Blood Pressure
We’ve probably all had our blood pressure checked at some point but what exactly is blood pressure and why is it so important for the health of our hearts?
What is blood pressure?
Blood pressure is a measure of the force blood exerts on the arteries as it’s pumped around the body. There are two measures of blood pressure:
-
Systolic pressure - the pressure the blood exerts on the arteries when the heart beats
-
Diastolic pressure - the pressure the blood exerts on the arteries when the heart relaxes between beats.
How is blood pressure measured?
Blood pressure is measured in units called millimetres of mercury, usually shortened to mmHg. The first figure is the systolic measurement and the second figure is the diastolic measurement, so it’s systolic over diastolic - e.g. 124/80.
What’s a healthy blood pressure measurement?
The ideal blood pressure measurement is systolic blood pressure of 120 mmHg and diastolic blood pressure of 80 mmHg, so 120/80 mmHg. However your blood pressure depends on many factors, including your age and family history. If your blood pressure is above this, there are lots of manageable changes to your diet and lifestyle which may help to manage it and bring it down to a healthier level. However if you are concerned about your blood pressure, you should always talk to your doctor first.
How can you tell if your blood pressure is outside the normal range?
It’s often difficult to tell if you’ve got high blood pressure, as there are rarely any symptoms. That’s why it’s important that you have regular check ups with your doctor, nurse or pharmacist.
Can your blood pressure go too low?
Most experts agree that reductions in blood pressure can only be beneficial as long as they’re not sudden or dramatic. If you have any concerns about your blood pressure, make sure to speak to your doctor.
What lifestyle changes can you make to control your blood pressure?
Simple, but positive steps that can help include losing weight, getting more exercise, reducing your salt intake, stopping smoking, moderating your alcohol intake, eating a healthy diet with plenty of fresh vegetables, fruit and low-fat dairy products and reducing stress.
