If you've scrolled through TikTok lately, you've likely seen the growing trend of sleep perfumes—fragrances designed to be worn to bed to promote relaxation and better sleep. But do they actually work? We asked experts to break down the science and the hype.
What Is Sleep Perfume?
Sleep perfumes are scents people use as part of their bedtime routine, either to relax or to improve sleep quality. While some are specifically marketed for sleep, many people use everyday fragrances that feel cozy, nostalgic, or fresh. "The nighttime fragrance should represent something softer, a quieter moment—something that smells like wrapping up in cozy blankets," says Kelly Kussman, founder of Cayla Gray. "You want it to last through the night without being overpowering when you lay your head down."
The Benefits: Scent as a Sleep Cue
According to experts, the real power of sleep perfume lies in its ability to create a mental association. "There are limited studies on scents like lavender or chamomile being calming, but the stronger effect is mental conditioning," explains Chrissy Lawler, certified pediatric sleep consultant and author of The Peaceful Sleeper. "If you use a specific scent before bed and have a great night's sleep, your brain starts to tie that scent to relaxation."
Both Kussman and Lawler emphasize that scent works best as part of a consistent nighttime ritual. Our sense of smell is strongly linked to memory, so a familiar fragrance can trigger a sense of calm and signal to your body that it's time to wind down. However, Lawler warns that sleep perfumes are not a quick fix for poor sleep habits. "If you've made all the mistakes with sleep hygiene and hope to dose yourself in lavender and sleep well, it's not going to work. And then that scent becomes a reminder of how much you're not sleeping," she says.
Best Scents for Sleep
When choosing a sleep perfume, experts recommend notes like lavender, eucalyptus, chamomile, and even vanilla for their calming properties. "I'd suggest staying more herbal than floral, but ultimately it's about what gives you that warm, releasing feeling in your chest," Lawler says. "The goal isn't to fix your sleep—it's to create a consistent cue that tells you it's okay to let the day go," Kussman adds.
