AYO Wearable
-
A typical AYO session is 20 minutes. AYO was designed in a way that it seamlessly fits with your lifestyle, allowing you to continue with your daily routine while wearing it (e.g. cooking, working on the laptop, brushing your teeth, etc.) -
No, you need to wear AYO with open eyes for the light to be effective. -
AYO emits blue-turquoise light of approximately 470 nm. AYO’s irradiance levels (i.e. light strength) are up to 250 µW/cm² and can be considered as an equivalent to 10,000 lux of bright light emitted by a typical light box. -
AYO’s light has been rigorously tested and certified as safe for the eyes. It meets the highest standards for photobiological safety, as verified by the globally recognized independent certification body TÜV Rheinland, in compliance with the EU photobiological safety standard IEC 62471.
AYO is classified under the “exempt” group for photobiological risk.
In addition, AYO has successfully passed further eye-safety certifications including:
ANSI Z80.36
ISO 15004-2
-
As with any light therapy device, certain adverse reactions — such as discomfort, headache, dry mouth, eye strain, nausea, or hyperactivity — may occur on rare occasions. These effects are typically mild and short-lived, especially if you reduce the light intensity, shorten the session duration, or use AYO in a well-lit environment.
If you have any questions or concerns, feel free to reach out to us at info@goayo.com — we’d be happy to assist you. -
No, you do not need to use a smartphone or install the AYO app in order to use AYO. -
No, AYO is a consumer wellness device, which is not intended to diagnose, cure, or treat any medical condition.
Science & Results
-
AYO is based on light therapy and the science of Chronobiology.
Light therapy is a widely used and recognized method for improving mood, energy levels, and sleep quality, supported by thousands of peer-reviewed studies.Additionally, AYO is participating in clinical studies with leading institutions worldwide. Two of them — with the US Department of Defense and the University of Reykjavik — are already published and have shown AYO to be effective in decreasing sleep problems, improving sleep quality, and increasing performance.
You can learn more about the science behind AYO on our Science page.
-
Some customers report experiencing positive effects on their energy levels and mood after just one session with AYO.
Others need several days to a few weeks to feel lasting changes in sleep quality and circadian rhythm.
We recommend daily usage for at least 3 weeks to start feeling the desired effects. -
Typically, the optimal time to use AYO is in the morning, to help reset your circadian rhythm.
However, the ideal timing can vary from person to person and depends on your lifestyle and goals.
The AYO app provides personalized guidance on when to use AYO, when to avoid light, and other helpful metrics. -
1. Immediately or shortly after an AYO session, your energy and alertness can increase. AYO mimics natural sunlight, suppressing the sleep hormone melatonin, helping you feel awake and refreshed.
2. By controlling melatonin production during the day, you can adjust your circadian rhythm to fit your lifestyle. AYO helps you adapt faster to new time zones, shift work, or early mornings.
3. Suppressing melatonin during the day also supports higher melatonin production at night, leading to better sleep quality.
-
Based on your circadian rhythm, desired goals, and lifestyle, the AYO app provides full guidance on how to use AYO effectively.
