Summary

Schumann resonance (SR) exposure was associated with lower blood pressure (BP) and double product (DP). Individuals with fewer disease-related illnesses (DRI) and healthier lifestyles (HLS) exhibited greater BP reactivity to SR.

Area of Science:

  • Environmental Health
  • Cardiovascular Physiology
  • Geophysics

Background:

  • The Earth's electromagnetic field, including Schumann resonance (SR), is a ubiquitous environmental factor.
  • Previous research has explored potential biological effects of electromagnetic fields, but their impact on human physiological parameters like blood pressure (BP) and heart rate (HR) remains under investigation.
  • Understanding these interactions is crucial for assessing environmental influences on human health.

Purpose of the Study:

  • To determine if Schumann resonance (SR) influences blood pressure (BP), heart rate (HR), and depression levels in adults.
  • To investigate the association between blood pressure reactivity to SR (BPR-SR) and health-related lifestyle (HLS), disease-related illnesses (DRI), and depression.

Main Methods:

  • Fifty-six adults in Japan participated in a seven-day ambulatory BP monitoring study.
  • Participants completed questionnaires on health-related lifestyle (HLS), disease-related illnesses (DRI), and depression (Geriatric Depression Scale-Short Form).
  • Systolic and diastolic BP, mean arterial pressure (MAP), double product (DP), and HR were compared between normal and enhanced SR days using t-tests; correlations with BPR-SR were analyzed using Pearson's correlation.

    • Main Results:

    • Group mean systolic BP (SBP), diastolic BP (DBP), MAP, and DP were significantly lower on enhanced SR days compared to normal SR days (P=0.005–0.036).
    • Disease-related illnesses (DRI) showed a negative association with BPR-SR across SBP, DBP, MAP, and DP (P=0.003–0.024), indicating better health status with lower BP on enhanced SR days.
    • Health-related lifestyle (HLS) was negatively associated with BPR-SR in DBP and MAP (P=0.016–0.029), and males exhibited higher BPR-SR in DBP and MAP than females (P=0.004–0.016).

    Conclusions:

    • Enhanced Schumann resonance (SR) days were associated with lower blood pressure (BP) and double product (DP).
    • Individuals with fewer disease-related illnesses (DRI) and healthier lifestyles (HLS) demonstrated greater BP reactivity to SR.
    • Further research with larger sample sizes is warranted to generalize these findings on SR's potential health effects.
