Effects of Breathing Exercises with Favorite Essential Oils on Regulating the Autonomic Nervous System During Nighttime in the Late Luteal Phase

Introduction: During the luteal phase, women often experience various physical and mental symptoms related to irregularities in the autonomic nervous system. Aromatherapy has been reported to alleviate these symptoms and regulate autonomic nervous system function. However, many of them report transient responses in autonomic nervous system activity. We consider that diurnal fluctuations in the autonomic nervous system activity need to be modulated to improve symptoms and enhance quality of life. This study aimed to investigate the effects of aromatherapy on diurnal variations in the autonomic nervous system.
