Drinking salty mineral water doesn't raise blood pressure
Blood Pressure Stability and Plasma Aldosterone Reduction: The Effects of a Sodium and Bicarbonate-Rich Water - A Randomized Controlled Intervention Study

Surprising Findings
Increased sodium intake from mineral water did not raise blood pressure—even though participants consumed 1,500–2,000 mL daily of high-sodium water.
Public health guidelines warn that excess sodium raises BP; this study shows that in healthy adults, a large sodium load from water alone didn’t trigger that response.
Practical Takeaways
If you're healthy, drinking 1.5–2L/day of high-sodium, high-bicarbonate mineral water may not harm your blood pressure—and might even help reduce calcium loss.

Eating more salt won't make your blood pressure stay high if you're otherwise healthy.
Drinking a special kind of mineral water with lots of sodium and bicarbonate for a month doesn’t raise your blood pressure, even though you’re taking in more salt than usual.
Drinking this special mineral water makes your body produce less of a hormone called aldosterone, which helps control blood pressure — and this effect is stronger than with regular mineral water.
Even though people urinate out more salt after drinking this mineral water, their blood pressure doesn’t go up — meaning the body’s salt removal system works fine without raising BP.
Drinking this mineral water makes you pee out more salt and less calcium — which might help protect your bones and kidneys.
