深夜肚子咕咕叫的两难时刻：究竟该垫点吃的，还是硬扛到天亮？

Core Viewpoint - The article discusses the health implications of going to bed hungry and the effects of late-night snacking on sleep quality and overall health [5][6][9]. Group 1: Effects of Going to Bed Hungry - Going to bed hungry leads to an "energy crisis" in the body, causing low blood sugar levels that stimulate the sympathetic nervous system, resulting in increased heart rate and blood pressure, which negatively impacts sleep quality [6]. - Hunger increases cortisol secretion, a stress hormone that not only makes individuals feel hungrier the next day but also promotes fat accumulation, particularly in the abdominal area [6][7]. - This creates a vicious cycle: going to bed hungry leads to shallow sleep and waking up easily, resulting in fatigue and extreme hunger the next day, which can lead to binge eating and deteriorating health [7]. Group 2: Effects of Late-Night Snacking - Late-night snacks, especially those high in sugar and fat, provide immediate satisfaction but keep the digestive system active, significantly affecting deep sleep [9]. - Blood sugar fluctuations become more pronounced due to late-night eating, which can lead to further health issues [9]. - To balance health and sleep, it is recommended to consume light, easily digestible foods if hungry before bed, such as warm milk, unsweetened yogurt, a small bowl of oatmeal, half a banana, or a few almonds, ideally 1-2 hours before sleeping, with a caloric intake of 100-150 kcal [10].
