Sitting is a big part of modern life. Many people work at a desk all day, have long commutes, or at least enjoy some time relaxing on the couch at the end of the day. But sitting has gained a reputation as being bad for us—with some going so far as to call it “the new smoking”.
A recent study in the journal PLOS One sheds more light on just how much sitting is too much, using a cohort of more than 1,000 young adults, including 730 twins. The results showed that sitting for more than about eight and a half hours per day is linked to a higher total cholesterol and body mass index than sitting for less than that amount of time.
But there’s good news: 30 minutes of vigorous exercise per day may counter the negative effects that come from long days of sitting.
Joining guest host Kathleen Davis to discuss the findings are two of the study authors: Dr. Chandra Reynolds, professor in the Institute of Behavioral Genetics at the University of Colorado, Boulder; and Ryan Bruellman, PhD candidate in genetics, genomics, and bioinformatics at the University of California, Riverside.
