Night Eating Syndrome (NES) is a complex eating disorder characterized by excessive food intake during the evening and night time, often linked to emotional distress, circadian rhythm disruptions, and poor dietary habits. This paper explores the causes and consequences of NES, with a specific focus on hydration, emotional eating, and dietary strategies as potential intervention approaches. Emotional eating, a common feature of NES, is influenced by stress, mood disorders, and psychological distress, leading individuals to consume food as a coping mechanism. Additionally, dehydration plays a crucial but often overlooked role in NES, as the body may misinterpret thirst as hunger, triggering late-night cravings and reinforcing unhealthy eating patterns. Poor hydration can also contribute to fatigue, irritability, and increased emotional eating, further exacerbating NES symptoms. Effective dietary strategies, including balanced meal timing, nutrient-dense food choices, and hydration-focused interventions, may help regulate hunger cues, stabilize mood, and improve circadian alignment. This review highlights the need for a holistic approach in managing NES, incorporating psychological, nutritional, and behavioural modifications to promote healthier eating patterns and overall well-being.
