The Stress-Reducing Effects of Forest Healing Activities in Maladjusted Military Force Members

Abstract

Background and objective: In the Republic of Korea, military service is mandatory. Some of new recruits have the stress from the special environment, which could cause psychological maladjustment. The military forces have operated education programs such as green camp and healing camp. The study was conducted to investigate changes in psychological and physiological stress by conducting forest healing activities along with plant scent treatment for soldiers participating in a green camp. Methods: A total of 52 soldiers were participated including maladjustment soldiers and those recommended by their military units to protect the unfit soldiers who participated in forest healing activities in the green camp. The programs that were certified by the Korea Forest Service between 2014 and 2019, and were applied for stress reduction and relaxation training were classified into stress-coping programs and forest experience programs. Post-hoc surveys and cortisol measurements were carried out. Results: Green camp soldiers experience and differences in the level of stress responses were found to be very statistically significant between the treatment and control groups. The techniques for coping with stress were not significantly different in the control group, and the treatment group showed statistically significant results. In addition, the results of analyzing changes in the concentration of cortisol and measuring physiological stress were very statistically significant in forest healing activities at 4 p.m. Conclusion: Once green camp soldiers face stressful situations, forest healing programs using forest plant scents for green camp soldiers can have positive responses and forest healing activities can reduce psychological and physiological stress responses, improving maladjustment behaviors caused by stress and positively affecting the reduction of cortisol.

Physiological and psychological effects of forest healing focused on plant fragrance therapy for maladjusted soldiers

“…Plant fragrances were used as a mechanism to effectively cope with stress. Directly affecting the olfactory brain with plant fragrances reduces stress with psychological and physiological changes inside the body, thereby facilitating coping mechanisms (Kim. et al, 2020).…”

“…This can help natural therapy using the unique volatile organic compounds of forest fragrances relieve stress and prevent diseases of people today as total care (Song, 2015). Since fragrances of the forest affects the cerebral cortex and hypothalamus and therefore have a therapeutic effect on the whole body, inhaling a pleasant fragrance in a stressed condition will affect the limbic system of the cerebrum that is close to the basic instincts such as anxiety, fear, and rage, thereby relieving stress and changing the person into a stable state so that they can cope positively with stress (Kim et al, 2020).…”

“…Forest healing programs using plant fragrances are part of the five senses that are necessary for classification of forest healing factors (Korea Forest Service, 2011). Plant fragrances can provide a positive effect when maladjusted soldiers are facing stressful situations, and forest healing programs relieved psychological and physiological stress reactions, improved maladaptive behavior of soldiers caused by stress, and reduced cortisol levels (Kim et al, 2020). The positive change of stress relief also served as a direct factor of adjustment to military life (Joe, 2003), and thus forest healing activities using plant fragrances for maladjusted soldiers will help treat and prevent their stress (Kim et al, 2020).…”
