We analyze the results of daily laser Doppler flowmetry monitoring of blood microcirculation parameters in 9 healthy volunteers performed in 2006-2009. Dependence of microcirculation and BP parameters on geomagnetic activity was analyzed separately in each volunteer (the influence of ambient temperature was previously excluded). Significantly increased parameters of microcirculation in response to higher geomagnetic activity were found in 4 volunteers (44%) and elevated BP in 1 volunteer; in other cases, no reaction was detected. It was shown that individual sensitivity to geomagnetic activity is proportional to its mean level during the period of measurement. Since blood perfusion volume in tissues directly depends on peripheral vascular resistance, we can conclude that under conditions of high geomagnetic activity microvascular tone varies to a greater extent than the tone of major vessels.
我们分析了2006年至2009年对9名健康志愿者进行的每日激光多普勒血流仪监测血液微循环参数的结果。在每位志愿者中分别分析了微循环和血压参数对地磁活动的依赖性（先前已排除环境温度的影响）。4名志愿者（44%）的微循环参数在较高地磁活动时显著增加，1名志愿者血压升高；在其他情况下，未检测到反应。结果表明，个体对地磁活动的敏感性与其测量期间的平均水平成正比。由于组织中的血液灌注量直接取决于外周血管阻力，我们可以得出结论，在地磁活动强烈的情况下，微血管张力的变化程度大于主要血管的张力。
