Blue light and your biological clock

Top athletes strive for perfection and optimal performance. The secret lies in their biological clock. Using Propeaq light glasses in combination with Chrono Coaching helps athletes adapt to different time zones. This is crucial for top athletes, as it allows them to make the most of their valuable training time on site.

This not only improves performance, but also supports better sleep by regulating melatonin production. Thanks to the powerful blue light technology in the light therapy glasses, athletes can recover faster.

The power of Chrono Coaching

Do you perform best in the morning, but the competition is in the evening? Then Chrono Coaching can shift your peak moment. This is pure applied science.


Chrono Coaching improves performance by aligning athletes' biological clocks with their training and competition schedules. With Chrono Coaching, you learn when you need to be exposed to daylight and when you need to block light, which is essential for an optimal sleep-wake rhythm. This approach has been proven effective and is already used by hundreds of Olympic athletes to maximize their peak performance.

Wearable solutions for top athletes

For top athletes, Propeaq light glasses offer a portable solution to maximize their performance, even under challenging conditions. Simply by wearing the light glasses at the right time, you can experience the benefits of Chrono Coaching and improve your sleep quality. With this technology, achieving a well-balanced sleep-wake rhythm is within reach, which is crucial for achieving peak performance.

We consider it a tremendous honour to be able to help more than 1,500 top athletes improve their performance.

Hype of Hope: innovative blue light therapy for Parkinson's during RadboudUMC Parkinson Symposium

During the RadboudUMC Parkinson Symposium on May 16, 2025, Propeaq emphasized the promising results of a 2019 study into blue light therapy in Parkinson's patients. This study, published in the journal Hindawi Parkinson's Disease, showed that three quarters of the participants, after using the Propeaq light therapy glasses for at least a week, reported improvements in sleep, mood and motor functions. This non-invasive therapy appears to be able to significantly improve the quality of life of patients. The results of a new study are expected in the summer of 2025, which is expected to further substantiate the effectiveness and safety of the therapy, called Chrono Coaching.
