A new study found that being sedentary for over 8.5 hours daily or 60 hours a week while commuting, in the office or at home can make you age faster and raise significant health risks. The study was published in the journal PLOS One.

The study showed that a young age or 20 minutes of moderate activity like walking cannot buffer the effects. Instead, vigorous activity like running or cycling for 30 minutes daily can help, but not completely. Chandra Reynolds, Professor in the Department of Psychology and Neuroscience at the University of Colorado Boulder in the US, and lead author said that “sitting less throughout the day, getting more vigorous exercise, or a combination of both may be necessary to reduce the risk of premature ageing in early adulthood”.

“Taking a quick walk after work may not be enough,” said Reynolds, noting that the “associations are already emerging in early adulthood.” For the study, the team analysed more than 1,000 people with an average age of 33 and included 730 twins to explore how prolonged sitting impacts cholesterol and body mass index (BMI) in young adults. The data was from an ongoing study of over a thousand former or current Coloradans, 730 of who are twins.

Reynolds’ team focused on participants aged 28 to 49. The participants logged 9 hours of sitting daily while engaging in moderate physical activity between 80 and 160 minutes. The results noted that “the more one sat, the older one looked”.

Further, the team said that yo.
