No longer solely celebrated as a time machine to breakfast, a good night’s sleep is now heralded as the ultimate wellness win. It makes sense; sleep plays a massive role in your physical and cognitive health, not to mention your skin’s appearance. And seeing as we’re all extremely committed to vitality (and a megawatt glow), we’re also equally as devoted to ensuring our eight hours are as blissful and beneficial as possible. Sight and sound aren’t the only senses that affect your sleep, though – smell plays a part as well. Yep, even if you’re following the evening ritual rules by limiting light and nixing noise, you can still take your bedtime regime to the next level with the addition of a fragrance. In fact, some scents are scientifically proven to promote relaxation, improve sleep quality and even ease insomnia. But no, we’re not suggesting you try to drift off from within a heavy cloud of perfume or with a lit candle atop your bedside table (a definite fire hazard) – a diffuser is the perfect overnight option. It’ll evenly disperse scent, delicately fragrancing the space without disrupting your slumber. Here’s our edit of divine diffusers to help deliver the ultimate night’s sleep – you’ll be headed to a vanilla-scented dreamland in no time. Sleep tight.
