Does watermelon lower blood pressure? Expert answers

Blood pressure is the force of blood against the walls of your arteries. 

Arteries are the vessels that carry blood from your heart to the rest of your body. Your blood pressure naturally rises and falls during the day.

The human blood pressure is measured using two numbers, the first represents the systolic blood pressure, which indicates how much pressure is in your arteries when your heart beats.

While the second, the diastolic blood pressure, measures the pressure in your arteries between heartbeats. (i.e., when your heart rests between beats.)

The normal blood pressure number is 120 systolic and 80 diastolic, which is written as “120 over 80,” or “120/80 mmHg.”

High blood pressure (also called hypertension) occurs when these number (120 and 80) becomes higher (say 130 and 90) or more

When your blood pressure is high, the force of blood against the artery walls becomes too high.

Unfortunately, high blood pressure has no cure, therefore, managing it is the only solution available to man.

There are no warning indications or symptoms of high blood pressure, and many people are completely unaware that they have it.

Blood pressure and watermelon 

The only way to cure high blood pressure is by managing it, this can be achieved through several means.

High blood pressure can be managed through natural means and watermelon is one such natural food that is considered to be an effective blood pressure-lowering food.

Does watermelon lower blood pressure

So, does watermelon lower blood pressure? We find out.

Yes, watermelon lower blood pressure, watermelon is sweet and tasty but low in calories and high in fibre and nutrients that may help to reduce high blood pressure.

A study carried out on forty volunteered participants aimed to see how supplementing with watermelon extract for six weeks affected prehypertensive and hypertension people’s blood pressure and sympathovagal balance.

For 6 weeks, they were given 6g of watermelon extract. The researchers examined blood pressure and cardiac autonomic modulation.

Watermelon extract reduced systolic (137.8 3.9 to 126.0 4.0 mmHg, p 0.0001) and diastolic (79.2 2.2 to 72.3 2.0 mmHg, p 0.001) blood pressure significantly, 

This provides more proof that watermelon extract supplementation lowers systolic and diastolic blood pressure in prehypertensive and hypertensive people.

Watermelon is also loaded with an amino acid called L-citrulline which helps to improve blood circulation and lower systolic blood pressure.

The L-citrulline in it is converted to an amino acid called L-arginine in the body which helps in the production of nitric oxide which is a blood vessel dilator.

Nitric oxide has a dilating effect, it helps blood vessels to expand and lowers blood pressure.

The amino acid (citrulline) in watermelon increases vasodilation (The expansion of arteries or veins) which is linked to a reduction in blood pressure and an increase in blood flow. This helps to manage high blood pressure.

Watermelon is rich in lycopene which helps to reduce the thickness of artery walls in turn helps to lower high blood pressure.

According to a new study from the People’s Republic of China, getting enough lycopene regularly can help lower blood pressure, especially in individuals with moderately high blood pressure.

Watermelon has the right proportion of electrolytes which helps to maintain the blood pressure efficiently.

The potassium, magnesium and other acids found in watermelon help to keep the blood vessels healthy and maintain smooth blood flow.

Magnesium can also help to lower blood pressure by acting as a natural calcium channel blocker, boosting nitric oxide levels, and decreasing endothelial dysfunction.

Increasing magnesium consumption has been linked to lower blood pressure, particularly in hypertensive patients.

The L-citrulline compound in watermelon also helps in lowering LDL cholesterol or bad cholesterol while increasing good cholesterol (HDL) levels

Because high cholesterol causes fatty deposits in our blood vessels, which can clot and trigger a heart attack or stroke, eating watermelon helps to maintain a healthy heart.

Watermelon lowers blood pressure as a result of L-citrulline (in watermelon). L-citrulline assists the blood vessels in relaxing and can improve arterial function.

Research shows that consuming watermelon juice or eating watermelon as such has not only reduced systolic blood pressure but also improved blood flow and arterial function.

Citrulline, an amino acid found in watermelon, aids in the management of high blood pressure. 

Citrulline also help the body to produce nitric oxide, a gas that relaxes blood vessels and encourages flexibility in arteries. These effects aid the flow of blood, which can lower high blood pressure.

Watermelon extract decreased blood pressure in the ankles and brachial arteries in a study of persons with prehypertension or mild hypertension and obesity.

So, the answer to whether watermelon lower blood pressure is yes,

Therefore, if you are looking for a safe and natural way to reduce blood pressure then watermelon is a good option and better than most antihypertensive drugs.
