概括
这项研究发现,即使在缓慢呼吸干预后,自我报告的焦虑症状与生理压力标志物没有相关性. 这表明人们的感受与身体实际应激反应之间存在脱节.
科学领域:
- 心理生理学 心理生理学
- 行为医学是一种行为医学.
- 自主神经系统研究 自主神经系统研究
背景情况:
- 焦虑症状通常被认为反映了生理压力,涉及降低了副交感和增加了交感神经系统活动.
- 然而,直接将自我报告的焦虑与客观的生理压力指标联系起来的经验数据是有限的.
- 这项研究探讨了主观焦虑与客观生理指标之间的关系.
研究的目的:
- 检查自我报告的焦虑指标和压力的生理指标之间的相关性.
- 为了确定心理压力测量是否与自主神经系统功能保持一致.
- 评估缓慢呼吸干预对这种关系的影响.
主要方法:
- 来自88名参与者,12周缓慢呼吸临床试验的数据的二次分析.
- 使用PROMIS焦虑CAT (计算机化适应性测试) 评估的心理压力.
- 通过心率变化 (HRV) 谱分析 (RMSSD,LF/HF比率) 和血压变化 (LFsys) 评估的生理压力.
主要成果:
- 干预后观察到自我报告的焦虑明显减少 (-4.85 ± 5.53).
- 然而,在所有时间点 (基线,6,12周) 和随着时间的推移,在PROMIS焦虑得分和生理压力指标之间发现了较低的相关性.
- 自主音调测量 (LF/HF比率,LFsys) 与自我报告的焦虑有很差的相关性.
结论:
- 自我报告的焦虑和客观的生理测量压力之间存在着显著的脱节.
- 缓慢呼吸等行为干预措施可以减少主观焦虑,但不一定改变潜在的生理压力标志物.
- 需要进一步的研究来了解心理痛苦和自主神经系统调节之间的复杂相互作用.

Psychoneuroimmunology: Cardiovascular Disease
402
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.

Physiological Foundation of Stress
576
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Psychological Responses to Stress
483
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Stress and Mental Health
804
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Introduction to Stress and Lifestyle
513
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...
