A cardiologist is sounding the alarm on a modern epidemic that most people ignore: the act of staying still. Dr Sanjay Bhojraj, a California-based specialist with over more than decades of experience in cardiovascular medicine, took to Instagram on April 1 to highlight a daily habit that he said significantly elevates the danger of life-threatening cardiac events.

The danger of ‘sitting for hours’
“This daily habit doubles your heart attack risk, and most people don’t think twice about it,” Dr Bhojraj shared in a blunt advisory. While many focus on diet or smoking, he argued that the lack of physical movement was a primary driver of heart disease in his clinical practice.
“After 20+ years, I’ve seen it all…and the one habit that shows up every time: people don’t move enough. Sitting for hours slows circulation, raises blood sugar, and increases clot risk. That’s how heart attack and stroke risk climbs,” Dr Bhojraj shared.
What should you do?
The cardiologist highlighted that the solution does not necessarily require a gruelling gym regimen, but rather a fundamental shift in how we approach our hourly routine. He advised: “Stand up every 30–60 minutes. Walk. Do a few squats. Move your body daily. It’s truly that simple.”
Global health data supports the warning
Dr Bhojraj’s observations are backed by data from the World Health Organisation (WHO). In its 2024 fact sheet, the WHO identified physical inactivity as one of the leading risk factors for mortality from non-communicable diseases.
The WHO reported that adults who do not meet recommended levels of physical activity have a 20 to 30 percent increased risk of death compared to those who are sufficiently active. It added that sedentary behaviour is a direct contributor to hypertension and obesity, both of which are primary ‘gateway’ conditions for cardiovascular failure.
Furthermore, a study cited by the WHO in 2022 highlighted that sedentary lifestyles are responsible for approximately $27 billion in annual direct healthcare costs globally, as physical inactivity leads to a surge in type 2 diabetes and heart disease.
Medical experts explain that prolonged sitting leads to ‘metabolic slowdown’. When the body remains stationary, the enzymes that break down fats (lipids) in the blood decrease. According to supporting cardiovascular reports, the relationship between sitting and heart health is clear: the modern environment — designed for desks and couches — is at odds with human biology.
