Leah Lagos: 心率变异性(HRV) 是一种重要的健康指标,它反映了心跳之间变化的幅度,更大的数值代表更好的健康和恢复能力。HRV 与多种临床疾病相关,也可用作提升健康水平的指标。我们可以通过呼吸练习和研究日常生活中影响HRV的因素进行调节,目标是优化心跳间的振荡,使其具有弹性、适应性和灵活性。压力下HRV降低可能与身体为了节省能量而采取的僵化反应有关,但现代社会中这种反应持续时间过长反而有害。应关注应对压力的敏捷性,而非单纯的压力状态。HRV 训练可以优化基线HRV,提高自主神经系统的灵活性,并改善认知功能。通过HRV生物反馈训练,我们可以训练自主神经系统更好地应对压力,提高应对压力的敏捷性。影响HRV范围的因素有很多,包括生物因素、慢性压力、个体敏感性、咖啡因摄入、饮酒、睡眠、运动等。低HRV的体验因人而异,有些人可能会感到思维迟钝、易怒、反应能力下降等。HRV 与大脑功能密切相关,它影响前额叶皮层,有助于提高抑制能力,从而更好地控制行为。高HRV与心血管健康和长寿相关。提高HRV有两种途径:一是通过HRV训练优化基线HRV,二是通过HRV追踪数据来调整生活方式。共振呼吸法是一种特定频率的呼吸练习,可以激活整个神经系统,增强自主神经系统的调节机制。共振呼吸法的呼吸频率通常在每分钟5到6.5次之间,通过使用呼吸配速器可以增强其认知益处。共振呼吸法训练心脏,而非单纯的呼吸,长期坚持可以维持效果。建议在日常生活中利用“power five”呼吸法来调节情绪和认知功能。关于鼻式呼吸对HRV的影响,研究结果并不一致,建议根据个人感受选择合适的呼吸方式。VO2 max 训练和共振呼吸练习可以结合使用,但共振呼吸练习可以帮助调节压力。一些意想不到的干预措施,如针灸和能量疗法,也可能改善HRV。一些补充剂和光照疗法也可能改善HRV。测量HRV时应注意避免运动和其他干扰因素的影响,夜间测量相对可靠。Polar 心率监测器可以可靠地测量HRV,并提供多种测量方式。声音浴等方法可以激活副交感神经系统,但应先了解自身HRV情况,再选择合适的干预措施。共振呼吸法的效果取决于长期坚持,并非短期内就能见效。共振呼吸法训练中常见的错误是过于追求完美,给自己过大的压力。创伤后应激障碍(PTSD)可能会影响HRV训练的即时效果,但坚持练习仍然有效。 Chris: 提出了关于HRV测量、训练方法、以及与其他训练方式结合的问题,并与Leah Lagos进行了深入探讨。

Chapters
HRV was initially used to assess the health of unborn babies and later became a metric for cardiovascular health and other conditions. A subset of researchers and practitioners, including Dr. Lagos, began exploring its potential for improving overall well-being and performance in healthy individuals.
  • HRV was originally used to predict the vitality of unborn babies.
  • It later became a metric for cardiovascular health and other conditions.
  • Dr. Lagos has been researching and practicing HRV for overall well-being and performance enhancement in healthy individuals for the past 17 years.

Shownotes Transcript

Dr Leah Lagos is a clinical psychologist, HRV performance coach and an author.

Heart Rate Variability is one of the most important new metrics that people are using to gauge heart health, longevity and fitness, but improving it can be a minefield. Thankfully Dr Lagos has spent decades optimising the HRVs of some of the world's highest performers and today we get to hear her best advice.

Expect to learn the crucial relationship between HRV and your brain function plus heart health, the best way to improve your HRV, what most people get wrong when trying to optimise their HRV, the most surprising factors that can impact your HRV, the role of breath, stress and fitness and much more...
