Almost all animals need to sleep to stay healthy. But sleeping can also be dangerous because other animals may hurt those who are sleeping. This leads to many different ways of sleeping that help them stay safe. Some of these ways may surprise you!

Almost all bats sleep upside down. They hang from a branch of a tree or the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away.

A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphin mothers and babies can go without sleep for as long as two months to stay safe.

Some ducks sleep with just half their brains, too. These ducks often sleep in a line. The ducks at both ends help to keep the group safe. They keep one eye open to watch for danger. The ducks in the middle sleep deeply with both eyes closed.

Seals breathe air, but that doesn’t stop some of them from sleeping underwater. They hold their breath and dive deep to sleep for up to twenty minutes at a time. Sleeping deep underwater helps these seals stay safe from animals that hunt them near the surface.

Horses often sleep standing up. Their legs lock in place so they don’t fall over. If a horse is lying down, it needs a long time to get up. A horse can run from danger more quickly if it is already standing.

A flamingo can sleep while standing on one leg. The standing leg locks so it stays straight. The other leg remains close to the flamingo’s body. Its head rests on its back. A flamingo lives (and sleeps) near many other birds to stay safe.

Some seabirds can sleep while they fly. These large birds spend most of their lives over the ocean. They are in danger on the water, but they are safe in the air. They fly for many hours without flapping（拍打）their wings. Sometimes they sleep while they are flying.

Dreams may be more important than sleep. Some people don’t need much sleep. But they all need to dream, scientists say.

Dreams take up about one quarter of our sleeping time. People have several dreams each night.

Dreams are like short films. They are usually in color. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.

Some people get new ideas about their work from dreams. They could have been thinking about their work all day. These thoughts can carry over into dreams.

Sometimes we wake up with a good feeling from a dream. But often we can’t remember the dream. Dreams can disappear quickly from memory.

Too many dreams can be harmful(有害的). The more we sleep, the longer we dream. The mind is hard at working when we dream. That is why we may have a long sleep and still feel tired after getting up.

Winter is cold and it can be difficult for animals to find food during winter. They get through winter in many ways.

Would you like to go to a warm place for the winter? That’s what migratory (迁徙的) animals do. When the weather starts to get cold, migratory animals like some birds and butterflies fly to a warmer place, and then they come back in spring.

Another good way to get through winter is to sleep through it. Many animals hide and sleep during the winter. Their body temperature drops and hearts beat more slowly. This helps them to save their energy. They do not eat. They live off their fat. They wake up when the weather gets warmer. We call this hibernation (冬眠). Snakes, frogs and bears hibernate in winter.

Many animals stay active in winter and adapt to (适应) the cold weather. Some animals save food in summer and autumn and eat it in winter. This is what squirrels do. Other animals make changes in their bodies or behavior (行为). To keep warm, some animals grow thicker coats in winter. Some animals eat different kinds of food as the seasons change. The red fox eats fruit and insects in the other three seasons, but eats small rodents (啮齿类动物) in winter. Other animals change colour. The arctic (北极的) fox is brown in summer. Its coat turns white in winter.

How do you live through the winter? Do you wear a thick coat? Do you stay inside? Or do you live in a warm place?
