冬眠

冬眠 refers to the state of inactivity and reduced metabolism that some animals enter during winter to conserve energy. It is a natural survival strategy used by animals in cold climates when food is scarce.

The character 冬 means 'winter,' and 眠 means 'to sleep.' Together, they literally translate to 'winter sleep,' which accurately describes the concept of hibernation. This compound word reflects the seasonal nature of the behavior.

冬眠 is commonly used in biological and zoological contexts. In Chinese culture, it is often associated with animals like bears, squirrels, and bats. Understanding 冬眠 helps learners grasp how animals adapt to environmental changes, and it is a useful term for students studying biology or nature-related topics.
