Drinking Water and Blood Pressure Regulation
Effects of Plain Water Ingestion on Blood Pressure
Research shows that drinking plain water can have different effects on blood pressure depending on the population. In people with hypertension and diabetes, drinking 0.75–1 liter of water in the morning, in addition to standard medications, led to a significant reduction in both systolic and diastolic blood pressure over two months. Many participants achieved target blood pressure levels, suggesting that morning water ingestion may be a helpful lifestyle modification for blood pressure control in these patients .
However, in other groups, especially older adults and those with autonomic failure, drinking water can actually cause a temporary increase in blood pressure. This is due to a rapid activation of the sympathetic nervous system, which raises blood pressure for a short period after water intake. This effect is so strong in patients with autonomic failure that it is sometimes used as a treatment for low blood pressure (orthostatic hypotension) Jordan2000Shannon2002Jordan2005. In healthy young adults, this pressor response is not observed Jordan2000Jordan2005.
Influence of Water Mineral Content on Blood Pressure
The mineral content of drinking water also plays a significant role in blood pressure regulation. Studies in both animals and humans have found that water enriched with calcium and magnesium can help lower blood pressure or prevent it from rising, especially in those with a tendency toward hypertension Lin2023Иванова2017Naser2019. In animal studies, strontium in water also reduced blood pressure by affecting certain biological pathways and reducing inflammation .
Conversely, high sodium (salt) content in drinking water is linked to higher blood pressure and increased risk of hypertension. In coastal regions where drinking water is often salty, reducing sodium levels in water led to lower blood pressure and a reduced risk of hypertension 6Scheelbeek2017. On the other hand, sodium bicarbonate-rich water (with less sodium chloride) may have a mild blood pressure-lowering effect, especially when combined with a low-salt diet .
Special Water Therapies and Blood Pressure
Some studies have explored unique water therapies, such as drinking water that has been recited over with religious texts. In one study with elderly individuals with hypertension, this practice was associated with a significant reduction in blood pressure, though the mechanism is unclear and may involve psychological or placebo effects .
Conclusion
Drinking water can influence blood pressure, but the effect depends on the amount, timing, individual health status, and especially the mineral content of the water. For people with hypertension and diabetes, regular morning water intake may help lower blood pressure. Water high in calcium and magnesium may also be beneficial, while water high in sodium can raise blood pressure. In some cases, drinking water can cause a temporary increase in blood pressure, particularly in older adults or those with certain medical conditions. Overall, the relationship between water intake and blood pressure is complex and influenced by multiple factors Rathod2023Noviati2023Jordan2000+7 MORE.
