High blood pressure seldom has no noticeable symptoms, which is why it is often known as "silent killer," the NHS said.
Left untreated, the situation – also known as hypertension – may increase the risk of stroke and heart attacks.
Some diet or lifestyle changes will help reduce your chances of high blood pressure.
Taking magnesium additives daily can be crucial to avoiding hypertension.
Adding magnesium to your diet may relax your blood vessels and reduce your blood pressure, Dr. Ronald Hoffman said.
It also increases arterial blood flow and can lower blood pressure from both systole and diastole, he said.
All men should seek about 300 mg of magnesium per day, while women should receive 270 mg per day, adding NHS.
Hoffman said, "Blood pressure generally varies in short days every day, but if it stays high, it is a risk of heart disease, stroke, and kidney disease.
"High blood pressure is all the more venomous because it is a silent killer and it does not cause any symptoms, at least when it is at an early stage at a moderate stage.
"It has long been known that magnesium relaxes the blood vessels and improves arterial blood circulation.
"It makes sense because it is a natural calcium channel blocker, similar to the antihypertensive drug class.
"In a recent study, magnesium addition showed little effect on blood pressure, with systolic and diastolic readings dropping by about two points."
The body needs magnesium to be the food we eat for energy and to preserve bone.
If supplements are not yours, you can add magnesium to your diet by eating green leafy vegetables, nuts or brown rice.
But you should notDo not take more than 400 mg of magnesium in one dayas it may cause diarrhea.
High blood pressure affects over 25 percent of all adults in the UK, said NHS.
Diagnosing early is very important because patients are more likely to develop some lethal complications.
The only way to know if you have a risk of getting blood pressure is to check your blood pressure.
But there are some obvious signs of a state of caution, including severe headaches, persistent nosebleeds and chest pain.
All British adults should check their blood pressure at least every five years.
