Investigating the Stress-Reducing Effects of Lavender Oil in Academic Settings
February 24, 2025
Studies have found that inhaling lavender essential oil reduced stress, heart rate, and blood pressure in students during exams. The study supports lavender aromatherapy as a simple, effective way to manage academic stress.

This study investigates the impact that Lavandula officinalis essential oil (LvEO) has on stress-induced variations. Researchers used behavioral tests and molecular analysis to determine whether inhaling LvEO can alleviate stress as opposed to water vapor. The group was focused on four groups: (-)/H2O, stress (-)/LvEO, stress (+)/H2O, and stress (+)/LvEO group. The researchers hypothesized that the lavender oil would reduce stress levels compared to the placebo group. Since academics affect stress, researchers sought to determine whether exposure to LvEO could be an alternative process to manage stress and improve academic experience.
Figure 1 describes the study strategy of a clinical trial among pharmacy students and the impact of lavender oil on academic stress. This randomized, single - blind placebo - (controlled) trial utilized lavender oil (independent variable) to monitor stress scores, blood pressure, and heart rate (dependent variables). Experimental groups were given lavender oil or a placebo, whereas the control group received no treatment at all. In the lavender oil group, results revealed a notable drop is stress ratings (F=244.865, p=0.0001), systolic blood pressure (F=11.141, p=0.0001), and heart rate (F=8.537, p=0.0001) relative to the control during examinations. The figure confirms that anxiolytic effects of lavender oil does reduce stress related behavior
Figure 2 assesses the mean change in test scores at three points in time (control variable). They assessed whether intervention had an impact on the treatment of the placebo and experimental groups (independent variables) while monitoring changes in stress before the exam, during the exam, and after the exam (dependent variables). At the pre-exam stage, all perceived academic stress scores were approximately 2.5. During the exam period, the stress levels peaked to a 4.2 for the control group, while the placebo and experimental had slight declines to about 2.5 during the post-exam. These findings indicate that LvEO helps regulate stress levels, supporting the hypothesis that lavender inhalation alleviates stress levels that come with academic stress.
Figure 3 shows how the stools of pharmacy students changed during an exam time. The data was gathered from a randomized placebo-controlled trial which underwent treatment for aromatherapy (lavender oil, a sugar pill, or no treatment) (independent variables). The change in stools was shown by the Bristol Stool Chart (dependent variable). No major differences were observed in stool patterns among the control, placebo, and lavender oil groups (F=2.143, p > 0.05). This shows that aromatherapy with lavender oil doesn’t change stools much during times of academic stress. The figure supports the findings that physiological functions do affect digestions and stool patterns, while the experimental and placebo groups remained consistent.
Figures 1, 2, and 3 all support the hypothesis that lavender oil can have therapeutic effects, regulating stress and anxiety levels. Figure 1 shows clear benefits for using lavender oil in the experiment evidenced in Figure 2 which shows a significant drop in perceived stress scores during exams (F=20.866, p<0.0001). Figure 3 shows improvements in physiological reactions, lower heart rate, and blood pressure. Future research should explore long-term impacts and potential applications in academic settings to broaden these findings’ relevance. For best results in lowering school-related stress, it could look into the dose-response link of lavender oil.
