对太阳生物学和相关领域的越来越多的研究揭示了空间气象因素和陆地生物学之间的无数潜在关系。此外，许多研究表明，各种疾病的发病率与心血管功能的许多方面具有周期性。目前的研究检查了1979年至2009年加拿大与高血压疾病相关的年度死亡率的周期性和与一系列太阳物理参数的线性关系。分析表明，空间天气和高血压死亡率之间存在一些显著的滞后相关性，太阳风血浆β被认为是这些相关性的可能来源。地磁活动和高血压病死率也有相似的周期。高血压死亡率以9.6年为周期长度的显著节律，而地磁活动符合10.1年的周期。死亡率与空间天气的交叉相关图显示，该周期为10.67年，与所研究时间段的平均10.6年太阳周期长度一致。对进一步的量化和潜在的影响进行了讨论。
Increasing research into heliobiology and related fields has revealed a myriad of potential relationships between space weather factors and terrestrial biology. Additionally, many studies have indicated cyclicity in incidence of various diseases along with many aspects of cardiovascular function. The current study examined annual mortality associated with hypertensive diseases in Canada from 1979 to 2009 for periodicities and linear relationships with a range of heliophysical parameters. Analyses indicated a number of significant lagged correlations between space weather and hypertensive mortality, with solar wind plasma beta identified as the likely source of these relationships. Similar periodicities were observed for geomagnetic activity and hypertensive mortality. A significant rhythm was revealed for hypertensive mortality centered on a 9.6-year cycle length, while geomagnetic activity was fit with a 10.1-year cycle. Cross-correlograms of mortality with space weather demonstrated a 10.67-year periodicity coinciding with the average 10.6-year solar cycle length for the time period examined. Further quantification and potential implications are discussed.
