Mark asks: What are some good ways to lower my blood pressure without drugs? “High blood pressure” is defined as any systolic pressure (the top number) above 140 or diastolic (the bottom number) higher than 90. So let’s look at what we are trying to control and the best natural ways to lower blood pressure. However, it’s the environmental factors we can control which give us the opportunity to naturally control high blood pressure. When it comes to high blood pressure, a study published in the Annals of Internal Medicine in 2002 showed that exercise alone can not only reduce blood pressure in people with high blood pressure, but will also help in people with normal blood pressures.
