Sharper Mind, Better Sleep: The Science Behind Mandarin Essential Oil

We often turn to citrus oils to lift our spirits, but a new study suggests that mandarin essential oil does more than smell like sunshine. Research published in the journal Molecules found that mandarin oil may also enhance mental focus and improve sleep quality. 

In this controlled lab study, participants were exposed to mandarin essential oil through inhalation while undergoing brainwave (EEG) monitoring and attention-based tasks. The results were both intriguing and encouraging: participants showed increased alpha and beta brain activity, which is associated with alertness, mental clarity, and cognitive performance—especially during tasks that require sustained attention.

But here’s where it gets interesting: even while supporting concentration, mandarin oil also showed calming properties, helping ease the transition into restful sleep for those experiencing mild sleep disturbances. In other words, this citrusy scent seems to energise without overstimulating, making it a versatile addition to both focus routines and wind-down rituals.

Whether you’re heading into a busy workday or winding down after one, mandarin essential oil offers a gentle, balanced approach to mental well-being.
