Circadian science has long been integral to enhancing the safety and performance of astronauts on space missions. Meticulously designed circadian plans aid astronauts in mitigating jet lag during training visits, aligning with rocket launch schedules, and regulating their day-night cycles aboard the International Space Station. These plans also include adjustments for spacewalks, docking, and undocking. Mission controllers, too, are equipped with circadian plans to ensure around-the-clock support, maintaining an uncompromised safety standard.

Since 2010, Dr. Steven W. Lockley, a world-renowned authority on circadian rhythms and sleeps, has provided NASA with expert circadian guidance, collaborating with NASA Flight Surgeon Dr. Smith L. Johnston and other colleagues. In 2017, Dr. Lockley met Mickey Beyer-Clausen, a Danish technology entrepreneur, and Jacob Ravn, an award-winning UX designer, in New York. They recognized their combined expertise could democratize Dr. Lockley’s science-based circadian plans. Early investors and advisors, including Dr. Johnston, former NASA Astronaut Mike Massimino, and Chief Astronaut at Axiom Space, Michael Lopez-Alegria, saw firsthand the benefits of Dr. Lockley’s circadian solutions.

In 2018, Timeshifter unveiled its first product, which has become the world’s most-downloaded and highest-rated jet lag app. Data from over 360,000 post-flight surveys indicated that 96.4% of the travelers who followed Timeshifter's advice did not struggle with severe or very severe jet lag. When NOT following the advice, there was a 6.2x increase in severe or very severe jet lag, and a 14.1x increase in very severe jet lag. Recently, Timeshifter launched a new app aimed at shift workers, who comprise at least 20% of the global workforce and often struggle with constantly changing schedules or a lack of adaptation to new ones.

Timeshifter’s ambitions extend beyond jet lag and shift work, aiming to tackle various circadian disorders, enhance peak performance and circadian balance across diverse areas of life, and then to the entire medical field given the unity of circadian rhythms in our physiology and metabolism. The importance and health impact of timing when we sleep, eat, exercise, go to school and work, take medications and vaccines, have blood samples taken, or even when to have surgery, opens up an enormous opportunity far bigger than the emerging but multi-billion dollar sleep revolution. Timeshifter is at the head of this circadian revolution.
