Interesting article, thanks Mardee! And yes, it works for me.
I laughed at the NYT article which quotes Taylor Swift as saying "Jet lag is a choice". Thanks Taylor but I'll take science-based advice and go with the fact that adjusting your circadian rhythm is determined by light exposure.
This last trip I had a different flight schedule and was worried whether Timeshifter would work. I flew Spokane -> Atlanta (4.5 hour flight), a 3-ish hour layover in ATL and then ATL -> Edinburgh (turned out to be a 7 hr flight instead of nearly 8). The plan called for me to sleep a couple of hours on the Spokane to ATL flight and then immediately to go to sleep on the ATL to EDI flight. I slept maybe an hour on the Spokane to ATL flight but I kept my eyes shut part of the flight to cut down on the light when I was awake. On the international leg I settled down to sleep about an hour and a half in to the flight but only slept about 3 hours.
On previous flights where I had a 10 hour flight from Seattle or SLC to Western Europe I was able to get as much as 6 hours sleep with some resting with a sleep mask on. I am going with one longer flight instead of 2 shorter flights next time.
I felt fine when I got to EDI, checked in to my hotel and headed for an Afternoon Tea at 3P. I laughed on my TR because that huge, heavy tea made me sleepy so did take a short nap but followed the sunlight recommendations.
I don't have any trouble doing following the sunlight/caffeine/wake up/go to sleep recommendations and yes, I wear sunglasses in the airport if needed. As one of my grandmothers used to say "You won't see anyone you know or care about". I don't/didn't care if others thought I was a dork.
To me it's worth it but it's definitely a personal choice.
