With blood pressure we mean the pressure which comes on the walls of blood vessels, each time the heart contracts. The heart pumps 60 to 80 times per minute.Here, blood is pumped through arteries and veins. Thus, nutrients and oxygen to be transported through the body and be disposed of.
Pressure on artery walls
The upper pressure or systolic pressure is the pressure on the artery walls when there is a lot of blood flowing through the veins. So when the heart contracts or beats.
When the heart relaxes below, the pressure on the arteries decreases. This is called the under pressure or diastolic pressure. This pressure is denoted mercury (mmHg) in millimeter.
What is normal blood pressure? For a healthy person has a blood pressure of 120 over 80 (120/80) optimally. This is a top pressure of 120 mmHg, and under a pressure of 80 mmHg. The limits increase slightly as you get older. For example, a person over 80 may have a systolic pressure of 150-160.
The blood pressure is not always high. For some activities your body requires more nutrients and oxygen. The blood pressure can then be temporarily higher.For example, in sports, stress or fright. This does not necessarily mean you have high blood pressure.
When your blood pressure at rest is higher or equal to 140 over 90, then you suffer from hypertension or high blood pressure. In this case, there is constantly a higher pressure on the arteries and your heart has to work harder to pump blood. This is not a healthy situation for your cardiovascular system.
In some people, high blood pressure is more common. Elderly people often suffer from it. It can also run in families and in black people is more common.
An unhealthy lifestyle, for example, too much salt, alcohol, smoking and too little potassium and movement, may increase the risk. A healthy lifestyle can therefore contribute to high blood pressure .
How do you know if you have high blood pressure? This can not really control yourself because you find anything. The doctor can measure your blood pressure, possibly prescribe medication and advise you to adjust your lifestyle.
