Blood Pressure Basics

Written by: Nancy Giges

Often wonder why high blood pressure is dangerous?  The answer is that it makes the heart work too hard, increasing the risk of certain adverse conditions. Optimal blood pressure for adults is below 120-over-80 (measured in millimeters of mercury). A reading at or above 140-over-90 is considered high. The higher number represents the pressure when the heart contracts and the lower when it rests.


Fact or Fiction?


1. People with high blood pressure should not
take certain types of over-the-counter cold
and flu medicines.


Fact: Some medications, particularly decongestants,
can increase blood pressure and interfere with blood
pressure medications.


2. A major cause of high blood pressure is stress.


Fiction: In 90% to 95% of high blood pressure
cases, the cause is unknown. However, health care
experts recommend keeping stress under control as
part of an overall healthy lifestyle regimen.


3. People with high blood pressure should avoid
hot tubs and saunas altogether.


Fiction: If used properly, people with high blood
pressure should be able to enjoy a sauna or hot tub
with certain precautions. For example, don’t alternate
between cold baths and a hot tub or sauna. It's
always a good idea to check with your doctor.


Tips for Keeping Blood Pressure Low
• Eat a low-salt, low-saturated-fat diet
• Get 30 to 60 minutes of exercise on most days
• Limit your alcohol intake
• Maintain a healthy weight


If lifestyle changes don’t lower your blood pressure, your doctor may prescribe medication.
