It varies between breeds and individuals, but at least 10 hours a day, in my experience.
Adult: 6 hoursChild: 8-9 hours
8 hours is taken to be a good and agreed estimate.
8hrs is recommended for all humans
Sleep requirements vary with age. The average best sleep for a normal adult is seven and one-half to eight hours.
About 8 Hours Through The Night, 1-2 Hours During The Day.
For a kid about 8 - 10 hours of sleep is fine for an adult maybe a little less but it also depends on how tired you were that night hope I helped:) From ?
How many hours does it sleep
Sleep requirements are dependent mainly on age and activity level. A baby normally has around 12 to 14 hours sleep; a teenager (12- to 17-year-old) should have 9 to 10 hours; an adult can normally get away with 8 hours of sleep.Adults need 7-9 hours of sleep. If still tired they should sleep even more.normally eight hours
The amount of sleep one needs each night depends on various factors including age, gender, and sleep quality. The average amount for an adult is 7-8 hours.
they sleep for 10 hours a day they sleep for 10 hours a day
Atleast 7 to 8 hours of sound sleep is needed for an adult to lessen the work pressure. If that's not possible,6 to 7 hours of sleep is badly required, otherwise you will become lethargic during working hours.
There is no magic numbers, sleep differs for each person. But as a good rule of thumb: an average adult needs between 7.5 and 8 hours of sleep per night. But many people can function with 6 hours' sleep, and there also some who need 9 hours or more. The amount of sleep needed to function the next day varies from individual to individual, and is determined genetically and hereditarily.
