Prolonged sitting is no longer just a lifestyle habit-it significantly affects longevity and health. Research shows that extended sedentary behaviour substantially raises the risks of heart disease and death, and exercise alone is not enough to compensate. Experts advise standing and moving around every 30 minutes to keep the body active.

LOS ANGELES, CA (Merxwire) - How many hours have you spent sitting today? Do you start your day at the office seated at a computer, scroll through your phone during lunch, and then head home only to sit on the couch and binge shows? Studies reveal that, on average, modern adults sit for over 9 hours daily. You might not realise that this "too much sitting" habit is quietly stealing your health and your life.

According to recent studies by the U.S. National Institutes of Health (NIH) and the American Heart Association, individuals who sit for more than 10 hours per day face a 40% increased risk of death from heart failure and a 54% increase in all-cause mortality. The data, drawn from long-term tracking of over 150,000 people, confirm a direct link between sedentary behaviour and serious health issues-particularly cardiovascular disease, diabetes, and even certain cancers.

You might say, "But I exercise regularly! I even go to the gym on weekends!" However, experts caution that exercising three to five times per week does not neutralise the "slow poison" of prolonged sitting. According to a report from the American Cancer Society, exercise cannot completely offset the strain that prolonged sedentary behaviour places on the metabolic and circulatory systems.

So, what exactly does prolonged sitting do to the body? Remaining still for extended periods results in minimal muscle contraction, slower blood circulation, and decreased metabolic efficiency. This can lead to elevated blood sugar and cholesterol levels, eventually contributing to obesity, diabetes, and cognitive decline. For older adults, a sedentary lifestyle also accelerates muscle loss and bone density reduction, increasing the risk of falls and physical disability. Researchers' basic recommendation is simple: for every 30 minutes of sitting, stand and move around for 1 to 2 minutes. Every bit counts, whether getting a glass of water, stretching, or taking a few steps. You can set a reminder on your phone to prompt movement or use a standing desk to reduce overall sitting time.

In addition to frequent short movements, studies recommend incorporating at least 150 minutes of moderate-intensity weekly exercise, such as brisk walking, stair climbing, or cycling, to maintain bodily function. Replacing just one hour of sitting with 12 minutes of light activity (like walking, tidying up, or gardening) can significantly reduce the risk of premature death.

The health impact of prolonged sitting should not be underestimated. If you are an office worker, student, driver, or freelancer-anyone who sits for long periods-take this warning seriously. Regularly standing up, adjusting your working posture, and increasing daily physical activity, you can find practical ways to care for your body amid your busy routine.
