"Morning Person Traits Linked to Increased Anorexia Risk, Studies Suggest"

A study published in JAMA Network Open by researchers from Massachusetts General Hospital and other institutions has discovered a genetic association between anorexia nervosa and being an early riser, as well as a link to higher insomnia risk. This contrasts with other psychiatric disorders that are typically evening-based. The findings suggest potential new directions for anorexia nervosa prevention and treatment, focusing on circadian-based therapies, although the clinical implications require further research.

"New Study Reveals Surprising Insignificance of Light Color on Circadian Rhythms"

A study by researchers, including Dr. Christine Blume from the University of Basel and Professor Manuel Spitschan from the Technical University of Munich, has found that the color of light does not significantly affect the human internal clock or sleep patterns. The study involved exposing participants to different colors of light and measuring various sleep-related parameters. The results suggest that while light-sensitive ganglion cells are crucial for regulating the internal clock, the color of light, as perceived through cones, plays a minor role. This challenges the common belief that the blue light from screens is disruptive to sleep, indicating that the effect is more about the light's intensity and less about its color. The findings have implications for the design of lighting and electronic devices to support healthy sleep patterns. The study was published in the journal Nature Human Behavior.
