Influence of Magnetic Fields, Including the Planetary Magnetic Field, on Complex Life Forms: How Do Biological Systems Function in This Field and in Electromagnetic Fields?

Abstract

Overview

Life on Earth has developed under specific biochemical and biophysical boundary conditions, such as nutrients, water, gravity, radiation, and the planetary geomagnetic field (GMF). Complex organisms, including humans, possess neurological, neuromuscular, and cardiovascular systems which not only function using electromagnetic fields but also incorporate materials like iron ions with magnetic properties.

Findings

• Complex life forms, such as humans, may be significantly influenced by magnetic fields, including those generated internally and externally.
• Proteins and physiological processes often involve iron ions, which can respond to ambient magnetic fields.
• It remains unclear the extent to which humans utilize exogenous magnetic fields to regulate bodily function or what changes occur when the geomagnetic field is absent.
• Space flight — especially missions to destinations like Mars — offers a unique environment to study human adaptation in the absence of Earth's natural magnetic field.
• There is a lack of understanding regarding how the continued presence or absence of the GMF affects human biology and health.

Conclusion

The involvement of magnetic fields in numerous human physiological processes is evident, but many specifics remain unexplored. The lack of research into this critical area presents a challenge for both health professionals and space explorers, as changes or removal of the GMF may pose health risks that are currently not well understood. The intersection between magnetic fields and human health is a vital and under-investigated field, highlighting the need for further studies, especially as humanity ventures beyond Earth.
