Many people love using the scent of essential oils like lavender to help them fall asleep. Adding a couple of drops to the edge of your pillow before bed can help if you don't have a diffuser to hand, as it allows for easy inhalation with minimal effort. Alternatively, you can place the oil onto cotton balls and place on the inside of the pillow. This is also a great choice for other pillows and cushions around your home if you like to keep your furnishings smelling fresh.
