Do doctors recommend diffusers?
Johns hopkins also advises against using essential oil diffusers, small household appliances that create scented vapor. Diffusion in a public area or household with multiple members can affect people differently. For example, peppermint is often recommended for headaches. Avoid inhaling undiluted oils directly, as this can lead to irritation. Diffuser safely: if using a diffuser, follow the manufacturer’s instructions and ensure that the space is well ventilated. Prolonged exposure to high concentrations of essential oils is associated with negative heart issues and lung symptoms.
