Eating late-night snacks regularly can easily harm the stomach and is even a hidden culprit behind stomach cancer. "In fact, except for shift workers who need to replenish their energy, most people don't need to eat late-night snacks. Even for those who need a late-night snack for energy, attention should be paid to the choice of snack types; it is best to opt for soft, easily digestible, and light options."
The "Huangdi Neijing" (The Yellow Emperor's Inner Canon) states: "When the stomach is not harmonious, sleep is not peaceful." Many people, especially children, toss and turn, grind their teeth, talk in their sleep, or drool at night, which is often related to eating too much in the evening.
