University of South Australia:

More sleep could offset children’s excess indulgence over the school holidays as new research from the University of South Australia shows that the same decline in body mass index may be achieved by either extra sleep or extra exercise.

The striking new finding is part of a study that shows how children can achieve equivalent physical and mental health benefits by choosing different activity trade-offs across the 24-hour day.

Conducted in partnership with the Murdoch Children’s Research Institute, and supported by the National Heart Foundation of Australia, the team examined the optimal balance between children’s physical activity, sleep, and sedentary time across the 24-hour day to better inform tailored lifestyle choices.

On a minute-for-minute basis, moderate-to-vigorous physical exercise was shown to be 2-6 times more potent than sleep or sedentary time
