A normal man spends approximately 1/3rd part of his life span in sleep. A person usually sleeps about 8 hours in a 24hour period,
with a range of 4 to 10 hours per day, though newborns and youngsters sleep more and the elderly sleep less.1
Short and long
sleepers are equally at an elevated risk of death from any cause, according to researchers. Sleeping too much or too little, or keeping
a constant vigil, is like a night of ruin, robbing you of happiness and longevity.
