Down to earth - A new type of hygiene.

ABSTRACT

In the current issue of the Biomedical Journal a special section introduces the influence earthing (or lack thereof) has on the human body. A variety of enlightening articles elaborate how electromagnetic hygiene involving earthing may lower the occurrence of various diseases, reduce inflammation, improve sleep and help maintain a well-functioning circadian rhythm. Another article has a closer look at the connection between sunspot extrema and pandemics, and the relief grounding may exert on the main complications encountered in COVID-19 infection. This issue furthermore contains articles about the principles and safety of COVID-19 mRNA vaccines, the use of lidocaine against the cytokine storm triggered by SARS-CoV-2, and hypocalcemia as predictive marker in COVID-19. The reader learns about two miRNAs playing a role in colorectal cancer, diffusion characteristics of cerebrospinal fluid, and an approach of rotational radiography leading to a lower radiation exposure. The final articles present the use of dynamic arthroscopy to refine diagnosis of the origin of shoulder pain, the application of traditional Chinese medicine in analysis of chronic kidney disease, and an exchange concerning neuroimaging abnormalities in pediatric COVID-19 cases.
