Our latest study! Published in Nature Mental Health today, we show that bright days and dark nights are of fundamental importance for mental health. Individual light exposure data from >85,000 people…14 million hours of light data. Epic! Led by Angus Burns with

Spectrawear (our open-source wearable a-opic light dosimeter) has been in action to reveal associations between personal light exposure and subjective daytime sleepiness + the timing of night-time sleep in everyday life pnas.org/doi/10.1073/pn…

In this secondary analysis, we examined the (dis)concordance between subjective and objective #sleep in #depressed patients with #eveningness; and their change with #brightlight treatment. Steven WH Chau Hongliang Feng doi.org/10.1016/j.slee…

Congratulations to Salina who conducted this study to validate the use of BRIAN in both healthy controls (HC) and patients with non-seasonal #depression. BRIAN score did not differ from HC in the remitted patients but remained high in the non-remitted. tandfonline.com/doi/full/10.10…

Check out our new paper reporting age-related differences in the pupillary light response between children and adolescents! Ray P. Najjar Full article: jphysiolanthropol.biomedcentral.com/articles/10.11…

We are very happy that our work on the post-illumination pupillary response #PIPR is published! A more attenuated PIPR is associated with the age-related changes in circadian rhythms, such as reduced actigraphic Mesor and amplitude. neil roecklein doi.org/10.1093/sleep/…
