The Express leads with research suggesting that an hour’s snooze after lunch is good for your health. American scientists believe it can prevent your brain from ageing and help you perform better in memory tests.
They examined 3,000 adults over the age of 65 and found that those who slept in the afternoon were better able to solve simple maths problems and memorise words – and those who didn’t, performed badly.
But the paper warns that the nap has to be for 60 minutes. A longer or shorter siesta won’t have the same effect.
