Does drinking water help with blood pressure? Many people are unaware that water is a vital part of our bodies. Our blood is made up of more than 70% water. So it only makes sense to drink plenty of water to maintain a healthy blood pressure level. Water intake is the secret sauce to a normal blood pressure level, and it’s something most people overlook. Blood pressure is measured in two parts: the systolic pressure (the force the heart exerts against the walls of our arteries), and the diastolic pressure, or the pressure between each heartbeat. A healthy blood pressure level is below 120/80 mm Hg.
The pressor effect of water is caused by water diluting the plasma in the blood vessels leading away from the duodenum. This diluting effect is the primary reason water lowers blood pressure, and it is associated with the sympathetic nervous system. It also causes the constrictor response, which prevents blood from pooling in the extremities. The American Red Cross studied water consumption to decrease the risk of fainting during blood donation. The drinking of 16 ounces of water reduced fainting responses by about 20%. Further, Julia McHugh studied water’s effect on mice to determine whether it can help reduce blood pressure.
Whether drinking water helps lower blood pressure depends on the level of blood sugar in the body and other factors, but water has proven to be one of the best beverages for lowering the pressure. Drinking water with added minerals is even more effective. Citrus juices are also good for blood pressure. The right kind of beverage to drink for people with high blood pressure depends on what you enjoy. You should consider adding some citrus juice or other flavoring to your water.
