Cost-saving energy hacks may be putting our health at risk, an expert has warned

Cost-saving energy hacks may be putting our health at risk, an expert has warned.

Millions of Britons are keeping their windows closed, turning the heating off and using log burners in a bid to save energy and keep bills down. 

But these actions increase exposure to pollutants — such as those from cooking or burning wood — according to Professor Catherine Noakes, a mechanical engineer at the University of Leeds.

A lack of ventilation also drives up the chance of spreading illnesses, such as Covid and flu, and raises the risk of damp and mould, which can trigger respiratory infection.

Professor Noakes, a member of SAGE who advised the Government on its pandemic response, told Britons to open their windows ‘intermittently’ and turn on extractor fans after showering and cooking to boost air turnover.

The cost-of-living crisis is seeing Brits avoid making their homes colder so they don’t need to turn the heating on — amid warnings average annual bills will double to £2,500.

With food, fuel and mortgage rates also soaring, many may be unwilling to run the risk of making their home colder.
