Older adults may face heightened orthostatic hypotension risk after mild sodium depletion; leaves open applicability to clinical populations.
Does age and mild sodium depletion affect the cardiovascular response to orthostasis in healthy subjects?
Healthy older individuals have decreased cardiovascular reserve, making them susceptible to orthostatic hypotension following mild sodium depletion.
Shannon et al. (1986) studied this question.
