Blood : Blood pressure normally varies throughout the day. A single reading that is high does not mean you have high blood pressure. Recording your blood pressure at home and at work may provide additional information. Once blood pressure rises above 115/75 mm hg, the risk of cardiovascular disease begins to increase. Home blood pressure monitoring can help you keep closer tabs on your blood pressure. Home blood pressure monitors are widely available, and you don't need a prescription. If your blood pressure is under control, you may be able to make fewer visits to your doctor if you monitor your blood pressure at home. You can help keep your blood pressure from being high with diet and other measures. The dietary approaches to stop hypertension (dash) diet emphasizes fruits, vegetables, whole grains and low-fat dairy foods. Maintain a healthy weight, don’t smoke, restrict salt, exercise, avoid stimulants and excess caffeine, reduce stress to the degree possible, and consider meditation/relaxation. Here is a link to the dash diet.
