The pressure of blood pushing against the walls of your arteries
Blood pressure normally rises and falls throughout the day
Systolic blood pressure
Measures the pressure in your arteries when your heart beats
Diastolic blood pressure
Measures the pressure in your arteries when your heart rests between beats
Normal blood pressure
Less than 120/80 mmHg
High blood pressure (hypertension)
Blood pressure that is higher than normal
The higher your blood pressure levels, the more risk you have for other health problems, such as heart disease, heart attack, and stroke
Blood pressure levels
Normal: systolic less than 120 mmHg, diastolic less than 80 mmHg
Elevated: systolic 120-129 mmHg, diastolic less than 80 mmHg
High blood pressure (hypertension): systolic 130 mmHg or higher, diastolic 80 mmHg or higher
High blood pressure usually has no warning signs or symptoms, and many people do not know they have it
Causes of high blood pressure
Unhealthy lifestyle choices, such as not getting enough regular physical activity
Certain health conditions, such as diabetes and having obesity
Can also happen during pregnancy
High blood pressure
Can damage your heart, brain, kidneys, and eyes
High blood pressure
Can lead to heart attack, heart disease, stroke, and kidney disease
There's only one way to know if you have high blood pressure: Have a doctor or other health professional measure it
Things that can help prevent or manage high blood pressure
Getting at least 150 minutes of physical activity each week
Not smoking
Eating a healthy diet, including limiting sodium (salt) and alcohol
Keeping a healthy weight
Managing stress
Taking medicine (if needed)

Blood pressure
The strength of the 'pushing' of blood against the artery walls as the heart pumps blood around the body
Blood pressure changes throughout the day
Blood pressure is lower when you're asleep or relaxing and goes up when you move around
Blood pressure can also be increased by stress or extreme emotions and stimulants like nicotine or caffeine
High blood pressure (hypertension)
When your blood pressure is regularly higher than recommended levels
High blood pressure can lead to damaged arteries and increase your risk of heart attack, stroke, heart failure, kidney and eye damage
How blood pressure is measured
1. A cuff (thick band) is put over your arm, attached to a machine which measures the pressure inside your arteries
2. The cuff tightens and then slowly loosens again
3. The machine gives a blood pressure reading
Blood pressure reading
Contains two numbers - the first (top) number is the pressure when your heart beats (systolic pressure), the second (bottom) number is when your heart relaxes (diastolic pressure)
For most people an ideal blood pressure is 120/75, or lower
If you're already on high blood pressure medication, your ideal blood pressure will be 130/80 or below
Home blood pressure monitoring
Measuring your blood pressure on an ongoing basis at home using your own blood pressure monitor
