I still have a handful of favourite scented candles, but I actually prefer using an essential oil diffuser. They're incredibly versatile — you can easily create your own custom blends by mixing your favourite essential oils and can program them to work for an hour or six hours, depending on your needs. The cool mist makes any room smell incredible and also adds a touch of humidity, which can help everything from respiratory issues to dry skin. I add lavender essential oil to my diffuser every night before bed and it helps lull me to sleep.
