Forget flannel pyjamas and slinky nighties – wearing nothing at all in bed could boost your health, one doctor says.

One in three adults sleeps in the nude, according to an international study by the U.S. National Sleep Foundation.

And now, Dr Sarah Brewer, a GP and nutritionist based in Guernsey, says it's been shown to have all sorts of benefits.

'Sleeping naked can regulate your temperature, helping you get the best night sleep,' she told MailOnline.

This is because people tend to fall asleep more quickly, and have better quality sleep, when the temperature is lower, she said.

And ditching pyjamas could be one way of preventing overheating in bed, which can exaggerate pre-existing skin problems

Women who sleep naked are less likely to suffer from yeast infections, Dr Brewer added.

Men who go commando in between the sheets are not as prone fungal infections in their groin – also known as the Jock Strap Itch.
