What Is The Minimum Sleep Required By A Person?

Although this can vary from one person to another, some doctors consider four hours of sleep to be the minimum in order to function normally during the day and remain in a position to conduct work related tasks. Nevertheless, determining the minimum amount of sleep necessary is not a precise science, as this really depends on the individual in question. Getting only four hours of sleep for a prolonged period of time may, however, really wear down your system, leading to illness, general fatigue and other health problems.

Ideally, you should get a minimum of 7.5 hours of sleep every night, while getting 8 or even 9 is much preferable. The average Briton sleeps 8.1 hours each night, according to a UK-based survey. Nevertheless, some political leaders have boasted about how little sleep they get, yet how well they are able to function. Former British Prime Minister Margaret Thatcher, for example, claimed that while in office, she got by perfectly well on 5 hours of sleep.

The bottom line, however, is that you should try to sleep for about 7 to 8 hours each night, but that the "minimum" amount of sleep necessary depends on what kind of tasks you wish to perform during the day, and how your body works.

As per my elders suggestions, the minimum sleep required by a man is eight hours continuous sleep. But nowadays many people are more interested in other activities than sleep. But we will be very much more active, if we have a good sleep of 8 hours.
