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.
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.
