According to a recent research, taking small yet frequent walks can help reduce the harm caused by sitting for long hours at work. Sitting all day long in the pursuit of one’s target at work increases the risk of a heart disease, in addition to contributing to other health problems. According to a research study conducted at Indiana University, sitting for a prolonged period of time can cause blood to pool in the legs. This happens because the muscles are not contracting and pumping blood to the heart as effectively. As a result, the ability of blood vessels to expand from increased blood flow can become impaired. Being sedentary is also linked to high cholesterol and a larger waistline, which increase the risk for heart and metabolic disease.
The researchers examined the effects of three hours of sitting on 11 healthy men and found that the ability of the arteries in the legs to expand was reduced by as much as 50 percent after just one hour of sitting. However, the men who walked for five minutes for each hour they spent sitting had no reduction in the function of their arteries during the three-hour period.
The researchers concluded that the increased muscle activity and blood flow from the small amount of exercise offset the negative impacts of sitting.
