New guidelines for a good night sleep

Many older Australians spend more time in bed than they need to, according to sleep experts who are now armed with the first-ever science-based guidelines for sleep length.

The National Sleep Foundation, America's leading authority on sleep, has published its inaugural age-specific recommended sleep durations based on a rigorous, systematic review of the world scientific literature.

The new sleep code, based on a review of 312 studies from the last decade, has been adopted by Australia's national sleep health advocate, the Sleep Health Foundation.
