Rating (out of 5): 2

Salt, including Himalayan salt, is used to support or treat hypotension (low blood pressure) primarily due to its sodium content, which is well established in medical literature as a factor that raises blood pressure. The recommendation to increase sodium intake for patients with hypotension is supported by clinical guidelines and studies, as sodium increases blood volume and systemic vascular resistance, thereby elevating blood pressure. However, most scientific evidence pertains to sodium chloride in general, not specifically Himalayan salt, which is compositionally similar to regular table salt but contains trace minerals in negligible amounts. Himalayan salt does not possess unique properties that make it superior to regular salt for this purpose.

Scientific support for using salt to address hypotension is moderate, with evidence mainly drawn from clinical practice and physiological studies on sodium's effect on blood pressure. For example, guidelines for managing orthostatic hypotension often include recommendations for increased salt and fluid intake as a first-line intervention. However, the quality and quantity of controlled trials specifically evaluating salt supplementation for chronic hypotension are limited, and excessive salt intake carries risks, particularly for those with comorbidities such as heart or kidney disease. In summary, increasing salt intake is a scientifically recognized strategy to support blood pressure in cases of hypotension, but this applies to salt in general rather than specifically to Himalayan salt.
