Røyhet

Røyhet is a Norwegian term used to describe the presence, intensity, or character of smoke in air, or the smoky flavor of foods. In air quality discussions it denotes smoke comprising aerosols and gases produced by combustion, which can originate from tobacco use, wood fires, industrial processes, or wildfires. The term also applies to culinary contexts where foods acquire smokiness through smoking methods.

Health and environmental implications: Exposure to røyhet, especially from tobacco or wildfire smoke, can irritate the eyes and airways and has been linked to increased risks for respiratory and cardiovascular problems. Indoor røyhet is a major concern for public health; reducing exposure involves source control (no smoking indoors, burning fewer materials), increasing ventilation, and using filtration where appropriate. Outdoor smoky conditions from wildfires or industrial activity can affect air quality and visibility, depending on wind and atmospheric stability. Monitoring uses indicators such as particulate matter (PM2.5, PM10), carbon monoxide, and volatile organic compounds.

Culinary use: In cooking, røyhet is valued for flavor and aroma. Cold smoking and hot smoking are two main techniques; smoking materials include wood, charcoal, or pellets. The degree of røyhet varies with temperature, duration, and wood type, affecting texture and taste.

Regulation and culture: Many jurisdictions regulate smoking indoors; public health campaigns promote smoke-free environments. In cultural contexts, røyhet is sometimes celebrated in traditional smoked foods and in regional cuisines.
