We all know that maintaining an active lifestyle is an important part of staying healthy. However, many of us can be “chained” to a desk all day and although we may get in our 30 minutes of moderate physical activity each day, we might not realize that sitting for long periods of time affects our health. In fact, research shows that prolonged television/computer viewing time, particularly more than four hours a day, was associated with higher blood sugar levels, higher blood fat levels, larger waist circumference, and higher risk of metabolic syndrome.
Furthermore, this strong relationship between metabolic health and television/computer viewing time remained significant regardless of how much moderate to vigorous physical activity people did. In other words, even if you’re getting enough moderate physical activity in each day, you may still be at risk of developing these conditions.
Fortunately, the research also showed that people who interrupted their sedentary time more frequently (e.g., got up to get a drink, stood up to answer the phone) were better off in their metabolic health compared to those whose sitting time was mostly uninterrupted.
