Heart rate and heart rate variability in infants during olfactory stimulation
Annals of Human Biology, 2019 Background: Various plant odours have been shown to decrease heart rate and increase parasympathetic nervous activity. However, ‘innate’ autonomic responses without the influences of experience, assumptions and prejudices of odours remains unclear.
