| Outline of Final Research Achievements |
We investigated the physiological responses of infants to inhalation of odorous components of coniferous trees. The participants were 52 infants aged 1–3 months. Each infant was exposed to the odors of α-pinene, limonene, α-ketone and air (as a control) for 2 min. There was a rest period of 2 min prior to and after the exposure. During this rest-inhalation-rest session, cerebral and cardiac activities were continuously monitored. The heart rate and heart rate variability were calculated from the electrocardiogram. The measurements were repeated at 2-week intervals until the infants were 3.5 months old. Data were excluded from analysis in cases where the infants fell asleep or cried. Heart rate significantly decreased in response to exposure to α-pinene (p
