Have you ever felt sleepy after eating a big meal? This feeling is commonly known as a food coma. A true coma is a state where a person becomes unconscious for a long period of time. However, a food coma is a much less serious condition because it isn’t dangerous or long-lasting. Scientists have studied the food coma to understand how it works. One explanation is that when we eat a lot of food, our blood flow is directed to our stomach to help digest the food.
你曾在吃了一顿大餐后感到昏昏欲睡吗？这种感觉通常被称为食物昏迷。真正的昏迷是指某人长期处于无意识的状态。然而，食物昏迷是轻微许多的状况，因为它不危险也不会持续很久。科学家研究了食物昏迷以了解它是如何发生的。其中一种解释是当我们吃下许多食物时，我们的血液会被引导到胃部来帮忙消化食物。
