After our successful light study in 2021 in which we demonstrated beneficial effects of near-infrared (NIR) light on well-being and health and published a paper about this (pdf), we are continuing with a follow-up study this year. This time we will also look at the mechanisms behind the effects of NIR light. The study is again sponsored by Seaborough and is in collaboration with the Chronobiology Department of the University of Groningen. Sign up now as a participant!
We are currently working hard to recruit 80 healthy participants who have sleepiness or mood symptoms. You must be willing to sit behind a lamp with near-infrared light for two weeks, five mornings per week. Amongst other things, mood, well-being, sleep quality and the immune system will be assessed. You will also be wearing a Fitbit smartwatch to measure certain effects. Upon completion and submission of all data, you will receive a compensation of 500 euros. Furthermore, after submitting complete data sets, where all instructions have been followed properly, you will receive a bonus payment of 200 euros.
Participants will be recruited in areas around Groningen, Zwolle, Amsterdam, Eindhoven, and province of Noord Holland. Both Dutch and English-speaking people are welcome, so if you are interested and have drowsiness or mood problems, send an email to firstname.lastname@example.org. You will then receive more information, a consent form and a link to the selection questionnaire. The first study period runs between February and March, so be quick! The sooner you apply, the sooner you can be scheduled in.
