A sleep expert has advised people to take regular daytime naps in a bid to improve their brain health, and has also revealed the sweet spot length needed.
It's expected that babies and young children will take naps throughout the day, but it's not something that many adults will factor into their working day.
Now a team of scientists has discovered that those who nap could well be slowing the process of brain ageing by between three and six years, helping to "reduce brain shrinkage".
