Sitting All Day and Walking Less May Raise Heart Health Risks, Doctors Warn

Spending most of the day sitting at a desk and getting little physical activity could increase several risk factors linked to cardiovascular disease, doctors have warned. Health experts say modern routines that involve long hours of sitting, limited walking and little exercise can gradually affect metabolic and heart health.

Doctors have distinguished between sedentary behaviour and physical inactivity, noting that the two can overlap but are not identical. Spending extended periods sitting does not directly mean that a person will develop a blocked artery. However, prolonged inactivity can contribute to conditions that increase cardiovascular risk.

The risk can be particularly relevant for people whose daily routine involves sitting for several hours at work and then spending additional time sitting at home. A lifestyle involving little walking or structured exercise may further reduce overall physical activity.

Doctors recommend breaking up long periods of sitting rather than relying only on a single workout during the day. Standing up and moving for around five minutes every 30 to 60 minutes can help introduce more activity into an otherwise sedentary routine.

Simple changes can also increase daily movement. Walking while talking on the phone, using stairs instead of lifts when practical and taking a walk after meals are among the measures suggested by health experts. Regular physical activity remains important as well. Activities such as brisk walking, cycling and swimming can help people maintain cardiovascular fitness and support overall metabolic health.

Experts emphasise that preventing cardiovascular disease involves addressing multiple risk factors rather than focusing on sitting alone. Maintaining a healthy weight, monitoring blood pressure and cholesterol, managing blood sugar and remaining physically active can all contribute to better heart health. Even brief, frequent breaks from sitting can help reduce the amount of time spent inactive.
