### Background A considerable number of patients who contracted SARS-CoV-2 are affected by persistent multi-systemic symptoms, referred to as Post-COVID Condition (PCC). Post-exertional malaise (PEM) has been recognized as one of the most frequent manifestations of PCC and is a diagnostic criterion of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Yet, its underlying pathomechanisms remain poorly elucidated. ### Results Upon physical activity, affected patients exhibit a reduced systemic oxygen extraction and oxidative phosphorylation capacity. Accumulating evidence suggests that these are mediated by dysfunctions in mitochondrial capacities and microcirculation that are maintained by latent immune activation, conjointly impairing peripheral bioenergetics. Aggravating deficits in tissue perfusion and oxygen utilization during activities cause exertional intolerance that are frequently accompanied by tachycardia, dyspnea, early cessation of activity and elicit downstream metabolic effects. The accumulation of molecules such as lactate, reactive oxygen species or prostaglandins might trigger local and systemic immune activation. Subsequent intensification of bioenergetic inflexibilities, muscular ionic disturbances and modulation of central nervous system functions can lead to an exacerbation of existing pathologies and symptoms

A long-sought invisible force wrapped around Earth has been detected more than half a century after it was first hypothesized. The field, dubbed the "polar wind," explains how Earth's atmosphere escapes easily and rapidly above the north and south poles, and may have played a role in shaping our planet's thin upper atmosphere.

> If depression is the emotional expression of the immobilization response, then the solution is to move out of that state of defense. Porges believes it is not enough to simply remove the threat. Rather, the nervous system has to detect robust signals of safety to bring the social state back online. The best way to do that? Social connection. For people who don’t prefer social connection, I’ve seen that exercise works well Edit: just want to highlight that polyvagal theory, the main point behind this article, is unsubstantiated thus far https://en.m.wikipedia.org/wiki/Polyvagal_theory
