Background: In recent years, the physiological relaxation effects of natural environments have been widely exploited, and although individual differences in the effects of forest therapy are known, assessment methods have not been clearly established. This study used a classification based on Type A and Type B behavior patterns to explain individual differences in physiological responses to forest environments. Methods: We performed physiological experiments in 44 forest and urban (controls) areas. In total, 485 male university students (age, 21.8 ± 1.6 years) participated in the study. The subjects were asked to visit forest or urban environments randomly and observe each landscape for 15 min. The subjects’ pulse rates and blood pressures were tested to evaluate their physiological responses. The Kwansei Gakuin daily life questionnaire was used to identify Type A and Type B behavior patterns in subjects. Results: The pulse rate was significantly lower in the Type B group after exposure to forest areas than after exposure to urban areas, whereas no significant difference was observed in the Type A group. In addition, the pulse rate was significantly lower in the low scoring subjects in the Type B group, which was consistent with changes in their diastolic blood pressure. Conclusions: These results suggest that individual differences in pulse rate and blood pressure in response to forest environments can be explained by Type A and Type B behavior patterns.

基于 A 型和 B 型行为模式的森林声音心理效应的个体差异

背景：近年来，自然环境的生理放松效应被广泛利用，虽然已知森林疗法效果的个体差异，但尚未明确建立评估方法。本研究使用基于 A 型和 B 型行为模式的分类来解释对森林环境的生理反应的个体差异。方法：我们在 44 个森林和城市（对照）区域进行了生理实验。总共有 485 名男性大学生（年龄 21.8 ± 1.6 岁）参与了这项研究。受试者被要求随机访问森林或城市环境，并观察每个景观 15 分钟。测试受试者的脉搏率和血压以评估他们的生理反应。Kwansei Gakuin 日常生活问卷用于识别受试者的 A 型和 B 型行为模式。结果：暴露于森林地区后，B 型组的脉搏率明显低于暴露于城市地区后，而在 A 型组中没有观察到显着差异。此外，B 型组低评分受试者的脉搏率显着降低，这与其舒张压的变化一致。结论：这些结果表明，响应森林环境的脉率和血压的个体差异可以用 A 型和 B 型行为模式来解释。暴露于森林地区后，B 型组的脉搏率显着低于暴露于城市地区后，而 A 型组没有观察到显着差异。此外，B 型组低评分受试者的脉搏率显着降低，这与其舒张压的变化一致。结论：这些结果表明，响应森林环境的脉率和血压的个体差异可以用 A 型和 B 型行为模式来解释。暴露于森林地区后，B 型组的脉搏率显着低于暴露于城市地区后，而 A 型组没有观察到显着差异。此外，B 型组低评分受试者的脉搏率显着降低，这与其舒张压的变化一致。结论：这些结果表明，响应森林环境的脉率和血压的个体差异可以用 A 型和 B 型行为模式来解释。
