How many hours does it sleep
The nouns are hours (plural) and sleep. The word he is a pronoun.
Snakes do not have eyelids and cannot close their eyes, so they do not have a traditional sleep pattern like mammals. Instead, they rest throughout the day and night, taking short periods of inactivity when needed.
adults are meant to have at least 8 hours of sleep and children are meant ot haveat least 10 hours of sleep
if you mean how many hours you should sleep in a year it would be 3,650 hours of sleep for a regular year not a leap year
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.
about 10 hours of sleep
you must get atleast 9 hours of sleep
I sleep about 7 to 9 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.
