Essential Oil Inhalation and Acute Stress Response in Healthy Adults

{ "Essential Oil Inhalation and Stress Response Study", "This study is looking at how inhaling essential oils affects stress in healthy adults. Researchers want to see if essential oils can help reduce your body's and mind's response to stress. You would be assigned to inhale either an essential oil blend or a placebo (an inactive substance that looks and smells the same) through an aroma stick. The study will measure your stress levels using questionnaires and visual scales, as well as physical responses like heart rate, during a temporary stress test and a guided meditation. To join, you need to be between 18 and 45 years old, healthy, and able to attend two in-person visits. The study aims to enroll 200 participants, but its current status is unclear.", "design": "This is a randomized, double-blind, placebo-controlled study with 200 planned participants. This means you would be randomly assigned to receive either the essential oil or a placebo, and neither you nor the researchers would know which one you are receiving.", "commitments": "You would attend two in-person study visits. During these visits, you would inhale from an aroma stick at specific times, undergo a stress test, and participate in a guided meditation session.", "compensation": "Not stated in the trial record.", "follow_up": "Your stress levels will be measured from the start of the study through 30 minutes after the stress test during the first study visit.", }

  • Change in Visual Analog Scale (VAS) Stress Area Under the Curve (AUC)Baseline through 30 minutes post-stressor recovery (Study Visit 1)

    Area under the curve (AUC) for self-reported stress measured using a Visual Analog Scale (VAS) across baseline, stress induction (Trier Social Stress Test - Group version), and post-stressor recovery periods. The VAS-stress scale ranges from low stress to high stress, with higher scores indicating greater perceived stress.
