The impact of human exposure to environmental factors on Heart Rate Variability (HRV) was examined in the urban space of Tel-Aviv-Jaffa. Four environmental factors were investigated: thermal and social loads; CO concentrations and noise. Levels of HRV are explained mainly by subjective social stresses, noise and CO. The most interesting result is the fact that while subjective social stress and noise increase HRV, low levels of CO are reducing HRV to some extent moderating the impact of subjective social stress and noise. Beyond the poisoning effect of CO and the fact that extremely low levels of HRV associated with high dozes of CO increase risk for life, low levels of CO may have a narcotic effect, as it is measured by HRV. The effects of thermal loads on HRV are negligible probably due to the use of behavioral means in order to neutralize heat and cold effects.
本研究考察了人类暴露于环境因素对心率变异性（HRV）的影响，研究地点在特拉维夫-雅法市的城市空间。研究调查了四种环境因素：热负荷和社会负荷；CO 浓度和噪音。HRV 水平主要受到主观社会压力、噪音和 CO 的影响。最有趣的结果是，尽管主观社会压力和噪音会增加 HRV，但低水平的 CO 会在一定程度上降低 HRV，从而减轻主观社会压力和噪音的影响。除了 CO 的中毒效应以及与高剂量 CO 相关的极低水平 HRV 会增加生命风险这一事实之外，低水平的 CO 可能具有麻醉作用，正如 HRV 所测量的那样。热负荷对 HRV 的影响可以忽略不计，这可能是由于人们使用行为手段来中和热和冷的影响。
