Blood pressure is the pressure your blood exerts when it thrusts on the artery walls during circulation. Not many people, however, know that blood pressure keeps altering all the time. The way you sit, walk, exercise, and even eat may affect the blood pressure. Your mood and state of mind also alter your blood pressureThe Two Numbers In Your Blood Pressure ReadingsBlood pressure is measured in terms of the levels of mercury (mm of Hg). When your doctor examines your blood pressure level, there will be two numbers on the display: The first is the systolic pressure and the other is diastolic pressure.- The first reading or the systolic pressure is noted when the sound of the blood flow is first heard. - The second reading or the diastolic pressure is noted when the blood flow cannot be heardBoth these numbers determine your heart health and overall health. The Four Categories Of Blood Pressure ReadingsBlood pressure readings can be categorized into four, starting from normal to hypertension state which is stage 2. Like we said, blood pressure alters from time to time depending on the body activity, stress levels, lifestyle and food habits. This is one reason your doctor takes an average of at least three to four readings to determine heart health accurately. - A reading below 120/80 mm Hg is considered normal blood pressure range. Readings that are above or below this ideal range indicates that your heart is working extra hard work to pump the required blood to the rest of your body. - You have elevated blood pressure if the reading ranges 120–129/below 80 mm Hg. By making healthy lifestyle changes, you can bring down this reading. - Stage 1 high blood pressure, commonly known as hypertension, is associated with a reading range of 130–139/80–89 mm Hg. Your doctor might suggest definitive lifestyle changes along with medication.- Any reading above 140/90 is considered stage 2 high blood pressure. Your doctor will definitely suggest medication along with exercise and healthy lifestyle modifications. The blood pressure range for children may be slightly lower. Also, adults aged 65 years and over can be considered healthy with a blood pressure range of 130/99 mm Hg. However, it is again advisable to get yourself checked regularly.
