Good sleep is incredibly important to health. It’s just as important as eating healthy and getting plenty of exercise. Unfortunately, our Western lifestyle disrupts the natural sleep rhythm. We sleep less today than in the past and the quality of sleep has also declined. Artificial light has stretched the day and taken regularity out of the waking / sleeping rhythm.


The rhythm and the successive blocks of time with which we may or may not perceive blue light is the key to good sleep. This rhythm can be adjusted by applying 30 minutes of blue light (daylight) in the morning and filtering blue light in the evening. Of course there can be other reasons for poor sleep. When a good sleep / wake rhythm cannot be achieved with light therapy, the cause is often much deeper on a medical or psychological level. Light therapy helps to achieve a good sleep / wake rhythm and determine whether the cause lies elsewhere.

Propeaq light therapy is based on scientific studies in which the conditions for optimal performance and sleep have become clear. We have translated these insights into patents that have been incorporated into our products. Our involvement in research is in our DNA. For example, we are researching post-operative recovery during surgical procedures with Zimmer Biomet, and Leiderdorp Hospital. Together with the VU Medical Center, Amsterdam, Propeaq is conducting research into postoperative delirium in the elderly in the emergency room.


Recently published studies have shown that light therapy can potentially be useful in several debilitating chronic diseases such as Parkinson’s disease, which are notorious for negatively affecting sleep in patients. For the most part, sleep medications are used to help with sleep, but side effects can be extremely troublesome for patients who already have cognitive and neurological impairments. Parkinson’s patients respond poorly to sleep aids because of daytime sleepiness, memory loss and additional risk of falling. Therefore, light therapy was first tested in patients with Alzheimer’s disease and dementia, and then in Parkinson’s patients. With very positive results. The Propeaq light therapy glasses are the latest innovation in light therapy with a number of clear advantages over traditional light boxes.
