In November, we started with recruiting new participants for the study on the effects of near-infrared light. Purpose was to include 20 more subjects in winter. The task was to include them all within 3 weeks to be ready before Christmas. And yes! We are happy to announce that we managed to find 20 enthusiastic compliant subjects. They are collecting a lot of new data for us. We are managing the project with the excellent help of Marthe Koopmans, who does her master internship with us. We hope to be able to publish the results next year! For now, we thank you for your interest, but we do not need more subjects.
