What is Scent Therapy?

Scent Therapy is a web-based training program developed specifically for medical and care teams working with seniors. Designed to improve cognition by either stimulating or calming the brain, it differs from traditional aromatherapy by focusing strictly on olfaction. Rooted in evidence-based science, this method uses essential oils as aromatic chemicals—not for massage or topical use, but solely for their impact on the brain through the sense of smell.

Lavender is one of the most studied and trusted oils used in this practice.

Why Lavender Is So Widely Used

Lavender (Lavandula angustifolia) has several unique characteristics that make it essential in scent therapy:

• Universal scent recognition
• Low toxicity and high safety profile
• Calming and sedative effects
• Proven benefits for stress, sleep, and agitation

Lavender is gentle enough to use with infants and the elderly, making it ideal across age groups and care environments.

Scientific Studies on Lavender’s Effects

Research supports lavender’s impact on improving sleep and reducing stress:

Better Sleep Quality

• A study by Hirokawa et al. showed lavender improves sleepiness during wakefulness.
• Moeini et al. found participants using lavender had better sleep scores than those in the control group.

Reduced Infant Crying

• Field et al. (2008) observed improved sleep and reduced crying in infants after using lavender scent at sleep.

Systematic Review Findings

A review of 20 randomized controlled trials (PMID: 35708558) found:

• 14 studies showed positive sleep improvements
• Both subjective (questionnaires) and objective (EEG, HRV) methods were used
• Best outcomes were in those without clinical insomnia

Lavender and Dementia Care

Lavender has shown modest but promising effects on behaviour in dementia patients.

“Lavender oil administered in an aroma stream shows modest efficacy in the treatment of agitated behaviour in patients with severe dementia.”
— PubMed Study on Dementia & Lavender

This makes lavender an important tool in non-pharmaceutical care models like Smelling Pink, which integrates scent therapy with dementia support programs.

How to Use Lavender in Your Routine

Here are simple ways to incorporate lavender scent therapy into daily life:

• Olfaction: Add 4–6 drops of lavender essential oil to cotton ball an smell when needed
• Pillow: Add 1- 2 drops to an old dryer sheet and leave in the pillow case 
• Aroma Pads/Diffusion Sticks: Use in memory care for safe, targeted scent delivery.
