Medical science doesn't understand what causes most cases of high blood pressure, so it's hard to say how to prevent it. Several factors may contribute to it.
Risk Factors That Can't Be Controlled
* Heredity. People whose parents or other close blood relatives have high blood pressure are more likely to develop it themselves.
* Race. African Americans are more likely to have high blood pressure than Caucasians, and it tends to occur earlier and be more severe.
* Increasing age. Blood pressure tends to increase with age, and occurs most often in people older than age 35. Men have a greater risk of high blood pressure than women until age 45. From age 45–54, the percentages of men and women are similar. After age 55, women are more likely to develop high blood pressure than men are.
Controllable Risk Factors
* Sedentary or inactive lifestyle. Try to get at least 30 minutes of moderate to vigorous physical activity on most days.
* Heavy alcohol consumption. Heavy and regular use of alcohol can increase blood pressure dramatically.
* Sodium (salt) sensitivity.
* Obesity and overweight.
