The Sleep Duration Linked To Slower Ageing In A Huge Study

Researchers generally found a “U-shaped” association.

Good-quality sleep has been linked to a longer life, slower biological ageing, and even a decreased dementia risk.

But what exactly counts as healthy sleep to begin with?

We know that frequent, unintentional daytime napping may be a sign of dementia-related brain changes, while going to bed after 1am might not be the best way to “age healthily” (even if you’re naturally a night owl).

And now, a study published in Nature has identified the sleep duration that appears to be associated with “biological age gaps”.

What is a “biological age gap”?

Our chronological age is easy to calculate – this just means how long we’ve been alive.

But our biological age, which measures our wear and tear on a........
