The Physical Activity: Cardiovascular Health Intersection

The heart is a muscle. The heart health is interconnected with exercise. The heart is a pumping organ which pumps more blood when you exercise, which improves its functioning capacity and improves its strength.

The World Health Organisation and the American Heart Association recommend:

1. At least 150 minutes per week of moderate activity (like brisk walking), or

2. 75 minutes per week of vigorous activity (like jogging),

3. Plus muscle-strengthening activities twice weekly

How Physical Activity Helps Your Heart

1. Lowers Blood Pressure

When the heart pumps blood continuously, the blood vessels relax and are able to allow blood to flow easily through the vessels.

2. Improves Cholesterol

Exercise can:

• Raise “good” HDL cholesterol

• Lower “bad” LDL cholesterol

• Lower triglycerides

• Improve overall cholesterol balance

3. Controls Blood Sugar

Blood sugar levels are controlled by insulin levels. Regular exercise helps to regulate insulin levels and improve overall blood sugar levels. Reduction in blood sugar levels reduces the damage to the blood vessels, which in turn reduces the risk of heart diseases.

4. Reduces Inflammation

Long-term inflammation could result in heart diseases. Regular, consistent exercise could help reduce inflammatory changes and help promote heart health.

5. Strengthens the Heart Muscle

With consistent activity:

• The heart pumps more efficiently

• Resting heart rate may decrease

• Circulation improves

Physical Activity Lowers Risk of Heart Disease

People who are physically active have a lower risk of:

• Heart attacks

• Stroke

• Heart failure

• Sudden cardiac death

Importantly, the biggest benefit happens when someone moves from being completely inactive to doing even modest activity.

Sitting Too Much Is a Risk

Long periods of sitting can negatively affect heart health, even if you exercise regularly. Try to:

• Stand up every 30–60 minutes

• Take short walking breaks

• Use stairs when possible

Small movement breaks matter.

What Counts as Physical Activity?

You do not need to exercise aggressively. Examples include:

• Brisk walking

• Cycling

• Swimming

• Dancing

• Gardening

• Climbing stairs

• Playing with children

The ending note

Physical activity is one of the most effective tools for protecting your heart. It lowers blood pressure, improves cholesterol, controls blood sugar, reduces inflammation, and strengthens the heart muscle.

You do not need extreme workouts. Regular, moderate movement when done consistently can significantly reduce your risk of heart disease and improve overall well-being.
