Outline of Final Research Achievements |
This study aimed to explore the relationship between changes in daily stress levels and those in the circadian rhythm (biological rhythm) of salivary cortisol. Participants were 26 employed men who both completed a questionnaire and had their salivary cortisol circadian rhythm measured 3 times at 4-week intervals. Examining the correlation coefficients between the daily stress level and cortisol rhythm revealed that participants for whom the “difference in sleep time between the day before a weekend and a weekday” increased from the initial measurement till that at 4 weeks had a worse cortisol rhythm at 4 weeks. Additionally, participants for whom stress levels increased or energy decreased at 4 weeks had a worse cortisol rhythm at 8 weeks. These results suggest that changes in daily stress at 4 weeks may also impact cortisol rhythm at 8 weeks.

Academic Significance and Societal Importance of the Research Achievements |
本研究は①健常な人を対象とし②同一人物の繰り返し測定により③慢性ストレスが悪化してから身体の健康(コルチゾールの日内リズム)に影響が生じるまでのタイムラグを検討している点において,今までの研究にない学術的意義がある。また本研究の結果,慢性ストレスの変化が,人間が本来持っている生体リズムに影響を与えるまでにはタイムラグがある可能性が示された。これは現場において,ストレスチェック直後だけでなく,しばらく後まで心身の状態をフォローする必要性を示唆するという点で,社会的意義があると考えられる。
