Circadian Health for everyone!
95% of the world’s population experiences health problems and 60% has difficulties with sleep*.

Half Measures

Generic solutions and sleep/health trackers gather information on how you are doing, rather than help you get where you want to be.

Overlooking Fundamentals

Your body’s biological foundation, the circadian rhythm, is overlooked. Yet, it is the key mechanism behind your sleep and health results.

AYO is Different

Your best sleep and health results start with you. AYO helps you use your own biology to achieve your goals.

*According to The Lancet and the National Sleep Foundation.

Understanding and supporting your circadian rhythm gives results

Numerous clinical studies and over 20 years of Chronobiology and Light Therapy research performed in leading institutions, including Harvard, Oxford and NASA, have shown that we can actively support our circadian rhythm in order to obtain healthier, happier and more active lives. These disciplines and insights are the cornerstone of Circadian Health.

Chronobiology is the study of biological rhythms, variations of the timing and duration of biological activity in living organisms. At the center of chronobiology research is the circadian rhythm and the human 24-hour circadian clock located in the suprachiasmatic nucleus (SCN) in the brain. This biological clock controls most of the brain and body functions including sleep, energy, mood, performance, metabolism, and the immune system. AYO is working on translating chronobiology clinical research into practical applications.

Light therapy, also known as phototherapy, is a treatment in which you’re exposed to a special artificial light source. While it might sound like a wellness fad, it is a widely-used and recognized method backed by thousands of peer-reviewed articles and studies. The clinical consensus is that blue light treatment is generally safe and effective in resetting the human circadian rhythm with numerous health benefits. AYO is an innovation leader in personalized blue light therapy.
