Help Your Heart Taking Short Breaks
People who sit for extended periods of time with out taking short breaks are at risk for heart diseases than those who take who take more frequent timeouts to stand up and walk around, suggests a study.The cardiovascular risk that stems from remaining sedimentary for prolonged periods of time(at the office for example) manifests itself in the form of large waists, higher blood pressure, increased body inflammation and low level of 'good' cholesterol. In developed countries people spend more than half of their day sitting on an average. To explore the potential connection between short breaks and cardiovascular risks, researchers from UK followed 4757 men and women aged 20 years and above for 3 years. All the participants had been outfitted with an accelerometer on their hips, to monitor a week's worth of walking,running and sitting routine. Researchers also looked at heart disease-related risks factors, including blood pressure and cholesterol level. The most sedentary participants were found to sit a little more than 2 hours per day. It was found that longer the participants spent being sedentary the longer was their waste circumference. Overall, those who who took the most breaks from sitting were found to have small waists. The finding suggest that even small changes to person's activity levels might help to lower cardiovascular risks. These changes can be readily incorporated into one's day to day including the work environment.
