Have we ever thought about how many hours we actually sleep? With the advancement of technology, sleep deprivation has emerged as a major problem. While humans are researching to find sleep-promoting techniques, many animals happily spend more than 80% of their time sleeping every day.
There are animals such as giraffes that need only a few minutes of sleep a day, while, interestingly, dolphins and whales do not sleep for the first month of their lives and can switch between their left and right hemisphere of the brain to turn on/off altering it with the left or right eye while they sleep. But, some animals spend much of their entire lives in dreamland. Let us find out more about some of the sleepiest animals in the world!

Hamsters are rodents belonging to the subfamily Cricetinae.
