The sleep Foundation article examines how sleep deprivation can lead to increased calorie consumption by disrupting the balance of appetite-regulating hormones, specifically increasing ghrelin levels and decreasing leptin levels, which results in heightened hunger and potential overeating. Additionally, insufficient sleep affects insulin sensitivity, impairing the body's ability to regulate blood sugar levels, which can contribute to weight gain and elevate the risk of metabolic disorders. These physiological changes not only impact physical health but also influence brain health and cognitive performance, as metabolic imbalances can affect energy levels and cognitive functions. To support both brain and overall health, the article recommends prioritizing sufficient sleep to maintain hormonal balance and proper metabolic function. These insights are based on current scientific understanding of the interplay between sleep, metabolism, and cognitive health.
