THE IMPACT OF NATURE IMMERSION THERAPY ON BLOOD PRESSURE IN HYPERTENSIVE SUBJECTS: A PILOT STUDY

Background and Objective:Conscious nature immersion therapy, termed "Vitamin N", has shown promise in reducing blood pressure levels in individuals with or without hypertension. This pilot study aims to assess the effect of nature immersion on blood pressure specifically in hypertensive subjects. Methods:A convenience sample of stable hypertensive individuals participated in a standardized 3-hour nature immersion session. Systolic and diastolic blood pressure levels were recorded before the intervention (Phase I), after 30 minutes of the intervention (Phase II), and 48 hours post-intervention (Phase III). Statistical analysis employed a one-way non-parametric ANOVA, Kruskal-Wallis test, and Dunn's post hoc test, with a bilateral significance level of 95%. A criterion of at least 3 mmHg reduction in blood pressure was set for clinical significance. ResultsEighteen participants, comprising 12 women (64.67%) and 6 men (33.33%), with a mean age of 60 +/- 9.04 years and 61 +/- 6.88 years, respectively, were included. Six individuals had a medical history of Diabetes Mellitus Type 2, and one had a history of coronary heart disease. Significant differences in median systolic (MSP) and diastolic pressures (MDP) were observed across the three phases (p<0.05). Notably, Phase II and Phase III showed consistent reductions in blood pressure compared to Phase I, exceeding the established 3 mmHg reduction criterion. Conclusions:Conscious nature immersion therapy ("Vitamin N") exhibited a significant effect in lowering both systolic and diastolic blood pressure levels among hypertensive individuals. These findings suggest the potential of nature immersion as a non-pharmacological intervention for managing hypertension.
