geomagnetic fields, space, heart rate variability, autoimmune disease - brief notes
Two mind-blowing articles on the effects of geomagnetic field fluctuations on human health, published in highly ranked peer-reviewed journals. Otsuka et al. (2019) Anti-aging effects of long-term space missions, estimated by heart rate variability https://www.nature.com/articles/s41598-019-45387-6 "Exposure to variable magnetic fields in space resulted in an increase in several HRV endpoints, suggesting that aging may also be slowed down in astronauts in space, as it was for Caenorhabditis elegans 18 . By contrast, our previous 1998–2000 studies (during solar cycle 23) in a subarctic area indicated that magnetic storms, which involved larger magnetic disturbances than those observed during ISS01 and ISS02, suppressed HRV indices in 19 clinically healthy subjects 24 . The decrease in HRV was statistically validated for TF (−18.6%, P = 0.00009), primarily contributed to by VLF (−21.9%, P < 0.000001) in conjunction with ULF (−15.5%, P = 0.00865) and LF (−14.2%, P = 0.001
