For a relaxing nighttime routine, try adding sleep-inducing essential oils to a hot bath. To do this, you must first dilute the essential oils in a carrier oil such as coconut, jojoba, grape seed, or argan oil. Add about five to 20 drops of essential oil to each tablespoon of carrier oil. Add the oil mixture to the hot water before going into the bath. Adding the oil at the end ensures that the flavors don’t evaporate too quickly. You can also use the essential oil and carrier oil mixture as a massage oil directly on the skin. Remember that you should never apply essential oil directly to your skin without first diluting it with a carrier oil, as this can cause burns and irritation to the skin.
