It’s quite normal for blood pressure to rise and fall throughout the day…
… however, when blood pressure stays elevated over time that it is called high blood pressure / hypertension.
So what is high blood pressure, and how is it measured?
Blood pressure is the force of blood against the walls of arteries.
When you have your blood pressure taken, you will note that the result is recorded as two numbers – the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats).
The measurement is written one above or before the other, with the systolic number on top and the diastolic number on the bottom.
For example, a blood pressure measurement of 120/80 mm Hg (millimeters of mercury) is expressed verbally as “120 over 80.”
Normal blood pressure is less than 130 mm Hg systolic and less than 85 mm Hg diastolic. Optimal blood pressure is less than 120 mm Hg systolic and less than 80 mm Hg diastolic.
If your blood pressure readings are consistently over 140/90 mm Hg or higher you have high blood pressure, another term for hypertension.
High blood pressure is a major risk factor for heart attack. Your arteries bring oxygen-carrying blood to the heart muscle. It is vital that the oxygen-carrying blood flows freely. If for whatever reason it is blocked, and your heart cannot get enough oxygen, then you are likely to experience chest pain, also known as “angina”.
Furthermore, if the flow of blood is blocked you may experience a heart attack.

What Causes High Blood Pressure?
The causes of high blood pressure vary. Causes may include narrowing of the arteries, a greater than normal volume of blood, or the heart beating faster or more forcefully than it should…
Who Can Get High Blood Pressure?

Why is High Blood Pressure Important?
High blood pressure is dangerous because it makes the heart work too hard, increasing your chance (or risk) of getting heart disease and/or kidney disease, and for having a stroke…
What is Systolic Blood Pressure?
Systolic pressure is the force of blood in the arteries as the heart beats.
What is Diastolic Blood Pressure?
Diastolic pressure is the force of blood in the arteries as the heart relaxes between beats.

Do You Have High Blood Pressure?
Then you need to read this book, by New Zealand author, Dr. David Lovell-Smith.
In this book, Dr. David Lovell-Smith describes how his patients successfully used diet, lifestyle changes, and Transcendental Meditation to bring their blood pressure down.
This book offers new hope and insight for those with high blood pressure but it is not for hypertensives alone. The knowledge which Dr. Lovell-Smith presents in his book is timely and relevant, and its exposition is long overdue.
