Blood pressure –everyone knows it shouldn’t be too high or too low, but that’s about it! In this article, we’re answering some interesting questions about blood pressure; what it is, why it matters, how to manage blood pressure issues, and more.
#1 – What is blood pressure?
Your heart is a sophisticated pump, pushing blood to our lungs and through our bodies through a massive network of veins, arteries, and capillaries. This network stretches through every organ, muscle, and nervous system, measuring an incredible 100,000kms in total! It takes an average of just 20 seconds for blood to circulate throughout the body, and it’s all thanks to the pressure created by the heart and maintained by the structure of the veins and arteries.
#2 – What is normal, healthy blood pressure?
When you’re at rest, your blood pressure should be between 90/60 mmHg and 140/90 mmHg. The higher number is your systolic blood pressure, or the pressure in your heart when it beats, and the lower number is your diastolic blood pressure, or the pressure in your heart when it rests between beats. This can be measured using a blood pressure cuff.
#3 – What is high blood pressure?
High blood pressure is anything over 140/90 mmHg. Your blood pressure can be high for several reasons, and not all of them are bad! For example, if you are running, playing sports, or dancing, your blood pressure will increase with your heart rate to supply your muscles with more oxygen and nutrients and boost your senses. This type of temporary, activity-induced high blood pressure is very healthy for the heart, which is why we’re all supposed to do around 60 minutes of moderate physical activity each day.
However, when your blood pressure is consistently high, even at rest, then it starts to stress out your heart and cause damage to the cardiovascular system. This increases the risks of heart attack, sudden cardiac arrest, heart disease, and other potentially deadly health conditions.
#4 – What can I do?
Luckily, there are quite a few ways you can control your blood pressure and keep it at a healthy level. This includes exercising regularly, choosing healthy homecooked meals over takeaways and ready meals loaded with salt and saturated fats, cutting down on sugary, salty, and processed foods, quitting smoking, and drinking plenty of water rather than fizzy drinks and alcohol. It doesn’t mean you have to entirely cut out all the foods you enjoy – unless you have a severe heart health condition and have been advised to do so by your doctor. For most people, making takeout a once-a-week treat and limiting portions of salty, high-calorie, and processed foods is enough to make a difference, especially if you add in some exercise!
#5 – What is low blood pressure?
Low blood pressure is anything under 90/60 mmHg. People who are very fit and healthy tend to have low blood pressure and it’s not often a problem for them. Your blood pressure can also drop if you overheat, become dehydrated, are pregnant, have recently donated blood, are using certain medications, or have an infection. In these instances, low blood pressure can lead to dizziness, fainting, fatigue, and blurry vision, and can cause falls, especially in elderly people.
