💓 Under Pressure: What You Need to Know About Blood Pressure

When you visit your doctor, one of the first things they check is your blood pressure. It's a simple test — a cuff on your arm, a few seconds of silence, and then two numbers appear. But behind that routine reading lies one of the most critical indicators of your overall health.

In this issue, we break down what blood pressure really is, why it matters, how to interpret your numbers, and — most importantly — what you can do to keep it in a healthy range.

What Is Blood Pressure?

Blood pressure is the force that circulating blood exerts on the walls of your arteries — the vessels that carry blood from your heart to the rest of your body. It’s measured using two numbers:

• Systolic pressure (the top number): The pressure when your heart beats and pushes blood out.

• Diastolic pressure (the bottom number): The pressure when your heart rests between beats.

It’s measured in millimeters of mercury (mm Hg) — a legacy from when mercury-filled columns were used to measure pressure.

Example:

A reading of 120/80 mm Hg means your systolic pressure is 120 and your diastolic is 80.

What’s Considered Normal?

According to guidelines from the American Heart Association and Centers for Disease Control and Prevention (CDC):

Note: One high reading does not necessarily mean you have high blood pressure. Diagnosis is based on consistent readings over time.

Why Does Blood Pressure Matter?

High blood pressure — also called hypertension — is often called a silent killer. Why?

Because it usually has no symptoms until serious damage has occurred. Many people live with high blood pressure for years without knowing it.

Unchecked high blood pressure damages the arteries, heart, brain, kidneys, and eyes. It dramatically increases your risk of:

• Heart disease

• Stroke

• Kidney failure

• Vision loss

• Cognitive decline (dementia, Alzheimer's)

Conversely, very low blood pressure (hypotension) can also be dangerous, leading to dizziness, fainting, and shock in severe cases.

What Causes High Blood Pressure?

Several factors can contribute to high blood pressure. Some are modifiable, others are not:

✅ Modifiable Risk Factors:

• Unhealthy diet, especially high in sodium

• Lack of physical activity

• Obesity

• Excessive alcohol intake

• Smoking

• Chronic stress

• Poor sleep quality

🚫 Non-Modifiable Risk Factors:

• Age (blood pressure tends to rise as you age)

• Genetics and family history

• Race/ethnicity (e.g., African Americans are at higher risk)

• Underlying medical conditions (like diabetes or kidney disease)

How Is Blood Pressure Measured Correctly?

To get an accurate reading:

• Sit calmly for at least 5 minutes before the measurement.

• Keep your back supported and feet flat on the floor.

• Rest your arm on a table so it’s at heart level.

• Avoid caffeine, exercise, or smoking 30 minutes beforehand.

• Don’t talk during the measurement.

Tip: Take multiple readings at different times of day, especially if you're monitoring at home.

When Should You Be Concerned?

Any consistent readings above 130/80 mm Hg should prompt a conversation with your healthcare provider. Especially if you have other risk factors (like diabetes or high cholesterol), even "elevated" blood pressure can be serious.

Also seek immediate medical attention if you get a reading of 180/120 mm Hg or higher and have symptoms like:

• Chest pain

• Shortness of breath

• Vision changes

• Numbness or weakness

• Severe headache

Lifestyle Tips to Control Blood Pressure Naturally

Before medications (and even alongside them), lifestyle changes can make a major difference. Here's how:

🥗 Eat Smart

• Emphasize fruits, vegetables, whole grains, lean proteins.

• Choose DASH Diet (Dietary Approaches to Stop Hypertension).

• Cut back on salt — aim for <2,300 mg per day (less than 1 teaspoon).

• Avoid processed foods, fast food, and canned soups (often loaded with sodium).

🧘 Manage Stress

Chronic stress keeps blood pressure high. Practice:

• Deep breathing

• Meditation

• Yoga or stretching

• Journaling or therapy

• Time in nature

🏃‍♀️ Move Your Body

• Aim for 150 minutes/week of moderate exercise (e.g., brisk walking).

• Even short bouts (10–15 minutes) add up.

🛏 Prioritize Sleep

• 7–9 hours of quality sleep per night is key.

• Treat sleep apnea if present.

🍺 Limit Alcohol

• Men: no more than 2 drinks/day

• Women: no more than 1 drink/day

🚭 Don’t Smoke

• Smoking narrows blood vessels and spikes blood pressure.

• Quitting has near-immediate cardiovascular benefits.

When Are Medications Needed?

If lifestyle changes aren't enough, your doctor may recommend medication. Common types include:

• Diuretics (help eliminate excess salt and water)

• ACE inhibitors (relax blood vessels)

• Beta-blockers (slow heart rate)

• Calcium channel blockers (widen arteries)

Medications may be long-term. Always take them exactly as prescribed. Never stop without medical advice.

Should You Monitor Blood Pressure at Home?

Yes — especially if you have known high blood pressure or are at risk. Home monitors are widely available, affordable, and easy to use.

Look for one that is:

• Automatic with upper-arm cuff (more accurate than wrist or finger devices)

• Clinically validated

• Able to store readings or connect to a phone app for tracking

Regular tracking helps you and your doctor spot trends and make timely changes.

Myths vs. Facts

Let’s clear up a few common misconceptions:

Myth: “I feel fine, so my blood pressure must be normal.”
Fact: High blood pressure often has no symptoms. Only a measurement can tell.

Myth: “Only older people need to worry about blood pressure.”
Fact: Hypertension is rising in young adults due to obesity, stress, and poor diet.

Myth: “Once my numbers improve, I can stop treatment.”
Fact: Blood pressure can rise again. Long-term management is essential.

Final Thoughts: Take Pressure Seriously

Blood pressure may seem like just another number, but it tells a powerful story about your cardiovascular health. The good news? It’s one of the most preventable and manageable risk factors for heart disease and stroke.

A few small changes today can lead to major health benefits tomorrow. Whether it's tweaking your diet, walking more, or simply checking your readings regularly — every step counts.

Stay informed. Stay proactive. And don’t let pressure sneak up on you.

🫀 Your heart will thank you.
