We tend to focus on how many minutes a day we exercise rather than how many hours per day we spend sitting. It is time to pay attention to both! According to two new studies, sitting too much can be detrimental to health.
In one study, less-than-healthy measures of HDL cholesterol, insulin, insulin resistance, triglycerides, and C-reactive protein (a marker linked to heart disease) tend to be associated with sedentary lifestyle. The more time spent sitting, the poorer the lab results. In addition, as sit time increases, the greater waist circumference measurements tend to be. If you have a job that requires you to sit for long periods of time, get up occasionally and walk. Researchers found that getting up and moving around for as little as a minute was linked to improvements in C-reactive protein and also in waist circumference.
In another study, people who spent at least 4 hours a day sitting were more than twice as likely to suffer a cardiovascular event and 52% more likely to die than those with less than 2 hours of sit time.
