🌬️ How Scent Affects Mood: The Science Behind the Feeling
Unlike sight or sound, smell has a direct pathway to the brain’s emotional centre. When you breathe in a fragrance, the olfactory system sends signals straight to the limbic system — the part of the brain responsible for emotion, memory, and mood. That’s why a single scent can instantly transport you to a moment, a place, or a feeling.
Recent studies highlight just how powerful fragrance can be:
Scent triggers measurable emotional responses
Research shows that fragrance can positively influence emotions, comfort, and daily experiences, with noticeable effects on happiness and behaviour.
Aromatic compounds interact with mood‑related neurotransmitters
Certain fragrance molecules influence brain activity linked to mood, memory, and wellbeing. Lavender, rosemary, and herbal scents are known for their calming, uplifting effects.
Specific fragrances reduce stress and promote relaxation
Studies exploring the “Relaxation Scale of Flavours and Fragrances” found that citrus and mint — especially lemon‑lime — reliably support relaxation and emotional balance.
Long‑term home fragrance use supports wellbeing
Candles, diffusers, and room sprays can ease anxiety, relax the mind, and improve overall wellbeing through consistent olfactory stimulation.
Scent influences mood consciously and unconsciously
Fragrance affects emotion and cognition even before we’re aware of it, shaping how we feel throughout the day.
Together, these findings show that fragrance isn’t just a luxury — it’s a truly meaningful tool for emotional support and daily wellbeing.

What is Blue Monday?
Blue Monday is often referred to as “the most depressing day of the year,” typically falling on the third Monday of January. While the science behind it is debated, many people do feel a dip in mood during mid‑winter due to darker days, colder weather, and post‑holiday fatigue.
Can fragrance really improve your mood?
Yes. Research shows that scent has a direct connection to the brain’s emotional centre, meaning certain fragrances can influence mood, reduce stress, and support overall wellbeing. Aromas like citrus, lavender, mint, and herbal blends are especially known for their uplifting or calming effects.
How does scent affect the brain?
When you inhale a fragrance, your olfactory system sends signals straight to the limbic system — the part of the brain responsible for emotion, memory, and mood. This is why scent can instantly trigger feelings, memories, and emotional responses.
Which scents are best for boosting mood on Blue Monday?
Uplifting scents like citrus, mint, and fresh herbal blends can help energise and brighten your mood. Calming scents such as lavender, amber, and soft florals can ease stress and promote relaxation.
Do home fragrances like candles and diffusers help with wellbeing?
Studies show that long‑term use of home fragrance — including candles, diffusers, and room sprays — can support relaxation, reduce anxiety, and create a more comforting environment through consistent olfactory stimulation.
How do I choose the right scent for my mood?
Look for products with a scent triangle that highlights top, middle, and base notes. This helps you understand the full fragrance profile and choose a scent that matches how you want to feel — whether that’s uplifted, calm, cosy, or refreshed.
