Aromatherapy diffusers diffuse essential oils and natural fragrances into a room. They’ve become wildly popular because they’re viewed as a self-care product: while there’s not much research that’s been done around the health benefits of essential oils, people’s individual beliefs in elevating themselves, their mindsets, and their overall health propel them to purchase them. Scent can also be an important external trigger for inspiration: when someone is in a room that smells nice, they may feel better about themselves and their physical wellness, and that mindset might motivate them to do more.
