Elevated blood pressure as a major indicator of higher health risks varies considerably around the globe. We examine whether the livability of the environment can account for part of this variation. Overly resource-poor and overly resource-rich countries are expected to be less livable, with elevated blood pressure as a likely result. Male and female populations from 120 countries indeed have higher blood pressures to the extent they have to cope with too few or too many rather than just enough environmental resources. In poorer countries, predominantly located in hotter climes, both genders have higher blood pressures in too difficult-and-expensive environments with more demanding summers or winters (too few resources), than in just-right environments with more temperate summers and winters (optimal resources). In richer countries, predominantly located in colder climes, both genders have higher blood pressures in too easy-and-cheap environments with more temperate winters and summers (too many resources), than in just-right environments with more demanding winters or summers (optimal resources). We conclude that the livability of climate-based demands and wealth-based resources have a heretofore hidden ecological impact on chronic health risks, which may shed novel light also on policies of climate protection and poverty reduction.
