Waking Up Early Linked With Higher Anorexia Nervosa Risk: Study

In a society that often glorifies the benefits of waking up early, a recent study has shed light on a potential downside to this seemingly healthy habit. The research, led by investigators from Massachusetts General Hospital (MGH), suggests that waking up early may increase the risk of developing anorexia nervosa, an eating disorder characterised by underweight, diet restriction and a fear of gaining weight.

The study found a strong correlation between anorexia nervosa and early morning awakening, adding a new dimension to the understanding of eating disorders. Previous research had hinted at a connection between eating disorders and the body’s internal clock, also known as the circadian clock, which regulates sleep and various bodily functions.

The international research team delved into the genetic aspect of anorexia nervosa and discovered a noteworthy link between the genes associated with this eating disorder and those responsible for early morning awakening and going to bed early at night. This genetic risk assessment for anorexia nervosa was also found to be closely associated with an increased risk of insomnia.

Anorexia nervosa, which currently has a 58 per cent cure rate with available treatments, remains a challenging disorder to understand and treat effectively. The disorder has the second-highest mortality rate among mental health-related deaths, highlighting the urgency for further research to identify prevention and treatment strategies.

The findings from this study challenge the conventional narrative of the benefits of waking up early and emphasise the importance of considering individual differences in sleep patterns. While waking up early has been associated with increased freshness and productivity, it’s crucial to acknowledge that these habits might not be universally beneficial.

Understanding the complex interplay between genetics, circadian rhythms and mental health is a crucial step towards developing more targeted interventions for disorders like anorexia nervosa. As researchers continue to explore the multifaceted nature of eating disorders, this study opens new avenues for investigating the intricate relationship between sleep patterns and mental well-being.
