This study analyzed nocturia (nighttime urination) data, revealing weekly and near-weekly patterns. These variations may link to social schedules and natural geomagnetic changes.

Area of Science:

  • Chronobiology
  • Environmental Health

Background:

  • Nocturia, or nighttime urination, is a common symptom impacting quality of life.
  • Understanding the temporal patterns and potential environmental influences on nocturia is crucial for developing effective management strategies.

Purpose of the Study:

  • To analyze temporal variations in nocturia using chronomics.
  • To investigate potential influences of geomagnetic activity on nocturia patterns.

Main Methods:

  • Reanalysis of a 4-year personal urinary record from a 54-year-old male with benign prostatic hyperplasia.
  • Application of least squares spectral analysis to urinary data and concurrent environmental variables.
  • Identification of periodicities within the recorded data.

Main Results:

  • Confirmed previously reported monthly variations in nocturia.
  • Identified two distinct periodicities: a precise 7-day period and a near-weekly period.
  • The 7-day period suggests resonance with exogenous factors like weekly social schedules.
  • The near-weekly period indicates a possible partial resonance with natural geomagnetic fluctuations.

Conclusions:

  • Nocturia exhibits complex temporal structures beyond simple monthly cycles.
  • Both social and natural environmental factors, including geomagnetic changes, may influence nocturia frequency.
  • Further research is warranted to elucidate the precise mechanisms linking environmental factors to nocturia.
