Moving a Little is not enough to Offset Sitting….A lot
You exercise in the morning by taking a 20 minute brisk walk with your dog. Maybe you bike for 15 or 20 minutes to work in the morning and evening. Or maybe you go out for a quick 15 minute walk at lunchtime. But the rest of your day is spent sitting in a chair, and once you come home you sit to eat dinner and then watch a few hours of TV……while sitting. Bravo for the commitment to light exercise most days of the week, BUT, according to a new study, its benefits are countered by the many hours of sedentary behavior you engage in daily.
The journal article was a review of many studies that focused on adults between the ages of 18 and 60 years of age, and their physical activity patterns and sedentary behavior patterns. The most common sedentary behaviors were sitting at work, watching TV, computer screen time. Researchers also found that the more hours of sedentary behavior the person engaged in daily, the less time overall the person devoted to “movement” of any kind.
If you sit for most of the day at work, make it a habit to set your phone for hourly alarms that alert you to get up and move around. Take a morning and afternoon “climb stairs break” in your building. Sneak in a lunchtime brisk walk and exercise in front of the TV at night, during commercials. Those are all easy ways to offset the negative health impact of many sitting hours.
