Hypertension

Overview

Hypertension is a persistently elevated arterial blood pressure (i.e., high blood pressure). It is the leading cause of cardiovascular disease (CVD) and premature death worldwide (Mills et al., 2020). If untreated, hypertension can significantly raise the risk of CVD, stroke and vascular dementia (British Heart Foundation, 2019). It is estimated that just approximately 14.4 million adults (25%) in the UK have hypertension, with many individuals still undiagnosed (British Heart Foundation, 2019). A meta-analysis found that a 10mmHg reduction in systolic blood pressure reduced the risk of major CVD events by 20%, coronary heart disease (CHD) by 17%, stroke by 27%, heart failure by 28%, and death from all causes by 13% (Ettehad et al., 2016). Those with hypertension are usually less active than those without hypertension, and it has been widely accepted that an increase in physical activity is an effective lifestyle modification that can both prevent and reduce hypertension (Churilla and Ford, 2010; Fagard, 1999). 

Physical Activity & Hypertension

Being physically active is extremely good for our general health and wellbeing, and is promoted by the British Heart Foundation. There is a strong base of scientific evidence pointing towards a positive dose-response relationship between physical activity and a reduced risk of hypertension and associated diseases. This means that the more physical activity you can incorporate into your daily routine, the more you are doing to reduce your risk of hypertension. 

Increasing your physical activity is a key cornerstone of any lifestyle therapy aimed at preventing or treating hypertension. The primary benefit of physical activity for hypertension is a reduction in blood pressure. Blood pressure is usually presented as two numbers – systolic pressure, which is the top number, and diastolic blood pressure, which is the bottom number. Systolic blood pressure is measured as the heart beats, pumping blood around the body. Diastolic blood pressure is measured as the heart relaxes between each beat. 

The Benefits of Physical Activity for Hypertension

Physical activity has consistently been shown to reduce the risk of hypertension. The key benefits of physical activity for an individual with hypertension include:

  • A short-term reduction in systolic blood pressure post-physical activity, which can persist for up to 24-hours
  • Regular physical activity can lead to sustained reductions in blood pressure
  • Prevents blood vessels from narrowing further, and in some cases can lead to an increase in blood vessel diameter. 
  • Reduces the stiffness of blood vessels, allowing them to expand or contract depending on the situation
  • Improved blood flow around the body

Other benefits of physical activity for people with hypertension include:

  • Reduced oxidative stress – this can reduce the risk of neurodegenerative conditions such as Alzheimer’s and Parkinson’s
  • Reduced levels of basal inflammation – excess levels of basal inflammation can lead to an increased risk of suffering from chronic health conditions such as CVD, type 2 diabetes and a number of different cancers
  • Improved endothelial function – The endothelium is the inner lining of the blood vessels. Improving the function of the endothelium improves immune function, improves the transfer of nutrients from the blood to working muscles, and general blood flow around the body
  • Improved insulin sensitivity and insulin response – improves glucose control, which is particularly important to help manage or reduce the risks associated with type 2 diabetes
  • Improved psychological wellbeing
  • Improved quality of life

KiActiv® Value Proposition for Hypertension

KiActiv® Health is a digital therapy which aims to empower people with long term conditions and those on rehabilitation pathways to self-care at home using their personal everyday physical activity. It utilises a personalised, Mentor-guided digital service which aims to empower individuals to make sustainable behaviour change in the context of their health, capacity and environment. The KiActiv® Health service is available 24/7 and requires no visits to clinics or gyms. Physical activity is something that is often dreaded or feared, and there is a common misconception that for physical activity to be valuable it must be vigorous or exercise based. Imparting an understanding that physical activity is more than just exercise and sport, and that every move matters, is vital for empowering effective self-management. We aim to help people living with hypertension to improve the self-management of their condition by supporting them to optimise their everyday physical activity in the context of health
