HOW MUCH WILL EXERCISE CONTROL MY BLOOD PRESSURE?

BBC Science Focus

|

July 2025

High blood pressure is a major health concern, increasing the risk of heart disease, stroke and kidney problems. As a GP, I'm often asked how to manage it, and my advice always includes exercise. But how much is enough?

HOW MUCH WILL EXERCISE CONTROL MY BLOOD PRESSURE?

A 2021 study followed over 5,000 adults for 30 years, shedding light on the ideal 'dose' of exercise for blood pressure control. The key takeaway? It's not just about the type or intensity of exercise, it's the total amount that matters. The research suggests that aiming for 30 minutes of moderate-intensity activity most days of the week can significantly help. This includes activities where you can still talk but feel your breathing quicken, such as brisk walking, cycling or even active housework.
