Can You Sleep With an Essential Oil Diffuser On?

It can be okay to diffuse essential oils while you sleep, but we recommend running a diffuser for a short period before bed or using a timer rather than assuming it is safe to leave on until morning. Overnight use depends on the device’s instructions, its shutoff features, where you place it, and whether anyone sharing the room is sensitive to the oil or mist.

Turn your diffuser off if its instructions do not permit unattended use, if it must be refilled during the night, or if its cord could be pulled, pinched, or exposed to water. You should also stop diffusing if the scent bothers you or causes coughing, a headache, or irritation; moving the diffuser farther away is not a substitute for turning it off when you feel unwell.

If children or pets share your room, take extra care to keep the device and oils out of reach, and ask a veterinarian before diffusing around pets because some essential oils may be harmful to them. Our Mini USB Aroma Humidifier & Essential Oil Diffuser with Soft LED Light should be used according to its specific setup and care directions; our team’s setup, safety, and care guide is a useful starting point before you decide whether to run it at bedtime.
