The Environment and Blood Pressure.

A host of environmental factors can significantly increase arterial blood pressure (BP) including cold temperature, high altitude, loud noises, and ambient air pollutants. Although brief exposures acutely elevate BP, over the long term, chronic exposures may be capable of promoting the development of sustained hypertension. Given their omnipresent nature, environmental factors may play a role in worsening BP control and heightening overall cardiovascular risk at the global public health level.
