How can I effectively mix essential oils with water for a DIY aromatherapy spray?

To effectively mix essential oils with water for a DIY aromatherapy spray, start by choosing your desired essential oils and diluting them in a carrier oil like jojoba or almond oil. Then, add a few drops of the diluted essential oils to distilled water in a spray bottle. Shake well before each use to ensure the oils are evenly distributed in the water.
