Six Senses Hotels Resorts Spas has partnered with Timeshifter, a jet lag app developed by Harvard Medical School associate professor Seven Lockley based on the latest research on sleep and circadian neuroscience.

Timeshifter offers personalised jet lag plans based on the traveller's sleep pattern, chronotype, flight plan, and optional preferences such as pre-travel adjustment or the use of melatonin for faster adaptation.

The app incorporates a real world "practicality" filter, designed to make the advice realistic and easy to follow; there is also a unique Quick Turnaround feature for business travellers who want to be at their best during short business trips that are not long enough to allow full adjustment. A notification system provides advice, even while in flight.

The algorithm behind the new Timeshifter app has been used to help astronauts, elite athletes, and top CEOs eliminate jet lag.

"We all love to feel good when traveling on business or pleasure, but when flying long distances jet lag can cause stress, fatigue, moodiness and restless nights,” said Neil Jacobs, CEO of Six Senses. “We're delighted to partner with Timeshifter and to provide our guests with a state-of-the-art tool so they can get the most out of their time when staying with Six Senses and to be their best after they arrive back home."

Guests who book a stay through SixSenses.com, via email or phone will be given a special code in their reservation confirmation so they can unlock a complimentary jet lag plan inside the Timeshifter iOS or Android app.

"The partnership between Six Senses and Timeshifter is showing what the future of luxury travel can be,” said Mickey Beyer-Clausen, CEO of Timeshifter. “By combining the Six Senses Integrated wellness experience with the Timeshifter jet lag app, based on the latest in sleep and circadian neuroscience, guests will enjoy their vacations even more and perform at their very best on business trips."
