Elite football imposes intense physical and psychological demands, with congested schedules, late-evening fixtures, artificial lighting, and long-haul travel restricting recovery opportunities. These factors disrupt circadian rhythms, impairing sleep quality and quantity, suppressing melatonin, elevating cortisol, and delaying physiological restoration. The consequences extend beyond immediate performance deficits to increased injury risk, emotional instability, and long-term health concerns similar to those observed in shift-working populations. Youth and female players are particularly vulnerable due to developmental and hormonal sensitivities to circadian misalignment. This narrative review synthesises interdisciplinary evidence on how disrupted circadian timing affects athlete health, performance stability, and recovery capacity, and evaluates structural contributors, including scheduling, lighting, travel, and facility design. Addressing these challenges requires systemic reforms rather than isolated individual countermeasures. Architectural and environmental strategies offer practical opportunities to mitigate disruption. Complementary policy measures, including earlier kick-off times, mandated recovery periods following long-haul travel, and governance frameworks that integrate circadian health, are similarly crucial. Aligning scheduling, infrastructure, and organisational practices with human biological rhythms can protect athlete welfare, improve spectator well-being, and reduce environmental impact. Integrating circadian science into the operational and architectural fabric of football represents a medical, organisational, and sustainability imperative, supporting the long-term resilience and legitimacy of football.
