Synchronization of Human Autonomic Nervous System Rhythms with Geomagnetic Activity in Human Subjects

Area of Science:

• Geophysics
• Human Physiology
• Environmental Science

Background:

• The human autonomic nervous system (ANS) regulates involuntary functions.
• Geomagnetic activity, influenced by solar events, can affect Earth's magnetic field.
• Previous research suggests potential links between environmental factors and human health.

Purpose of the Study:

• To investigate the coupling between geomagnetic activity and human nervous system function.
• To analyze heart rate variability (HRV) in relation to dynamic changes in the geomagnetic field.
• To identify correlations between ANS activity and various environmental measures.

Main Methods:

• Continuous monitoring of HRV and the geomagnetic field over 31 days in 10 individuals.
• Time series correlation analysis comparing HRV variables with environmental data (solar wind speed, Kp, Ap, solar radio flux, cosmic rays, Schumann resonance, magnetic field variations).
• Time synchronization, normalization, and removal of circadian rhythms from time series data.

Main Results:

• Significant correlations were found between group HRV and multiple geomagnetic and solar activity measures.
• Participants' HRV rhythms synchronized across different locations with a period of approximately 2.5 days.
• Autonomic nervous system activity demonstrated synchronization with time-varying magnetic fields.

Conclusions:

• Human autonomic nervous system activity is coupled with geomagnetic activity.
• Daily ANS function responds to dynamic changes in solar and magnetic fields.
• A synchronization exists between human HRV rhythms and geomagnetic field-line/Schumann resonances.
