80-Minute Sleep Loss in Teens Exposed to “Forever Chemicals”

igher blood levels of four specific types of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," are linked to poorer sleep quality in young adults. These chemicals, found in everyday products and the environment, have been shown to disrupt genes responsible for regulating sleep and wake cycles, leading to decreased sleep duration and more sleep disturbances.

Environment and Hippocampal Size Impact Depression in Youth

Challenging social environments and the size of the left hippocampus in children aged 9-11 contribute to an increased risk of depression. Researchers found that children with larger hippocampal volumes are more sensitive to negative social environments, amplifying depressive symptoms over a two-year period.
