Moreover, research has suggested that spontaneous laughter contributes to physiological and psychological health. For example, Berk et al.（1989） reported on the relationship between natural killer cell activity and laughter. They also reported that mirthful laughter appears to reduce serum levels of cortisol, dopamine, endorphins, and growth hormone. These biochemical changes have implications for the reversal of the neuroendocrine and classical stress hormone response. The current study investigated the effects of spontaneous laughter on cardiovascular and autonomic nervous response to a humorous video preceding a task involving passive coping with stress.\nThirty university students were randomly divided into a group that watched a video of individuals laughing and that laughed spontaneously（n=15）and a control group that watched a monitor with a white screen（n=15） during a passive coping situation. Heart rate（HR）, systolic blood pressure （SBP）, diastolic blood pressure（DBP）, low-frequency（LF）and high-frequency（HF）heart rate variability, the LF/HF ratio, and baroreflex sensitivity （BRS）were measured throughout the experiment.\nResults revealed that coactivation of the sympathetic and parasympathetic nervous system occurred during display of the image of laughter, and the stress response was suppressed during the task involving passive coping with stress. Repeatedly experiencing positive emotions, i.e. laughter and humor, may cause suppression of the sympathetic nervous system or activation of the parasympathetic nervous system, possibility reducing a depressive state.\n\n【目的】近年、遊戯的笑いのようなポジティブな情動が、ストレス状況において神経内分泌系反応を改善すると示唆されている。さらに、自発的笑いは、身体的・心理的健康に寄与すると示唆されている。たとえば Berk et al.（1989）は、NK細胞と笑いとの関連性について、遊戯的な笑いが、血清中のコルチゾール、ドーパミン、エンドロフィン、成長ホルモンを低下させると報告している。これらの生化学的変化は、神経内分泌反応とストレスホルモン応答が一致していることを示している。本研究では、受動的対処ストレス課題に先行する笑いビデオによる自発的笑いの心臓血管系反応および自律神経系反応への効果を検討する。\n【方法】30名の大学生笑い映像を呈示する映像条件（n=15）とホワイト画面を呈示する統制条件（n=15）にランダムに割り当てた。実験セッション中、心拍（HR）、収縮期血圧（SBP）、拡張期血圧（DBP）、心拍変動における低周波成分（LF）、高周波成分（HF）、LF/HF比、圧受容体反射（BRS）を測定した。\n【結果と考察】笑い映像提示期おいて、交感神経系と交感神経系の共亢進が生じ、受動的対処ストレス課題期では、そのストレス反応が抑制された。笑いやユーモアのポジティブ感情を繰り返し経験することにより、交感神経系の抑制あるいは副交感神経系の活性化を生じさせ、抑うつ状態を低下させる可能性を示唆している。","subitem_description_type":"Abstract"}]},"item_5_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_5_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03882152"}]},"item_5_text_39":{"attribute_name":"本文言語","attribute_value_mlt":[{"subitem_text_value":"日本語"}]},"item_5_text_42":{"attribute_name":"ID","attribute_value_mlt":[{"subitem_text_value":"BKK0003551"}]},"item_5_text_7":{"attribute_name":"Author","attribute_value_mlt":[{"subitem_text_value":"Ishihara, Shunichi"}]},"item_5_text_8":{"attribute_name":"所属機関","attribute_value_mlt":[{"subitem_text_value":"文教大学人間科学部"}]},"item_5_text_9":{"attribute_name":"Institution","attribute_value_mlt":[{"subitem_text_value":"Bunkyo University, Faculty of Human Science"}]},"item_5_version_type_35":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石原, 俊一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-25"}],"displaytype":"detail","filename":"BKK0003551.pdf","filesize":[{"value":"810.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BKK0003551.pdf","url":"https://bunkyo.repo.nii.ac.jp/record/7378/files/BKK0003551.pdf"},"version_id":"4553a30c-d406-4a9f-9dba-181b6dd70503"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"受動的対処事態"},{"subitem_subject":"自発(笑)"},{"subitem_subject":"心拍"},{"subitem_subject":"血圧"},{"subitem_subject":"心拍変動"},{"subitem_subject":"passive coping situation"},{"subitem_subject":"spontaneous laughter"},{"subitem_subject":"heart rate"},{"subitem_subject":"blood pressure"},{"subitem_subject":"heart rate variability"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"受動的対処事態における自発的笑いの生理心理学的効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"受動的対処事態における自発的笑いの生理心理学的効果"},{"subitem_title":"The psychophysiological effects of spontaneous laughter in a passive coping situation"}]},"item_type_id":"5","owner":"3","path":["816"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-25"},"publish_date":"2019-03-25","publish_status":"0","recid":"7378","relation_version_is_last":true,"title":["受動的対処事態における自発的笑いの生理心理学的効果"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T15:12:53.954967+00:00"}
