Highlights:

The body's internal clock, known as the circadian rhythm, deeply influences various aspects of human physiology, including sleep patterns and body temperature cycles. A recent study has spotlighted a notable interconnection between circadian rhythms and certain mental health conditions.


The new research conducted by Massachusetts General Hospital, reveals a correlation between anorexia nervosa and being an early riser, and vice-versa. It also found a connection between anorexia nervosa and insomnia (1).

Anorexia & Sleep Patterns: Unveiling the Genetic Link

Anorexia nervosa, a severe eating disorder characterized by restricted food intake and fear of gaining weight, carries one of the highest mortality rates among psychiatric illnesses.

Previous studies hinted at a possible link between eating disorders and the body's internal clock, which regulates sleep and impacts numerous bodily functions. To delve deeper into this relationship, researchers examined genes associated with anorexia nervosa, the body's internal clock, and various sleep traits, including insomnia.

The study employed Mendelian Randomization, a statistical method, to explore how genes linked to anorexia nervosa might influence other related traits. By analyzing the sleep patterns of individuals with genetic predispositions to anorexia nervosa, the study provided compelling evidence of the connection between this eating disorder and sleep behaviors.
