Sleep Loss Disrupts Appetite Hormones, Increasing Hunger and Decreasing Fullness

Sleep deprivation, particularly from late-night activities like watching football matches, significantly alters the body's appetite-regulating hormones. This hormonal imbalance leads to increased feelings of hunger and a diminished sense of fullness, contributing to unhealthy eating habits. The disruption affects key hormones: leptin, which signals satiety, decreases, while ghrelin, the hormone that stimulates hunger, increases.
Hormonal Shift Towards Increased Hunger

The physiological response to insufficient sleep involves a direct impact on appetite hormones. Specifically, levels of leptin, the hormone responsible for signalling to the brain that the body is full, are reduced. Concurrently, ghrelin, often referred to as the "hunger hormone," experiences a rise. This dual hormonal shift creates a physiological state where individuals feel hungrier and less satisfied after eating, a phenomenon noted in the context of late-night football viewing.
Contribution to Post-Match Eating Compulsions

This hormonal rewiring is identified as a primary driver behind the strong urge to consume food, such as during post-match visits to mamak stalls. The combined effect of lower leptin and higher ghrelin levels makes the desire for food feel less like a conscious choice and more like an involuntary compulsion. This occurs even when the body may not require additional caloric intake, highlighting the powerful influence of sleep on metabolic regulation.
Broader Health Implications Beyond Appetite

Beyond the immediate effects on appetite, the disruption of sleep, as experienced during extended periods of watching football tournaments, has wider health consequences. Prof Dr Ahmad Izuanuddin Ismail, President of the Sleep Disorder Society of Malaysia, notes that even a single night of lost sleep can impair attention, reaction time, and decision-making. Furthermore, it can elevate blood pressure, promote inflammation, and negatively impact glucose metabolism, temporarily increasing cardiovascular risk, especially for individuals with pre-existing conditions like obesity or hypertension.
