Scent & Sleep: How Aromatherapy Can Boost Your Brain—and Why COVID Made It Even More Essential

Michelle Reum | AUG 1, 2025

What if your nighttime ritual could do more than help you fall asleep?

What if it could actually nourish your nervous system, enhance your memory, and gently restore your sense of self—while you sleep?

A recent study suggests that simply diffusing essential oils during sleep may do exactly that. The scent we so often associate with comfort and mood may also be the very key to supporting our cognitive health. And through the lens of Ayurveda, this revelation feels less like news and more like a return to what we’ve always known: the body heals through the senses.

But for many, COVID interrupted that connection. The sense of smell—so central to memory, pleasure, and presence—suddenly disappeared.

What does it mean to live in a body without scent? And how can we gently invite it back?

Let’s explore the science—and how one of Ayurveda’s most sacred rituals, Abhyanga, can support this journey.


What the Science is Saying

In 2023, a study published in Frontiers in Neuroscience (PMID: 37554295) explored how essential oils used during sleep affect memory.

Participants, aged 60 to 85, were exposed to a different essential oil each night as they slept. A control group used only unscented water.

The results were profound.

  • Those who inhaled essential oils during sleep showed a 226% improvement in memory recall.

  • Brain scans revealed stronger connections in a region called the uncinate fasciculus, which links memory and emotional processing with decision-making.

In essence, gently breathing in plant-based aroma supported the brain’s structure and function—without pills, stimulation, or force. Just the subtle power of scent.


Why the Nose Holds So Much Power

The olfactory nerve, which governs our sense of smell, is the only cranial nerve that opens directly to the outside world. It connects immediately to the limbic system—the part of the brain that holds memory, emotion, and instinct.

This is why one deep inhale of lavender can quiet the heart. Why the scent of rose can evoke longing, or comfort. Why so many of us feel disoriented when scent disappears.

And that’s exactly what happened for many people who contracted COVID-19.

The virus didn’t necessarily destroy the smell-sensing nerves themselves—but it inflamed and disrupted the delicate cells that surround and support them. For some, this sense returned quickly. For others, it lingered. Or changed entirely.

For those on the path to healing—especially from stress, sensory disconnection, or long COVID—scent can be one of the most profound invitations home.


Abhyanga: Aromatherapy Through Touch

One of the most beautiful and powerful ways to reawaken the senses is through Abhyanga, the traditional Ayurvedic practice of warm oil massage.

Offered here at Mind Breath Bodywork, Abhyanga is a full-body experience that blends scent, touch, and intentional rhythm to restore balance on every level. This is not a clinical massage—it’s a nurturing ritual designed to soothe the nervous system and bring you back to your body.

Each session includes:

  • Herbal-infused oils, selected for your dosha and infused with therapeutic aromatics

  • Long, sweeping strokes to move lymph, calm Vata, and ground the mind

  • Aromatherapy woven throughout, reactivating the olfactory-limbic pathways

  • Quiet, intentional space to let your body shift from alert to ease

This is wellness in its most feminine form: slow, sensual, deeply restorative.


How Abhyanga Supports Sleep and Brain Health

This ritual goes beyond physical relaxation.

  • It nourishes and soothes the vagus nerve, helping you shift from stress into deep rest.

  • It hydrates and supports the tissues that become depleted through overwork, worry, or illness.

  • It calms overactive thoughts and allows the nervous system to feel held.

  • And most importantly, it reintroduces scent through touch—a profound method for reconnecting with the body after disconnection or loss.


A Ritual for the Woman Who’s Ready to Return to Herself

If you are feeling overstimulated, disconnected from your senses, or simply craving deeper rest, Abhyanga is a pathway back to wholeness.

You don’t need more effort.
You need a return to softness.
A return to your senses.
A return to your rhythm.

Book your session today and receive what your body has been quietly asking for: warmth, rhythm, presence, and peace.
