It has been found that people who take just four hours a week of leisure time exercise have a dramatically reduced risk of developing high blood pressure. The more exercise you get, the less danger you are in. Four hours a week can help to bring a 19 per cent lower risk of developing the condition. Even doing between one and three hours of exercise can have a dramatic impact, where you can cut the chance of getting high blood pressure by 11 per cent. You could also be more protected against heart attacks and strokes- which are both linked to high blood pressure. So by doing exercise outside of work it can have a dramatic impact on your health!
