Blood Pressure and Your Health: Know Your Numbers Week 2021

The 6th-12th September 2021 is ‘Know Your Numbers!’ week. A week long campaign that raises awareness of high blood pressure, encouraging all UK adults to get a blood pressure check. But what exactly is blood pressure and what are the effects on our health?

What exactly is blood pressure?

Blood pressure is the pressure of blood within the arteries and is produced primarily by the contraction of the heart. We usually measure blood pressure through the large arteries in the upper left arm using a blood pressure cuff and either a stethoscope or machine and its measurement is recorded by two numbers. The first is measured after the heart contracts and is highest and is known as systolic pressure. The second is measured before the heart contracts and is lowest and is known as diastolic pressure.

What does systolic and diastolic mean?

Systolic pressure is the reading of your heart contracting and pumping the blood out to the body. The systolic reading is the top number on your blood pressure readings and should be the higher number as more force is generated by contraction than relaxation in a healthy heart.

Diastolic pressure is the pressure of the heart relaxing and refilling between beats. This is the time where blood re-oxygenates by filling with new blood from the lungs. Diastolic pressure is the bottom number on a blood pressure reading and should be a lower number than the systolic pressure reading.

What should my blood pressure reading be?

According to the NHS, the ranges for ideal blood pressure are:

  • Low blood pressure (hypotension): 90/60mmHg or lower
  • Ideal blood pressure: between 90/60mmHg and 120/80mmHg
  • Borderline high blood pressure: between 120/80mmHg and 140/90mmHg
  • High blood pressure (hypertension): above 140/90mmHg

The facts and figures

So, now that we’ve covered what blood pressure is, what are the essential statistics on high blood pressure in the UK?

According to Blood Pressure UK:

  • High blood pressure is the third biggest risk factors for all disease after smoking and poor diet
  • Around one in three adults in the UK has high blood pressure. In England, 31% of men and 26% of women have high blood pressure
  • Half of people with high blood pressure are not diagnosed or receiving treatment. In England alone, there are more than 5 million people that are undiagnosed
  • Every 10mmHg reduction in systolic blood pressure reduces the risk of major cardiovascular events by 20%
  • Each 2mmHg rise in systolic blood pressure is associated with a 7% increased risk of death from coronary heart disease and a 10% increased risk of death from stroke

Blood pressure associated health risks

The most common issue that people experience with their blood pressure is high blood pressure – also known as hypertension. This is when the heart is exerting too much force than is ideal to pump blood around the body. High blood pressure rarely has noticeable symptoms but when left untreated, it could increase a person’s risk of developing long term health problems such as heart attacks, kidney disease or strokes.

Regular blood pressure testing can highlight any abnormalities or changes to blood pressure over time.

The cause of high blood pressure can vary from person to person; however, some common causes include:

  • Aged 65+
  • Overweight
  • Of African or Caribbean descent
  • High stress levels
  • Lack of exercise
  • High alcohol or caffeine intake
  • Consuming too much salt
  • Not eating enough fruit and vegetables
  • Smoking
  • Poor sleep

However, it’s not all bad news!

Even if you’re diagnosed with high blood pressure, or are at risk of high blood pressure, it doesn’t mean that it must stay that way or that you will even develop it. The most common treatments for those with high blood pressure are lifestyle changes and/or medication.

By maintaining a healthy lifestyle, you can lower your risk and even reduce already high blood pressure. A healthy lifestyle is one that consists of; regular exercise or physical activity, reduced sedentary time, losing weight if overweight, not smoking, low/no alcohol, and a healthy balanced diet.

Where can I get my blood pressure tested?

At Healthy Performance, we carry out Onsite Employee Health Assessments, all of which include a blood pressure reading. Our team of qualified healthcare professionals can identify high and borderline high blood pressure readings and can provide recommendations for lifestyle changes or make GP referrals in urgent cases.
