February- Healthy Heart Month...
Here's a tip for the week-
What is blood pressure?
Blood pressure is the force of blood against the walls of arteries.
Every time the heart contracts, blood not only rushes ahead through the vessels, but also presses against the walls. That pulse is the systolic pressure, the first number in your blood pressure reading.
When the heart relaxes between beats, the pressure eases too but only to a point. That is the diastolic pressure, the second number. The force of both pressures is measured by how high a pulsing artery can push a column of mercury in a blood pressure monitor.
