You should follow the DASH diet, an eating plan in adults with normal to high blood pressure.
Few clinical studies have determined that this eating plan results in better results in lowering the blood pressure than the anti hypertensive drugs could.
Actually, people that practice the DASH 2 diet, with Stage 1 hypertension had their blood pressure decrease as much or more than any anti-hypertensive medication had been able to lower it.
The DASH diet is low in fat, saturated fat, cholesterol, and sodium, and high in potassium, magnesium, and calcium.
And for exercise, you should start slow and work more physical activity into your daily routine.
Usually, it takes about one to three months for regular exercise to have an impact on your blood pressure.
Aerobic activity like climbing stairs, walking, jogging, bicycling and swimming, for at least 30 minutes every day, should be beneficial for lowering your blood pressure.
Best wishes!
