Even minor blockages in the arteries can lead to a heart attack or stroke.
When we think about cardiovascular health, our attention often becomes overly focused on the heart. However, the heart cannot beat without the help of the rest of the body, particularly the arteries, writes Parade.
"Arteries are vital vessels of the heart, and understanding their role is the first step in protecting them. The heart not only pumps blood throughout the body but also relies on a constant supply of oxygen and nutrients delivered through the vessels on its surface known as coronary arteries," said cardiologist Nadim Gelu.
He describes healthy arteries as "wide, flexible, and smooth." They ensure free and efficient blood flow, allowing oxygen and nutrients to reach all necessary areas of the body, including the heart muscle.
"The heart muscle... relies on a constant supply of oxygen-rich blood to function properly and maintain strong and effective pumping ability. When the coronary arteries become stiff, narrow, or completely blocked, the heart muscle is deprived of the oxygen-rich blood it needs to function. This lack of oxygen diminishes the heart's pumping efficiency," Gelu explained.
The cardiologist noted that even minor blockages can lead to a heart attack or stroke. However, he stated that by giving up daily harmful habits in favor of healthier ones, one can keep the heart strong.
The publication notes that cardiologists recommend eliminating one specific daily harmful habit that can silently damage your arteries.
This habit is prolonged sitting. It is noted that this habit can have a devastating impact on the arteries and the cardiovascular system.
"Prolonged sitting reduces blood flow, especially in the legs, as the muscles do not contract to help return blood to the heart. This reduction in blood flow diminishes the healthy signals that maintain the flexibility and functionality of the arteries. Over time, the arteries lose their ability to expand normally and become more prone to stiffness and inflammation," explained cardiologist Neil D. Shah.
The article states that Shah refers to studies indicating that even one to two hours of continuous sitting can impair circulation and arterial function.
"A sedentary lifestyle is not just the absence of physical activity. It means that you spend most of the day sitting or inactive, often more than 8-10 hours a day," Shah noted.
The publication shared that a study published in the Journal of the American College of Cardiology in 2025 indicated that recommendations for physical activity may be insufficient if the rest of the day is spent sitting.
According to cardiologists, you do not need to change jobs that require prolonged sitting in front of a computer if you become more active. For example, walk for 10-15 minutes after meals. Also, try to take short breaks throughout the day to walk around. You can also take the stairs at work instead of the elevator, move while talking on your mobile phone, and so on.
