What is the petition about?
It is proven, that 40-60%RH is the optimal level for our respiratory immune system, and will reduce the spread of seasonal respiratory illnesses and their burden on society. Dr. Stephanie Taylor is calling on the World Health Organization to review the scientific evidence on humidity and health, and recommends a minimum lower limit of indoor humidity in public buildings to reduce respiratory infections.
