The wearable device leverages blue light and a dedicated app to support circadian rhythms to improve sleep quality, energy levels, and mood.


Summary: AYO, specializing in circadian light therapy, introduced its wearable device at SLEEP 2024. The device, worn like sunglasses, uses blue-turquoise light to help regulate circadian rhythms, aiming to improve sleep quality, mood, and overall wellness. AYO’s technology, backed by over 20 years of research and validated by clinical studies, integrates with the Circadian Health app for personalized health management. The device also combines circadian blue light with red light therapy to support visual health.

Key Takeaways:

  • Debut at SLEEP 2024: AYO showcased its wearable circadian health device at this year’s SLEEP 2024 show, highlighting its use of blue-turquoise light to improve sleep, mood, and overall wellness.
  • Scientifically Backed Technology: AYO’s device is based on over 20 years of research and has been validated in over 15 clinical studies with institutions like the US Department of Defense and Mt Sinai, showing improvements in sleep quality and performance.
  • Health Management: The device integrates with the Circadian Health app, providing personalized guidance on light exposure, meal and exercise timing, and sleep patterns.

AYO, a company specializing in circadian light therapy, made its debut at this year’s SLEEP 2024, showcasing its wearable device designed to enhance circadian health using blue light technology. 

Worn like sunglasses, the device uses specific wavelengths of blue-turquoise light (peaking at 470 nm) to help users regulate their circadian rhythms, potentially leading to better sleep, mood, and overall wellness.

“Unlike trackers or generic sleep/health solutions, AYO taps into your circadian rhythm—a biological foundation that impacts all essential brain and body functions such as metabolism, sleep, alertness, immune response, mood, and many more,” says Alex Dimitrov, co-founder and chief commercial officer of AYO. “By using your own biology and light therapy, AYO enables you to venture beyond tracking and actually improve your health and wellness outcomes.”

Health Management with the Circadian Health App

AYO pairs with the Circadian Health app, delivering personalized guidance on light exposure, meal and exercise timing, sleep dept, wake-up goals, and more. This integration aims to provide users with detailed circadian health management.  

AYO also combines circadian blue light with red light therapy to support visual health.

The AYO technology is based on over 20 years of research. AYO is scientifically validated, participating in over 15 clinical studies with institutions like the US Department of Defense, Memorial Sloan Kettering Cancer Center, and Mt Sinai. Two already completed studies have shown improvements in sleep quality and performance. Additionally, AYO is part of a major light therapy study by the University of Arizona, focusing on enhancing sleep and mental health.

AYO has received several accolades, including the Red Dot Award for product design and the SleepTech Award by the National Sleep Foundation.
