For ten years, Sleep Cycle has been the world’s most popular sleep tracking application. With millions of active users around the globe, it has also become one of the world’s richest repositories of data on global sleep habits — with years’ worth of data that can be analyzed and dissected by region, season, gender, generation, lifestyle habits, and a number of other variables. All data is anonymous and collected only with the consent of Sleep Cycle users.

The Sleep Cycle Institute puts this data into the hands of a group of multidisciplinary health and wellness experts who examine it to gain a deeper, quantitative insight into how travel, stress, exercise, holidays, school and work schedules, and other lifestyle choices affect the quality of our sleep.

The goal of the Sleep Cycle Institute is to educate individuals about why sleep must be made a higher priority to achieve greater overall health and well-being and, ultimately, even to help shape public policy around sleep.

Dr. Frida Rångtell, Ph.D., is a doctoral student in the Department of Neuroscience at Uppsala University, Sweden. Her research is mainly focused on the relationship between sleep and memory, but also covers a variety of other sleep-related topics such as sex-differences in sleep and effects of sleep loss, as well as how the use of technology and screens close to bedtime can impact our sleep.

“Unraveling the mysteries of sleep is my passion,” said Rångtell. “Sleep is fascinating, and teaching people about it is exciting and important. Being a part of the Sleep Cycle Institute is a great opportunity to spread the knowledge about sleep and how it contributes to mental and physical well-being.”

Dr. Catherine Darley is the founding director of The Institute of Naturopathic Sleep Medicine, Inc in Seattle, Washington, USA. Her focus is on the naturopathic treatment of sleep disorders in children and adults, particularly those with insomnia and circadian rhythm disorders. Part of her mission is to up-level public awareness of the importance of sleep health, and teach sleep skills to groups of all kinds. Dr. Darley consults and trains first responders who have the challenge of providing 24/7 services in high-risk situations. She was a leader of the Start School Later initiative in Seattle, which succeeded in improving school hours for over 50,000 students. 

“It’s a pleasure to work with Sleep Cycle to increase public knowledge and appreciation for all that sleep does for our health,” said Darley. “My hope in doing this work is to increase the motivation of Americans to prioritize their sleep and reap all the rewards of a good night’s rest.”
