Nowadays, the daily routine of most people involves spending a significant amount of time—from morning until evening—sitting in a chair. Working at a computer for long hours in the office, relaxing on a sofa to watch television after returning home, and using a mobile phone during spare time—these habits are gradually reducing physical activity. While the impact may not be immediately noticeable, the habit of prolonged sitting can be detrimental to one's health. It is linked to weight gain, a slower metabolism, and an increased risk of developing Type 2 diabetes.
What effect does prolonged sitting have on the body?
According to a report by the American Diabetes Association, when we remain seated for several consecutive hours, muscle activity in the body decreases. This can impair the body's ability to utilize glucose and reduce the sensitivity of cells to insulin. Insulin is a hormone that facilitates the transport of sugar from the bloodstream into the body's cells. When the body cannot utilize insulin effectively, blood sugar levels begin to rise. Over time, this can increase the risk of Type 2 diabetes. Furthermore, continuous sitting results in lower calorie expenditure. If this is combined with an unbalanced diet, it can lead to weight gain and the accumulation of fat around the abdomen—both of which can negatively impact metabolic health.
How much movement is necessary?
If your job requires you to sit in a chair for hours, taking a short break every 30 minutes can be beneficial. The American Diabetes Association’s 2026 guidelines recommend standing up, walking around, or engaging in light physical activity at least every 30 minutes during long periods of sitting. Simple ways to incorporate this include taking a 2–5 minute walk, moving around the office, or even standing while working for a short duration. In addition to this, it is important to pay attention to your total daily physical activity. Adults should aim for at least 150 minutes of moderate-intensity exercise per week. For instance, brisk walking for about 30 minutes, five days a week, is a good option. If it is difficult to set aside 30 minutes at once, you can break it up into shorter sessions throughout the morning, afternoon, and evening.
How can you increase your activity level while at the office?
You can keep your body active by adopting a few simple habits during the workday:
– Get up from your seat every half hour and walk around a bit.
– Walk while talking on the phone instead of remaining seated.
– Use the stairs instead of the elevator, provided it is safe for you to do so.
– Take a light 10–15 minute walk after lunch.
– Get up from your desk to get a drink of water, and incorporate some stretching throughout the day.
