Chest Pain When Coughing: Causes, Treatment

Q: How often should I check my blood pressure?

Healthy adults should check their blood pressure at least once a year. Check more often if you are over 40, have readings in the elevated range, or have diabetes, kidney disease or a family history of heart disease. If you take blood pressure medicines, your doctor may ask you to check at home daily for a while.

You check your blood pressure at a pharmacy or a health camp, and the screen says 132/84. Is that normal for your age? Should you worry? Many people ask the same question, because blood pressure numbers do change as we get older. High blood pressure (hypertension) affects more than a billion adults worldwide, and many of them don't know they have it, because it usually causes no symptoms.

In this guide, the doctors at UniClinic Health explain what your BP numbers mean, share a simple BP chart by age for adults and children, and tell you when a reading needs a doctor's attention.

What Do Blood Pressure Numbers Mean?

A blood pressure reading has two numbers, measured in millimetres of mercury (mmHg):

Systolic (top number) — the pressure in your arteries when your heart beats and pumps blood.
Diastolic (bottom number) — the pressure in your arteries when your heart rests between beats.

So a reading of 120/80 mmHg means a systolic pressure of 120 and a diastolic pressure of 80. Both numbers matter. If either one is high, your doctor will take note.

Normal Blood Pressure Range: The Standard Adult Chart

For adults aged 18 and above, doctors use the same healthy target at every age. The latest American Heart Association and American College of Cardiology guideline (2025) groups readings into these categories.

BP Category	Systolic (mmHg)		Diastolic (mmHg)
Normal	Less than 120	and	Less than 80
Elevated	120–129	and	Less than 80
High BP – Stage 1	130–139	or	80–89
High BP – Stage 2	140 or higher	or	90 or higher
Hypertensive crisis (seek care now)	Higher than 180	and/or	Higher than 120

In India, many doctors follow Indian and European guidelines, which diagnose hypertension at 140/90 mmHg or above. Either way, a reading below 120/80 mmHg is considered healthy for adults of all ages.

Blood Pressure Readings by Age

Blood pressure tends to rise slowly as we age. That's why average readings look different for a 25-year-old and a 65-year-old. But remember: an average is not the same as a healthy target. Below 120/80 mmHg is still the goal at every adult age.

Blood Pressure Chart by Age and Gender (Adults)

The table below shows average blood pressure readings for each age group, based on population data from the U.S. National Center for Health Statistics.

Age Group	Average BP – Men (mmHg)	Average BP – Women (mmHg)	Healthy Target (mmHg)
18–39 years	119/70	110/68	Below 120/80
40–59 years	124/77	122/74	Below 120/80
60 years and above	133/69	139/68	Below 120/80*

For older adults, your doctor may set a personal target based on your overall health, other conditions and medicines.

A few patterns stand out in this blood pressure chart by age and gender:

Younger women usually have lower BP than men of the same age.
After menopause, women's blood pressure rises faster. By 60 and above, women's average systolic reading is higher than men's.
The systolic (top) number keeps rising with age, while the diastolic (bottom) number often levels off or falls after 60. This happens because arteries become stiffer over time.

Blood Pressure Chart for Children and Teenagers

Children have naturally lower blood pressure than adults. Doctors don't use the 120/80 cut-off for young children. Instead, they compare a child's reading with charts for their age, sex and height (called percentiles). A reading below the 90th percentile is normal.

The ranges below give a rough guide to blood pressure readings by age in children.

Age Group	Systolic (mmHg)	Diastolic (mmHg)
Newborn (first 12 hours)	60–85	45–55
Infant (1–12 months)	80–100	55–65
Toddler (1–2 years)	90–105	55–70
Preschooler (3–5 years)	95–107	60–71
School-age (6–9 years)	95–110	60–73
Preadolescent (10–11 years)	100–119	65–76
Adolescent (12–15 years)	110–124	70–79

From age 13, doctors use the same categories as adults: below 120/80 mmHg is normal.? If your child's reading seems high, a paediatrician can check it properly with the right cuff size and percentile charts.

Why Does Blood Pressure Rise With Age?

Looking at any age group blood pressure data, you'll notice readings climb over the years. The main reasons are:

1. Stiffer arteries — Blood vessels lose their stretch with age, so the heart has to push harder.

2. Plaque build-up — Fatty deposits narrow the arteries over time, especially with high cholesterol.

3. Hormonal changes — Falling oestrogen after menopause raises BP in women.

4. Kidney changes — Ageing kidneys handle salt and fluid less efficiently.

5. Lifestyle over the years — Weight gain, less activity, stress and high salt intake add up.

Rising BP with age is common, but it is not harmless. Even in older adults, controlling blood pressure lowers the risk of heart attack, stroke and kidney disease.

Signs and Symptoms of High Blood Pressure

Most people with high BP feel completely fine. That's why it is often called the "silent killer." The only way to know your numbers is to measure them.?

Very high blood pressure may cause:

· Severe headache, especially at the back of the head

· Blurred vision

· Chest pain or a pounding heartbeat

· Shortness of breath

· Dizziness or confusion

· Nosebleeds

If your reading is above 180/120 mmHg along with any of these symptoms, seek emergency care immediately.

What Increases Your Risk of High Blood Pressure?

Age above 40
Family history of hypertension
Being overweight or obese
Eating too much salt, pickles, papad and packaged or fried foods
Little or no physical activity
Smoking, tobacco chewing and alcohol
Long-term stress and poor sleep
Diabetes, high cholesterol, kidney disease or thyroid problems

How to Measure Blood Pressure Correctly at Home

A single high reading does not mean you have hypertension. BP changes through the day. Follow these steps for an accurate reading:?

1. Avoid tea, coffee, smoking and exercise for 30 minutes before checking.

2. Sit quietly for 5 minutes, with your back supported and feet flat on the floor.

3. Rest your arm on a table at heart level and use a cuff that fits your upper arm.

4. Don't talk during the measurement.

5. Take two readings, one minute apart, and note both.

6. Check at the same time each day, morning and evening, for one week before your doctor's visit.

Tips to Keep Your Blood Pressure Healthy at Every Age

· Cut down on salt — Aim for less than 5 g (about one teaspoon) a day, including hidden salt in packaged foods.

· Eat more fruits, vegetables, whole grains and dal, and fewer fried and processed foods.

· Stay active — At least 150 minutes of brisk walking, cycling or yoga each week.

· Keep a healthy weight, especially around the waist.

· Quit smoking and limit alcohol.

· Manage stress with breathing exercises, meditation or hobbies, and sleep 7–8 hours a night.

· Get regular check-ups. Adults over 18 should check BP at least once a year, and more often after 40. A full body health check-up with a lipid profile, creatinine and HbA1c helps spot related risks early.

When Should You See a Doctor About Your Blood Pressure?

Book an appointment with a doctor if:

Your home readings are 130/80 mmHg or higher on several days
Your BP stays in the "elevated" range (120–129 systolic) despite lifestyle changes
You have diabetes, kidney disease, high cholesterol or a family history of heart disease
You are pregnant and your BP is higher than usual
Your BP medicines don't seem to be keeping your readings in range
Your child or teenager has a high reading at a school or routine check-up
You have frequent headaches, dizziness or a racing heartbeat

Go to an emergency department immediately if your BP is above 180/120 mmHg with chest pain, breathlessness, weakness on one side, difficulty speaking or vision changes.

Frequently Asked Questions (FAQs)

1. What is the normal blood pressure for my age?

For all adults aged 18 and above, a normal blood pressure is below 120/80 mmHg, whatever your age. Average readings do rise with age. For example, men aged 40–59 average about 124/77 mmHg, and women aged 60 and above average about 139/68 mmHg. These averages show what is common, not what is healthy. For children, normal BP is lower and depends on age, sex and height.

2. Is 130/80 normal for a 60-year-old?

A reading of 130/80 mmHg falls in the Stage 1 high blood pressure range under the AHA/ACC guideline, even at age 60. Under Indian and European guidelines, it is considered "high normal" or elevated. It is common at this age, but it is worth discussing with your doctor. Many people can bring it down with less salt, regular walking and weight control, and your doctor can decide whether you need medicine.

3. Is blood pressure different for men and women?

Yes, at different stages of life. Before about 50, women usually have lower blood pressure than men of the same age. After menopause, women's BP rises faster, and by age 60 and above their average systolic reading is often higher than men's. The healthy target of below 120/80 mmHg is the same for both.

4. What is a dangerously high blood pressure reading?

A reading above 180/120 mmHg is a hypertensive crisis. Wait five minutes and check again. If it is still that high, or if you have chest pain, breathlessness, severe headache, weakness, numbness, vision changes or difficulty speaking, go to the nearest emergency department immediately.

5. What is a low blood pressure reading?

Blood pressure below 90/60 mmHg is usually considered low (hypotension). Some healthy people naturally have low BP without any problems. But if low BP causes dizziness, fainting, blurred vision or tiredness, especially in older adults, you should see a doctor to find the cause.

6. How often should I check my blood pressure?

Healthy adults should check their BP at least once a year. Check more often if you are over 40, have readings in the elevated range, or have diabetes, kidney disease or a family history of heart disease. If you are on BP medicines, your doctor may ask you to check at home daily for a while.
