Electric fan use for cooling during hot weather: a biophysical modelling study
Published in: The Lancet Planetary Health
In hot weather, electric fans can potentially provide effective cooling for people, with lower greenhouse gas emissions and cost than air conditioning. However, international public health organisations regularly discourage fan use in temperatures higher than 35°C, despite little evidence. This study aimed to determine humidity-dependent temperature thresholds at which electric fans would become detrimental in different age groups.
