Why do snakes hide in caves in winter?

1. Snakes actually hibernate when hiding in caves in winter, because snakes are cold-blooded, and their blood and skin can't keep their bodies warm at all. The temperature is low in winter. If they don't hibernate, they will freeze to death.

Snakes hiding in caves and hibernating can help them spend the cold winter. In winter, there is little food, so snakes don't go out for activities, which can reduce energy consumption and maintain life even if they don't eat.
