, and to perform at my best on orbit. On earth, it helped me to eliminate jet lag when traveling to train in time zones as disparate as the U.S., Japan and Russia.

I can’t recommend Timeshifter enough.”
