Like meditation, self-regulation skills train attention and teach people how to redirect and sustain attention in particular ways that can be used prior to and during challenging events as well as practiced over time to build deeper nervous system balance via neuroplasticity.
Autonomic nervous system balance can be assessed non-invasively via the use of heart rate variability (HRV).
18 The mechanisms underlying this finding remain unclear, but alterations in cardiac autonomic nervous system balance may be involved.
The ratio of LF to HF in HR variability was also calculated as an index of the autonomic nervous system balance [ 17].
Studies showed that particulate air pollution exposure is associated with rapid changes in autonomic nervous system balance, favoring sympathetic nervous system activation and parasympathetic withdrawal leading to changes in the pattern of breathing, heart rate, and heart rate variability.
There are three general pathways that could link PM2.5 exposure with changes in CV physiology: systemic inflammation (pathway 1), altered autonomic nervous system balance (pathway 2), and direct effects of particles or constituents reaching the circulation (pathway 3) (Brook 2008).
This study shows that an acute exposure of healthy young adults to concentrated coarse CAPs resulted in significant changes in indices of pulmonary inflammation, hemostasis, and autonomic nervous system balance.
The recent AHA statement suggests that inhalation of particulate matter may result in disturbance of the autonomic nervous system balance or heart rhythm by particle interactions with lung receptors or nerves (Brook et al. 2010).
The particle pollution in CAD patients during physical activity may increase systemic arterial vascular narrowing, as manifested by increased peripheral blood pressure and HR [ 44, 45], and promote arterial vasoconstriction via altering cardiovascular autonomic nervous system balance [ 46– 46].
There might be riots on the streets and strikes, but the electorate may take a grown-up view of fiscal consolidation, particularly if it is concentrated on spending cuts rather than tax increases.Yet that in turn raises another question: why are politicians still so nervous about balancing the books?
