A healthy range for blood pressure is typically defined as below 120/80 mm Hg. Readings above this range are categorized into various stages, such as elevated (120-129 systolic) and hypertension (130/80 mm Hg or higher). Maintaining blood pressure within this ideal range is crucial as it reduces the risk of heart disease, stroke, and other cardiovascular problems. Regular monitoring, a balanced diet low in sodium, regular physical activity, and maintaining a healthy weight can help keep blood pressure in check.
