Objective: To explore gender differences in physical and mental relaxation in subjects who watched a forest relaxation video. Methods: The subjects were 12 males and 12 females in their 20’s, with an average age of 21.67±1.00 and 21.42±1.56, respectively. They rested for 5 minutes, and then watched either a forest relaxation video or control video (grey screen, no sound). After the video session, they rested again for 5 minutes. Thus, the total experimental duration was 20 minutes. Before and after the video session, subjects completed visual analog scales (VAS) on mood and Profile of Mood States (POMS) questionnaires. Subjects also pointed out the most comfortable scenes on the video. In addition, we measured their heart rates. Analyses were based on the semantic differential (SD) technique. Results: The heart rate of male subjects decreased just after watching the relaxation video (p<0.05–0.01), and the LnHF increased (p<0.05–0.01), indicating significant activation of the parasympathetic nervous system. Regarding VAS scales, the “refreshment” score increased in male subjects (p<0.01). In females, all three scores for “pleasantness”, “calmness”, and “refreshment” increased after watching the relaxation video (p<0.05–0.001). In addition, the “tension–anxiety” score of the POMS decreased after watching the video (p<0.05). Conclusions: Both male and female subjects felt relaxed after the forest relaxation video. Especially, heart rate changes suggested that male subjects experienced relaxation after the video, whereas female subjects experienced mental relaxation.

本研究は,森林映像の心身反応に関する基礎的検証を行うことを目的に,健康な20歳代24人 (男女各12人,平均年齢21.67±1.31歳) を対象に,森林映像とコントロール映像を用いた.実験は,映像視聴10分,前後に安静5分の合計20分とし,評価指標は,semantic differential technique (SD法),心拍変動,実験前後にVisual Analogue Scale (以下VAS) と気分プロフィール調査 (以下POMS) を用い,自記式質問紙にて森林映像から心地よく感じた内容の回答を得た.森林映像は,穏やかさと好感を得る一方で豊かでダイナミックな印象が得られ,VASから「快適な」「鎮静的な」「リフレッシュした」で得点が上昇し (p <0.001~0.01),POMSから「緊張-不安」の軽減が認められた (p <0.01).心拍変動から副交感神経活動の優位な反応が認められ,今後の活用として心地よく感じる場面の疎密や映像の余韻の活用をすることで快適性やリラックス効果を引き出せる可能性が示唆された.
