But it isn’t just students who would benefit from a later start. Kelley says the working day should be more linked to our natural rhythms. Describing the average sleep loss per night for different age groups, he says: “Between 14 and 24, people lose more than two hours. For people aged between 24 and about 30 or 35, they lose about an hour and a half. That can continue up until you’re about 55 when it’s in balance again. The 10-year-old and 55-year-old wake and sleep naturally at the same time.”
Starting in adolescence, how does a person’s average sleep loss per night change as they age, according to Kelley?
It decreases as they age, balancing around when they reach the age of 55 It increases as they age until they reach the age of 55 It continually adjusts to the hours of their working day until they reach the age of 55 It highly depends on the individual
