Mechanisms mediated by emotion and microbiome
Since psychological or emotional stress links to cardiovascular health
(78), current available literatures have showed the health benefits of
meditation (79-81), which is like “keeping the pubic region
(Dantian)”. In fact, mindfulness-based meditation may reduce not only
cardiovascular risk factors but also both eCVD (atherosclerosis,
hypertension, and hear failure) (82) and fCVD by lowering psychological
stress, improvement of psychological health and human gut microbiota
(83). More basic studies found that there are some associations (84-86)
among animal behaviors and emotional phenotypes (e.g., anxiety-like
behavior), the gut mycobiota, and host-protective immunity, since the
gut microbiota can regulate central activity by different G proteins and
changes in cellular calcium levels (87). In addition, a new study showed
that high chronic social and psychosocial stressors link to immune aging
and poor health (88) due to changes in naïve and terminally
differentiated T cells and the ratio of
CD4+:CD8+.
