00:00How many hours do we sleep in a lifetime?
00:02To estimate the total time spent sleeping,
00:04scientists base it on the average lifespan and the average hours of sleep per night.
00:10Currently, French people sleep an average of 7 hours and 47 minutes per night.
00:15If we consider an average lifespan of 80 years,
00:18this represents about a third of our existence spent in the arms of Morpheus,
00:23that is, between 25 and 27 years of sleep.
00:26To obtain this figure,
00:27it is enough to multiply the average length of sleep by the number of days in a year,
00:32then to divide by 24 to convert to days,
00:35and finally by 365 to get the result in years.
00:39This calculation shows how much sleep occupies a predominant place in our life.
