Feeling hungry after waking up from a nap can be attributed to several factors involving hormones and sleep quality. While you sleep, your hormone levels shift; for example, growth hormone, which increases during naps, signals the body to seek more energy intake through food for repair [2]. Additionally, inadequate sleep can elevate ghrelin, the hunger hormone, and lower levels of leptin, which suppresses appetite [1][2].

Moreover, low blood sugar levels, caused by factors like skipping meals or stress, can lead to increased feelings of hunger post-nap. As your body tries to stabilize blood sugar, it may send hunger signals even after a short sleep [2][4][6].
