What lavender is

Lavender is a flowering herb whose scent has been associated with relaxation for centuries. In sleep research it's most often studied as aromatherapy — inhaling its essential oil — rather than as something you ingest.

What the evidence says

Several small studies suggest lavender aromatherapy may modestly improve subjective sleep quality and reduce anxiety, possibly by influencing the parasympathetic 'rest-and-digest' nervous system. Effects tend to be gentle, and much of the benefit may come from the ritual and relaxation cue it provides. It's low-risk, which makes it an easy addition to a wind-down routine.

How people use it

Common approaches include a few drops of essential oil in a diffuser, a pillow mist, or a warm lavender-scented bath before bed. If you have sensitive skin, avoid applying undiluted essential oil directly, and keep essential oils away from pets, some of which are sensitive to them.

Lavender: FAQ

The evidence suggests a modest benefit, mostly for subjective sleep quality and relaxation via aromatherapy. It's gentle and low-risk, and works best as part of a consistent wind-down routine rather than as a standalone fix.
