Blood Pressure UK explains: “Salt makes your body hold onto water. If you eat too much, the extra water in your blood means there is extra pressure on your blood vessel walls, raising your blood pressure.”
It says that as well as reducing the amount of salt you eat and having a generally healthy diet, you should cut back on alcohol, lose weight if you’re overweight, cut down on caffeine, and if you are a smoker you should stop smoking.
The BHF says physical activity can help reduce your risk of heart and circulatory disease and reduce blood pressure and cholesterol.
The NHS says: “Regularly drinking too much alcohol can raise your blood pressure over time.”
