Mechanisms…
When you inhale a scent, the odor molecules travel directly to the limbic system of the brain, which includes the amygdala (emotion center) and hippocampus (memory center), bypassing the usual sensory processing pathways. This direct link explains why smells can trigger immediate and intense emotional responses and vivid autobiographical memories (the “Proust effect”). Olfactory receptors also exist in skin cells and can respond to scents.
Did You Know?
Scents can influence heart rate, digestion, and even cellular growth, with research showing tumor cells reacting to certain odours.
Stats/ Studies
- In a study of patients undergoing MRIs, 64% of those who inhaled a vanilla scent, experienced a drop in anxiety levels.
- Lab studies on skin cells found that a synthetic sandalwood scent, increased cell proliferation by 32% and cell migration by nearly 50%.
- A study of elderly individuals found that those with a weak sense of smell had a 46% higher risk of mortality over the next decade, showing its importance as a general health marker.
Application
- Aromatherapy.
- Smell Retraining Therapy (SRT): For those with lost smell (post-COVID, etc.), sniffing varied scents (lemon, coffee, spices) daily helps regenerate neural pathways and restore scent perception.
- Hospitals & Clinics: Can lower patient stress, and calm staff.
Therapies
Trauma/PTSD:
Scents linked to positive experiences (like lavender) can be used to build “safety memories” to counter anxiety.
Emotional & Neurological Healing:
Stress reduction, mood improvement and PTSD management.
Physical & Cellular Healing:
Wound Healing - Studies have shown that a synthetic sandalwood scent (Sandalore) binds to an olfactory receptor in skin cells (OR2AT4), triggering a calcium signaling cascade that dramatically increases cell proliferation and migration, key processes in repairing damaged skin.
Immune Response:
Olfactory receptors in immune cells, like macrophages, can detect molecules and influence the body’s inflammatory response. Understanding this mechanism may lead to novel therapies for inflammation-driven diseases like atherosclerosis.
