Three factors that may increase blood pressure: a diet high in salt/sodium; chronic psychological stress; and a sedentary lifestyle combined with obesity.
Relationship between high BP and the circulatory system: blood pressure is a direct measure of the force blood exerts on artery walls as the heart pumps; when it stays elevated for a long time, the heart must work harder against that resistance, and the artery walls themselves can become damaged and less elastic over time, raising the risk of heart attack, stroke, and kidney damage.
Why high BP is called the "silent killer": it typically produces no obvious symptoms for years, so a person can have significantly elevated BP and feel completely normal, all while organ damage builds up silently -- often only discovered when a serious event (heart attack, stroke) occurs.
Five symptoms of high BP (when it does become symptomatic, often at very high readings): headaches, dizziness, blurred vision, chest pain, and shortness of breath. …
