What is blood pressure?

Posted by Mark Hamilton on

Blood Pressure 

Definitely an area of concern with many of my customers. There are certainly lifestyle adjustments we can take into account , along side some excellent supplements that would be beneficial.

Blood pressure refers to the pressure of your blood in your arteries. If the pressure is too low then you may struggle to pump adequate levels of oxygen and nutrients around the body which can cause light headedness and fainting, too high then over time this may cause the heart to enlarge and become less efficient at pumping. Long term hypertension increases the risk of heart attacks and strokes. 

There are a number of lifestyle modifications you can make to reduce high blood pressure such as reducing salt and alcohol intake[i], increasing physical activity[ii], losing weight[iii] and incorporating high amounts of berries[iv] and green tea[v] into your diet.

The essential mineral and electrolyte potassium has been shown to reduce blood pressure[vi]. A systematic review looking into the effect of increased potassium intake on blood pressure found a significant reduction in levels with a 24% decreased risk of stroke.[vii] In addition, magnesium, another essential mineral has shown to aid in the reduction of blood pressure. A meta-analysis found dose dependent reduction in blood pressure with magnesium supplementation.[viii]

Lifestyle Tips

Eat well: A healthy diet can help lower your risk of developing coronary heart disease and prevent weight gain, reduce your risk of diabetes and hypertension. Aim to eat plenty of fruit and vegetables to ensure a high fibre intake which has inversely been associated with heart disease[ix]. Limit processed foods as well as those rich in sodium and sugar.

Get Active: Physical activity can help reduce your risk of heart and circulatory disease. It can also help you control your weight and reduce blood pressure. Make exercise a part of your daily routine.

Maintain a healthy weight: Research shows that reaching and keeping to a healthy weight cuts your risk of heart and circulatory diseases because it helps prevent and manage conditions like high blood pressure and type 2 diabetes that put you at greater risk of coronary heart disease.

Quit smoking: Smokers are almost twice as likely to have a heart attack compared with non-smokers. If you smoke, stopping is the single most important step you can take to protect the health of your heart.

Reduce Stress: Although stress is not a directly a risk factor for heart and circulatory diseases, but it's possible that it may contribute to overall risk level. Change your lifestyle in a positive way can help you feel better able to cope with the demands put onto you. A balanced diet, meditation and regular physical activity can help you cope with stress.

Reduce Alcohol: Drinking more than the recommended amount of alcohol can have a harmful effect on your heart and general health. Alcohol is also high in calories so it can lead to weight gain. Current recommendations are not to drink more than 14 units per week and have some alcohol-free days within the week.
