“…Previous reports have not found gender differences [7,9], but there is some evidence for such differences in the effects of various types of magnetic field [26][27][28][29][30][31]. Our results do not agree with some studies in which suicide numbers were found to be inversely related to geomagnetic activity [12,13].…”

Objectives Previous studies have shown a positive relationship between geomagnetic disturbances and an increased incidence of suicide. The Japanese suicide rate is the ninth highest in the world, but there have been no reports examining the relationship between geomagnetic disturbance and the number of suicides, and, therefore, this paper examines this relationship. Methods The number of Japanese suicides per month from January 1999 to December 2010 was obtained, and it was found that a total of 262,596 males and 102,539 females committed suicide during this period. To adjust the other factors which affect the number of suicides, a multiple linear regression analysis with backward elimination was carried out, with the monthly number of suicides as the response variable and the monthly mean K index value, monthly mean number of sunspots, monthly mean unemployment rate, proportion of elderly people (%), monthly mean air pressure (hPa), monthly mean air temperature (°C), monthly mean humidity (%), and monthly mean day length (h) as the explanatory variables. ResultsIn the multiple linear regression analysis for males, the monthly mean K index value was associated with the monthly number of suicides, but in females, the monthly mean K index value was not associated with the monthly number of suicides. Conclusion In this study, we generated a hypothesis that geomagnetic disturbances may trigger male suicides.

“…In male rats, the relationship was a positive correlation, but in female rats the relationship was a negative correlation. This finding corresponds with evidence for sex differences in the effects of various types of magnetic field [12][13][14][15][16][17].…”

Abstract-There is some evidence that exposure of various animals to a power-frequency magnetic field can cause increases in body mass. However, the precise nature of the relationship is not clear, particularly for long-term exposure. To clarify the relationship between long-term power-frequency magnetic field exposure (2 years) and animal body mass, we conducted a pooled analysis of data in two studies to examine the impact of power-frequency magnetic field exposure on body mass as compared with sham-exposed rats of both sexes. Relative body mass was the response variable, and the study duration (in weeks), magnetic flux density (µT), and daily exposure time (hours/day) were the explanatory variables with adjustment for the study. We analyzed by sex. The P -value (P ) was defined as the probability of having observed our data (or more extreme data) when the null hypothesis was true. In multiple linear regression analyses of male and female rats, performed separately, we obtained estimates of the effect on relative body mass of study duration (coefficients 0.0225 and 0.0201, respectively; both P < 0.0001), magnetic flux density (coefficient 0.0002 for males, P < 0.0001; coefficient −0.0002 for females, P = 0.0015), and daily exposure time (coefficient 0.046 for

“…Using a sample of 56 adults, 30 males and 26 females, ages between 24 and 73 years in Urausu Hokkaido, Japan for seven consecutive days, Mitsutake et al (2005) found that blood pressure was lower for the days of enhanced amplitude of the Schumann resonance (see below) as compared with quiet day; subjective health and depression were not associated. Men had a higher blood pressure than women during periods of increased resonance amplitude.…”
