Humidity and Health
The relationship between relative humidity and health problems as it relates to air borne pathogens. The ideal range for health is 50% RH and the target for your homes humidity level should be between 40 & 50%. The trick is balancing this without creating condensation, and potential mold, surfaces like windows. Ensuring your home is updated with sufficient insulation, door seals, newer windows making it energy efficient it will also keep the indoor surfaces warmer when it is cold outdoors and hence the higher we can raise the general relative humidity without causing too high relative humidity next to cold surfaces.
