4 lifestyle changes that lower high blood pressure | Dr Sanjay Gupta

High blood pressure is the number one risk factor for deaths globally. But what if your blood pressure numbers were only part of that story? In this episode, we’re joined by leading cardiologist Dr Sanjay Gupta, who explains why blood pressure is not a disease, but often a scream for help. Together with ZOE’s Chief Scientist, Professor Sarah Berry, he explores when blood pressure is a harmless response to stress, food, or movement, and when it signals real, long-term damage. You’ll learn why blood pressure targets aren’t universal, why worrying can make things worse, and why quality of life matters as much as numbers. This episode also breaks down what you can do to lower your blood pressure. Not quick fixes. Not pills. But everyday lifestyle changes that address the root cause. If your blood pressure is your body sending a message, what might it be asking you to change?
