You can choose from reed diffusers and electric diffusers. Electric diffusers have many benefits, including their enhanced functionality.
With electric aromatherapy diffusers, you may be able to control the level of fragrance that is released as well as setting a timer so that the fragrance is released at a specific time.
If you do have trouble sleeping, there are lots of essential oils for sleep that you can use.
Some electric diffusers also have a timer which you can set so that it is not running all night.
