The need for increased ventilation to improve indoor air quality has been much discussed in the media but humidity’s impact on the health of building occupants is much less understood. In this 10-minute interview, Mr Marshall-George gives a summary of the main effects low humidity has on the transmission of viruses, such as the flu and Covid, what we can do about it and the practicalities of improving indoor humidity levels on a nationwide scale.

Mr Marshall-George commented: “The invisibility of humidity to our senses has led to a lack of general understanding about the role it plays in maintaining a healthy indoor environment. We can’t see it. We can’t feel it. But low indoor humidity is a significant factor in the rise and fall of seasonal respiratory illness every winter. There is, however, something we can do about this. In this short podcast, I try to clearly explain the importance indoor humidity has on mitigating the spread of airborne viruses and how we can better manage our indoor humidity for the health of the nation.”
