Specifically, coconut water helps the body excrete sodium through urine. When sodium is excreted, blood volume decreases slightly, and pressure on the blood vessels also decreases. Therefore, the amount of potassium in coconut water can counteract the blood pressure-raising effects of sodium, according to the health website Healthline (USA).

Coconut water is rich in potassium, which has a mild blood pressure lowering effect.

However, one thing to note is that you should not add salt to coconut water. This is because salt is rich in sodium. It is better to choose fresh coconut water.
Coconut water not only provides potassium but also has a mild diuretic effect, which means it promotes water excretion through the kidneys. This effect can help reduce the volume of blood inside the blood vessels, thereby reducing the pressure in the vessels and helping to lower blood pressure.
However, if you drink coconut water combined with diuretics, it can cause dehydration, sudden drop in blood pressure, and even electrolyte disturbances. Therefore, people with high blood pressure who are drinking coconut water should monitor their urine output and signs of dehydration such as dry mouth and dizziness to ensure the diuretic effect and not cause negative effects on health.
Some studies have shown the blood pressure-lowering effects of coconut water. Specifically, in a study published in the International Journal of Medical Research & Health Sciences , scientists discovered that drinking 300 ml of coconut water daily for 6 weeks regularly helps improve blood pressure in people with high blood pressure. Specifically, systolic blood pressure decreased by an average of 10.5 mmHg, while diastolic blood pressure decreased by 6.8 mmHg.
Many studies have shown that drinking about 300 ml of coconut water per day for several weeks has been proven to effectively reduce blood pressure. However, patients should not overuse coconut water.
Coconut water is not a substitute for medicine or water.
Coconut water should only be used as a supplement and not as a substitute for medication or water. In particular, coconut water should not be used as a treatment for high blood pressure. Drinking too much coconut water can lead to hyperkalemia. Symptoms of hyperkalemia include muscle weakness, numbness, tingling, slow heartbeat, anxiety or fainting.
To take advantage of the benefits of coconut water and avoid unwanted side effects, people should start drinking coconut water in small amounts, such as 100-200 ml/day. If you feel okay, you can drink 300 ml/day, according to Healthline .
