(File:Candle Diffuser.jpg - Wikimedia Commons) Aromatic inhalation involves breathing in the volatile scent of essential oils through the respiratory tract to exert physiological or psychological effects. This can be done using various tools to disperse the oil into the air, such as using a '''diffuser''' (aroma diffuser) to atomize the oil, burning an '''aromatherapy candle''' where the oil volatilizes with the heat, or applying drops to an '''aroma patch'''/'''essential oil necklace''' for slow release. In home environments, electric water-based diffusers or candle diffusers are often used to heat a container of water and essential oil, filling the room with aromatic mist. Inhalation can be '''indirect''' (like diffusing scent in a room) or '''direct''' (placing 1 drop of oil on a tissue and sniffing it under the nose). Via the olfactory pathway, essential oil molecules stimulate olfactory receptors in the nasal mucosa, sending signals to the brain's limbic system, thus influencing emotions, memory, and other psychological activities. They can also enter the bloodstream via the lungs to exert effects on bodily functions. Aromatic inhalation is fast-acting and one of the simplest and most common ways to use essential oils. For example, diffusing lavender essential oil in the bedroom before sleep helps create a relaxing atmosphere conducive to sleep; inhaling the scent of sweet orange or bergamot oil during times of stress can alleviate anxiety.
