The effect of lavender on anxiety and sleep quality in patients treated with chemotherapyBACKGROUND:
A cancer diagnosis is a serious stressor that is associated with anxiety, depression, sleep disorders, and inability to fulfill daily routines. Many pharmacologic and nonpharmacologic options are available to help patients with cancer manage anxiety.OBJECTIVES:
This randomized, controlled trial examined the effects of lavender oil aromatherapy on anxiety and sleep quality in patients undergoing chemotherapy.METHODS:
70 patients were randomly assigned to a lavender oil group, a tea tree oil group, and a control group with no oil. A patient identification form, the State-Trait Anxiety Inventory, and the Pittsburgh Quality Sleep Index (PSQI) were used to measure anxiety and sleep quality before and after chemotherapy.FINDINGS:
State anxiety before and after chemotherapy did not vary among groups. The authors compared trait anxiety values before and after chemotherapy and found a significant difference in the lavender group. In addition, a significant change in PSQI measurements before and after chemotherapy was observed.
