Standing vs. Lying Down. It's a common misconception that cows don't lie down to rest and that they sleep standing up, just like horses do much of the time. In fact, cows actually lie down for up to 14 hours per day, standing up every few hours, stretching and then lying back down again.
Each person is different depending on their age but in general, healthy adults need around 7 hours of sleep per night, with children and older people needing more. Teens typically need nine or more hour per evening, with younger children needing ten to fifteen hours for restoration.
