Sniff test: saliva may reveal your true feelings
NCT ID NCT07320040
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores whether smelling different fragrances can trigger emotional responses that show up as measurable molecules in saliva. Researchers will collect saliva samples from 240 healthy adults before and after they smell various scents, measuring hormones like cortisol and oxytocin. The goal is to identify a pattern of biomarkers that could indicate positive or negative emotions, potentially leading to a non-invasive way to assess emotional states.
