Why do sheep stay still in the rain when it rains?

Sheep standing still in the rain is actually their way of sheltering from the rain. Because there are scales and grease on the surface of wool, standing still can let the rain flow down and reduce the area that can get wet. If there is not much rain, only the outer wool of the standing sheep will get wet, while the thick inner wool is actually dry, which can keep the sheep warm. But if the rain runs away, it will be easier for the rain to enter the cracks in the wool. If it rains too hard, the wool will absorb too much water, and the sheep will be forced to sit there in a daze. There are scales and grease on the surface of wool, so standing still can let the rain flow down and reduce its wet area.

If there is not much rain, only the outer wool of the standing sheep is wet, while the thick inner wool is actually dry, which can keep the sheep warm. If it rains heavily, wool will absorb too much water and they will be forced to sit there in a daze. And not just sheep. Many animals have greasy hair surfaces and will not get wet.

For example, when bathing a cat or dog, don't get wet with water at once, but wash it hard and remove it from the fur. This makes it easier to clean many animals, such as cows, horses and camels, and stand or lie still in rainy days until the rain stops. (After all, there is no other way. After the rain stops, camels usually stand up and shake themselves. Sometimes the rain on the grassland will not stop, and herders will take camel jitter as a "forecast" for the weather to turn fine. Nature is not afraid that there is no life in the deep sea, but human science and technology are limited and have not all been found.
