›› Normal Blood Pressure Values
There has been a lot
of talk lately about blood pressure. Blood pressure is the force of
movement of blood throughout the arterial and vascular circulatory
systems. Oxygenated blood sent rushing into the arteries after the left
ventricle in the heart contracts. The blood vessels accommodate blood
flow to maintain normal blood pressure values. When the vessels become
narrow, the amount of blood flow is restricted causing a rise in blood
pressure.
Blood pressure readings are measured by two different values, the
systolic and diastolic pressures. After the heart contracts, it has
forced blood into the arteries at its greatest strength. This is the
systolic pressure. As the pressure in the arteries relaxes, the
pressure decreases. This is called the resting, or diastolic pressure.
When represented in written form, such as 120/80, the top number is the
systolic reading, and the lower number is the diastolic. This blood
pressure reading, 120/80, is the average measurement of a wide range of
readings, representing normal blood pressure values. The value that
concerns most is the diastolic reading. When it is consistently higher
than 80, hypertension is present. Pressure fluctuates naturally
throughout the day with activity, rest, excitement, emotions, stress,
etc., this is normal and does not necessarily indicate that anything is
wrong.
When blood pressure readings are consistently 140/90 or higher, even at
periods of rest, hypertension is present. Readings over 160/95 are of
concern, because this is considered the danger zone. Hypertension is
called the silent killer because it has no symptoms until the pressure
is extremely high. According to the American Heart Association, 68
million Americans have one or more forms of heart or blood vessel
disease. There is no cure for hypertension; it must be medically
managed with prescribed antihypertensive agents, combined with diet and
exercise.
There are quite a few factors that contribute to altering normal blood
pressure values creating hypertension. As we age, the arteries are not
as elastic and restrict blood flow, also known as "hardening of the
arteries" or arteriosclerosis. Other factors are family history of
hypertension and heart disease, use of oral contraceptives, alcohol,
illegal substances, weight gain, sedentary lifestyle, smoking,
stress-related issues, and a high fat, high sodium diet. This list of
course, is not all inclusive.
Have no fear; it is possible to maintain normal blood pressure values
if you have hypertension. Regular visits with your physician are of
great importance, as well as complying with prescribed medication
regimens, regular aerobic exercise, and maintaining a healthier diet.
By engaging in regular physical activity, we feel better, because our
bodies are more efficient. Aerobic activities such as walking, running,
swimming, and dancing, will not only allow you to be more fit
physically, mentally, and spiritually, but your blood pressure will be
lower as well. Diets low in sodium and high amounts of fat also work to
lower blood pressure. Whole grains, fruits, and vegetables are very
plentiful and have a variety of uses, providing you with a smorgasbord
of healthy food choices-so enjoy!
