Doctors warn of danger of 'feather duvet lung'

Medical team say people's unexplained breathlessness could be down to bedding dust

As winter approaches it might be tempting to curl up under a thick feather duvet, but experts have warned it might lead to more than just warm toes.

Doctors have reported a case of "feather duvet lung" - a lung inflammation caused by breathing in dust from the feathers in bedding - and have called for medical professionals to be on the alert if patients turn up with unexplained breathlessness.
