Good Scents, Good Mood: The Science Behind Fragrance & Emotion

Good Scents, Good Mood: The Science Behind Fragrance & Emotion

It sounds, at first, like an unlikely pairing. But your emotional well-being and the air in your home are actually deeply connected.   

Research shows that scent is more closely tied to memory and emotion than any other sense. While images and words can (and do) trigger recollections, a familiar fragrance is able to take us further—which is why the smell of freshly sharpened pencils might remind you of your elementary school classroom, even if the details of everything else are fuzzy.

We believe those ties between scent, mood, and memory make your home’s fragrance pretty important, too. That’s why our Australian tea tree oil-based air fresheners and odor eliminators are blended with subtle, complementary notes to clear the air—so there’s more room for everything else.

How Exactly Are Fragrances and Feelings Linked, Anyway? 

Here’s the science: scent is one of the brain’s strongest memory triggers. Studies show we retain about 35% of what we smell after three months, compared to just 2% of what we hear. Why the difference? Your olfactory system connects directly to the parts of your brain that control memory and emotion.

That’s why sunscreen might remind you of a beach trip, or freshly cut grass brings to mind summer mornings (or the yardwork you’ve been avoiding—no judgment here). It’s also why luxury hotels, spas, and wellness-focused spaces lean on signature natural scents to make lasting impressions.

The Connections Between Smell and Your Emotional Well-Being

Fragrances don’t just bring up memories; they actually affect your brain’s chemistry. Certain scents activate neurotransmitters like dopamine, endorphins, and serotonin, the feel-good chemicals that spark happiness and relaxation. Because fragrance molecules cross the blood-brain barrier, they act directly on your central nervous system, amplifying their impact. 

Certain scents are linked to specific feelings based on the kind of chemicals that they release. Think lavender for easing stress, orange for a mid-morning boost, or peppermint for focus and clarity. 

That’s the foundation of aromatherapy, a holistic wellness practice that uses natural essential oils to regulate mood, improve focus, and promote balance. 

Naturally Fresh Fragrances Affect Your Mood—Here’s How 

Plant-powered scents aren’t just about smelling good. We know they’re about feeling good, too. 

That’s why every Azuna product blends subtle fragrance with pure, organic Australian tea tree oil to effectively neutralize odors at the source. 

Some of the most well-known pairings include: 

  • Calming scents: Clary sage and chamomile reduce cortisol levels and soothe anxiety. 

  • Energizing scents: Lemon, bergamot, and orange are known to boost energy and mood (and lemon helps with digestion, too).  

  • Comforting scents: Ylang-ylang, peppermint, and sandalwood restore emotional balance and relieve mental fatigue.

Unlike traditional air fresheners that mask odors with chemicals, Azuna clears the air with its natural active ingredient. In fact, all of our products are non-toxic, fresh, and functional. 

Everyday Ways to Use Natural Fragrances 

The right scent can influence your space and your state of mind. A few combinations you can try: 

  • Lavender in the bedroom: for relaxation and deeper sleep. 

  • Citrus in the kitchen: to energize mornings. 

  • Lemon in the bathroom: for a fresh, clean vibe. 

  • Sandalwood or peppermint in your workspace: to sharpen focus and clarity. 

Scents work best when they follow your lifestyle and natural patterns. Seasonal swaps—like warm fall spices and crisp winter evergreens—add another layer of intention. Even these small additions can make your space, and your day, feel a little more intentional.

 

With their proven impact on mood and memory, today’s fragrance can actually help shape how you remember tomorrow.

You may not know this but some of the biggest sources of indoor air pollution are the very products that you use to freshen your home, your clothes and your cars. When used, these products release phthalates and other heavy, unnatural chemicals into your air. That's why, according to the EPA, indoor air (where the average American spends 90% of their time) is 2-5 times more polluted than outdoor air.
