Fight Hypertension

Sometimes reading tips to reduce blood pressure, drinking water is recommended. However, authority sites, including the National Heart, Lung and Blood Institute and the Mayo Clinic do not mention drinking low blood pressure, when discussing treatments and lifestyle should changes.

Why some articles say that the drinking water lowers blood pressure?

The idea that drinking water lowers blood pressure seems to come from the idea that if much water is consumed, the sodium is flushed from the body and thus pressure will drop.

After all, several classes of diuretics are very effective at Reduce the pressure. This function diuretics by an increase in the loss of sodium from the body and an increased quantity of urine. Both the loss of sodium from the blood and decreasing the blood volume result in decreased blood pressure.

So if drugs that effectively lower blood pressure in most people, work by increasing the volume of urine and the amount of sodium in the urine, then drink more water should do the same?

Unfortunately, there is a problem with this argument. To understand why it is necessary to understand that the body is very tightly controlled the levels of fluid and ions such as sodium and calcium. For optimal functioning, the agency has a wide range of processes that are in accordance many ions and fluid levels within a narrow range.

Diuretics law on parts of the system that control sodium. For example, thiazide diuretics to bind and inhibit a protein called "Na /Cl symporter (Na = sodium chloride Cl =) that the amount of sodium that is reabsorbed back into the blood from the urine, is formed. The result is that the body recovered less sodium from the urine, as it is formed, and the more sodium is lost in the urine and there is a slight increase in volume. So diuretics influence on the regulatory system and change a part of the this.

Water has no effect on the sodium or fluid control system, so it will not change the total amount of sodium in the urine, or change the blood volume. Drink more water increases the volume of urine as the body regulates fluid levels, the blood volume stable. In addition, the same amount of sodium (and other, etc.) in a graeren volume will cause the urine dilute.

Think more about the colour of urine. If this is not the case consumed much liquid , or there was a lot of sweat, there will be a small amount of urine with a strong yellow color (of Urobilin). When a person is well hydrated, there are more urine with a pale color. Same with sodium. In a healthy person , The graer is the volume of urine due to the increasing consumption of liquid, the lower the concentration of sodium.

So the bottom line is that generally increasing the amount of water consumed will not increase the amount of sodium lost blood, Blood pressure, it will not lowered.

In fact, drinking water can cause indeed a very short-term increase in blood pressure in some people, especially those with certain types of very low blood pressure. This is only temporary and has no long-term effects on the blood - Pressure.

Keeping hydrate is good for the health, but overhydration has no benefit for the reduction of blood pressure.
