Sitting Over 8 Hours Daily Can Raise Health Risks Even After Exercise: Study

A new study reveals that prolonged sitting, defined as being sedentary for more than 8.5 hours daily or over 60 hours weekly, accelerates aging and significantly increases health risks. The study highlights that even young age and moderate exercise, like 20 minutes of walking, cannot offset these effects. Instead, researchers suggest 30 minutes of vigorous exercise, such as running or cycling, as more beneficial, though it may not completely negate the risks.

Chandra Reynolds, Professor at the University of Colorado Boulder, emphasized the importance of staying active, saying, “Sitting less throughout the day, getting more vigorous exercise, or a combination of both may be necessary to reduce the risk of premature aging in early adulthood.”

Higher Risk of Health Issues Observed in Sedentary Young Adults

The study examined over 1,000 participants, including 730 twins, with an average age of 33, to assess the effects of extended sitting on health metrics like cholesterol and body mass index (BMI). On average, participants spent nine hours seated each day, despite engaging in moderate physical activity ranging between 80 and 160 minutes.

Findings published in PLOS One suggest that prolonged sitting can increase visible signs of aging. According to the study, young adults who sit for 8.5 hours daily without vigorous exercise fall into a “moderate to high risk” category for cardiovascular and metabolic diseases.

Vigorous Exercise Helps But Isn’t a Cure-All

The study noted that individuals who engaged in 30 minutes of vigorous daily exercise exhibited healthier cholesterol and BMI levels, comparable to people five to ten years younger. However, Reynolds warned, “Taking a quick walk after work may not be enough,” highlighting that early signs of health risks are already emerging in young adults.

To reduce sitting time, researchers advise incorporating standing desks, taking regular breaks, and organizing walking meetings to lower health risks in both office and home settings.
