The Effect of Lavender Inhalation on Anxiety, Sleep, and Blood Pressure

This study aims to determine the effects of lavender oil inhalation on anxiety, sleep quality, and blood pressure in patients with primary hypertension. The study is designed as a double-blind randomized controlled trial. The study population consists of patients presenting to the Cardiology Outpatient Clinic of Ardahan State Hospital. Participants are randomly assigned to an experimental group, which will receive a total of 12 lavender oil inhalations three times a week for one month, or to a control group, which will continue routine treatment and care. Data will be collected using the Hypertension Diagnostic Form, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index. Statistical analyses will be conducted to compare outcomes between the experimental and control groups.

It is designed as a double-blind randomized controlled trial. Patients presenting to the Cardiology Outpatient Clinic of Ardahan State Hospital will be recruited for the study. Participants will be randomly assigned to an experimental group, which will receive 12 lavender oil inhalations three times a week for one month, or to a control group, which will continue routine care. Data will be collected using the Hypertension Diagnostic Form, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index. The study will assess whether lavender oil inhalation affects anxiety, sleep quality, and blood pressure in this population. Statistical analyses will be conducted to compare outcomes between the experimental and control groups.

Other

Participants receive lavender oil inhalation three times per week for one month (total of 12 sessions) using a standardized diffuser. This intervention is provided in addition to routine care for primary hypertension. Outcomes measured include anxiety, sleep quality, and blood pressure before and after the intervention.

Primary outcomes

  1. Anxiety

    Time frame: Baseline, Week 2, Week 4

    Measured using the Beck Anxiety Inventory (BAI) at baseline, week 2, and week 4. Higher scores indicate higher anxiety.

  2. Blood Pressure

    Time frame: Baseline, Week 2, Week 4

    Measured using the Hypertension Diagnostic Form at baseline, week 2, and week 4. Includes systolic and diastolic measurements.

Secondary outcomes

  1. Sleep quality

    Time frame: Baseline, Week 2, Week 4

    Measured using the Pittsburgh Sleep Quality Index (PSQI) at baseline, week 2, and week 4. Higher scores indicate poorer sleep quality
