Understanding Blood Pressure Numbers
Blood pressure is expressed as systolic/diastolic. Systolic (top number) is pressure when your heart beats. Diastolic (bottom number) is pressure when your heart rests.
Normal: Less than 120/80 mmHg
Elevated: 120-129 and less than 80
Stage 1 hypertension: 130-139 or 80-89
Stage 2 hypertension: 140 or higher or 90 or higher
The DASH Diet
DASH (Dietary Approaches to Stop Hypertension) emphasizes:
- Vegetables and fruits
- Whole grains
- Lean proteins
- Low-fat dairy
- Healthy fats
- Limited sodium, sugar, and saturated fat
Studies show DASH can lower blood pressure by up to 11 mmHg—comparable to some medications.
Sodium Reduction
Most Americans consume 3,400+ mg sodium daily; recommendations suggest 2,300 mg. Reducing sodium lowers blood pressure significantly. Focus on whole foods rather than processed products, which contain 75% of dietary sodium.
Read labels carefully—even seemingly healthy foods like bread and canned soup contain substantial sodium.
Physical Activity
Regular aerobic activity (150 minutes weekly at moderate intensity) reduces blood pressure by 5-8 mmHg. Resistance training 2-3 times weekly adds additional benefit.
Stress and Sleep
Chronic stress and poor sleep elevate blood pressure. Meditation, yoga, and breathing exercises reduce stress hormones. Prioritize 7-9 hours quality sleep nightly.
Weight Management
Each kilogram of weight loss reduces blood pressure by approximately 1 mmHg. Combined with other lifestyle changes, modest weight loss produces significant cardiovascular benefit.
Alcohol Moderation
Moderate alcohol consumption (up to one drink daily for women, two for men) is associated with heart health benefits. Excessive consumption raises blood pressure.
