airscenting

Airscenting refers to the intentional release of scented compounds into indoor or outdoor air to alter atmosphere, influence mood, or enhance perceived environment. The practice is used in homes, workplaces, and therapeutic settings. The term is not standardized in scientific literature.

Common methods include diffusion devices that emit fragrance, such as ultrasonic diffusers, nebulizing diffusers, and evaporative systems; scented products like candles and plug-ins; and, in some cases, natural processes of air exchange with scent-bearing plants or outdoor air.

Effects and applications vary. Olfactory cues can affect mood, arousal, and memory associations, while marketers use airscenting to establish ambiance or reinforce branding. Efficacy depends on scent strength, ventilation, individual sensitivity, and cultural associations, with adaptation reducing impact over time.

Safety considerations include allergy and asthma risk, irritation, and exposure to volatile compounds. Best practice emphasizes labeling, controlled concentrations, and adequate ventilation. Because standards are not universal, practices are guided by consumer preference and industry guidelines rather than formal regulation.

Etymology and usage: the term blends air and scent, and is most common in fragrance industry discourse and sensory research. Related concepts include scent marketing, olfactory environment, and indoor air quality.
