Abstract
|
|
|
Purpose: This study aims to compare the effects of inhalation of blended aroma essential oils on autonomic nervous system (ANS) according to blood type (BT).
Methods: Peppermint, rosemary, eucalyptus, pine, and lemon essentials oils were mixed in the ratio of 12:4:2:1:1, respectively. In total, 32 middle-aged women inhaled the blended aroma oil for 28 min. Heart rate variability (HRV) was measured and an electroencephalogram (EEG) was conducted before; immediately after; and 4, 8, 12, 16, 20, and 24 min after essential oil inhalation.
Results: Analysis revealed significant differences in BT-time interaction for average heart rate (HR), low frequency/high frequency activity ratio (LF/HF), and relative alpha.
Conclusion: The effects of aroma essential oil inhalation on ANS are dependent on the duration of inhalation and individual BT.
