Hosted by the International Federation of Aromatherapists (IFA), Aromatherapy Awareness Week is a global initiative dedicated to highlighting the clinical value of aromatherapy and the positive role it can play in supporting health and wellbeing. It celebrates the vital contribution aromatherapists make across the UK and internationally to individuals, families, and communities around the world.
The week also invites people to take a closer look at their own wellbeing, explore complementary approaches to self-care, and recognise how aromatherapy can support both physical and emotional health.
10 Facts About Aromatherapy
~Smell is the only sense directly linked to the brain’s emotional centre
Olfactory signals travel straight to the limbic system, which controls emotion, behaviour, and memory - without being filtered first.
~Aromas can influence memory and recall
Because the hippocampus (memory centre) is part of the limbic system, scent stimulation may influence memory processing and recall.
~Essential oils can trigger immediate physiological responses
Studies show changes in heart rate, blood pressure, muscle tone, and brain activity can occur within minutes of inhalation.
~Over half of aromatherapy research uses inhalation
Around 58% of studies investigate inhalation as the primary method, highlighting its importance in affecting the nervous system.
~Essential oil molecules can influence the brain in multiple ways
They can act via the olfactory system, enter circulation through the lungs, and in some cases cross the blood–brain barrier to interact with brain regions.
~Aromatherapy may influence neurotransmitters
Certain essential oil compounds are thought to affect neurotransmitters linked to mood, attention, and memory, although research is still developing.
~Lavender dominates research in this field
Around 30% of studies focus on lavender, making it the most researched essential oil in relation to the nervous system.
~Citrus oils are the second most studied group
Oils like lemon and bergamot account for roughly 24% of research, often linked to mood and alertness.
~Some essential oils show cognitive effects in studies
For example, rosemary has been associated with improved memory performance in controlled trials.
~Brain imaging shows measurable changes after exposure
Techniques such as EEG and near-infrared spectroscopy have demonstrated changes in brain activity and oxygenation following exposure to certain aromas.
