本研究以台灣南部某專科學校的學生作為樣本，先經過問卷訪問後，施以音樂療法及薰吸迷迭香、佛手柑或依蘭－依蘭精油之芳香療法，並以身心能量分析儀測得樣本參與實驗前後之數據，以t檢定、單因子變異數分析、及Scheffe事後檢定等統計工具進行分析，探討芳香療法與青少年之壓力、疲勞指數、及交感神經與副交感平衡度之間的關係。實驗結果顯示疲勞指數與自覺壓力有顯著的統計正相關；使用迷迭香精油進行芳香療法具有降低疲勞指數的效果；使用迷迭香精油進行芳香療法具有改善交感與副交感神經平衡的效果。本研究建議對於疲勞指數及壓力指數較高之青少年可使用迷迭香精油進行芳香療法來協助其自律神經系統平衡，並降低疲勞指數及壓力指數。
