Blood Pressure: What the Numbers Mean and How to Lower Yours

High blood pressure shows up quietly. You may feel fine while your arteries are under stress. Knowing your numbers and what to do about them can prevent heart attacks, strokes, and kidney problems. This page collects useful tips, quick checks, and real steps you can use every day.

How to read your blood pressure

Blood pressure is two numbers: systolic over diastolic. Systolic (the top number) measures pressure when your heart pumps. Diastolic (the bottom number) measures pressure when your heart rests. A normal reading is about 120/80 mmHg. Elevated or high readings start above that—stage 1 often begins around 130/80. Numbers matter because risk rises as pressure climbs.

Don’t trust a single reading. Take two or three readings, one minute apart, after you’ve been sitting quietly for five minutes. Use a validated automatic cuff on your upper arm. Wrist devices can work but tend to be less accurate. If home readings are high, repeat them at different times and bring the log to your doctor.

Simple habits that lower blood pressure

Small changes add up fast. Drop salt gradually — aim for less than 2,300 mg a day and lower if your doctor says so. Eat more vegetables, fruit, whole grains, and lean protein. Try the DASH style diet: it’s been shown to reduce pressure in weeks. Move more: brisk walking 30 minutes a day most days helps. Even short walks after meals can lower readings.

Lose weight if you need to. For many people, every 10 pounds lost cuts blood pressure. Cut down on alcohol — one drink a day for women, up to two for men. Quit smoking: it raises pressure and speeds artery damage. Manage stress with simple practices like deep breathing, short walks, or brief stretching breaks. Sleep matters too; repeated poor sleep can push numbers up.

Medication is often needed and works well. Common types include ACE inhibitors, ARBs, calcium channel blockers, diuretics, and beta-blockers. Each drug class works differently; your doctor will pick the right one based on other health issues. Take medications exactly as prescribed and report side effects. If costs or access are a concern, ask about generic options or reputable online pharmacy sources that follow safety rules.

When to call your doctor? Get urgent help for very high readings (like 180/120 or higher) especially with chest pain, severe headache, shortness of breath, or vision changes. For persistent high readings, schedule a follow-up to adjust treatment. Regular home tracking plus annual or semi-annual checkups lets you and your doctor spot trends and act early.
