Forget fresh air – humidity may help prevent flu

Forget the advice that fresh air is healthy – a humid fug can protect against flu, according to new research.

Humid indoor conditions reduce the infectivity of the flu virus by more than five times, a study has shown.

Scientists tested flu infectivity using artificial dummies that can "cough" and "breathe".

Two of the mannequins, consisting of model heads connected to machinery, were used to simulate healthcare workers in an examination room.

The scientists, led by Dr John Noti, from the National Institute for Occupational Safety and Health in US, said raising indoor humidity "significantly" reduced the ability of flu to spread.
