Brief Summary

Sleep disorders affect human health tremendously. It has been reported that aromatherapy by fragrance inhalation can be used as an adjuvant therapy to modulate parasympathetic nervous activity for relieving stress and mood, and promoting sleep quality. Many researches confirmed that lavender essential oil can be used as an adjuvant therapy for sleep disorders. It can effectively relieve stress and modulate physical and mental status. However, many studies about aromatherapy lack sleep detection instruments to objectively confirm their effects on sleep physiology. Therefore, this study adopts Easy sleep complex essential oil as the experimental group. The lavender essential oil containing orange, petitgrain, rose, lavender, rosewood, ho wood, amyris essential oil and lavender oil is chosen as control group. The subjects will be randomly assigned to one of the two groups. The efficacy results will be evaluated and compared between the two groups. The investigators expect that aromatherapy by fragrance inhalation with Easy sleep complex essential oil will improve sleep quality more effectively than lavender essential oil.
