Why Use Essential Oils at Night? 

Essential oils and aromatherapy are a great way to improve the quality of your sleep, and to establish good sleep hygiene routines to help you fall asleep faster. Studies show that olfactory exposure (smelling) of certain essential oils can act as a mild sedative and help induce sleep. Lavender in particular has been shown to help with relaxation and relief from stress and anxiety. 

Why Use a Diffuser for Sleeping?

Essential oil diffusers are a safe, effective way to get the benefits of aromatherapy while you snooze. They release the fragrance from the essential oils into the room by binding to molecules in the air. All it takes is a few drops of essential oils to get the benefits of aromatherapy while you sleep. 

Adding an essential oil diffuser to your bedroom and using it as part of your bedtime routine can help you sleep better. We’ve found the 8 best oil diffusers for sleep that come with added benefits like humidifiers, relaxing noise machines, and calming light.
