Instead of giving you some scientific reason about why we need sleep, I'm just going to keep it simple:
We no sleep, we go cray.
Without sleep, we start seeing things. We just get tired and then we pass out. It's as simple as that.
nocturnal animals sleep at daytime and daytime animals sleep at nighttime or for short nocturnal animals are the opposite of humans!!
they sleep at daytime and are playing at nightime. They are usaly not seen.
Non-nocturnal? Diurnal - awake during the day/sleep at night
daytime
Animals that are nocturnal, such as owls, bats, and possums, typically sleep during the daytime. These animals have adapted to be more active at night when it is cooler and there is less competition for resources. Some diurnal animals, like cats and dogs, also take short naps throughout the day.
Ferrets sleep all day because they are 'DIURNAL' animals. Diurnal animals are animals which sleep throughout the day and are active and also eat there food at night. However humans are 'NOCTURNAL' because they sleep at night and are active and eat during daytime.
They are not strictly nocturnal or diurnal, but are more active in the daytime.
All animals live in the daytime. Those that are active are called diurnal animals.
They didn't sleep in the day, they worked.
They are daytime animals.
