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.”
What does Kelley say about the relationship between working hours and natural rhythms?
The working day should be adjusted to our natural rhythms Our rhythms have to be adjusted to our working day This relation is in sync only once we reach the age of 30 or 35 They are in sync for most but not all people
