Square eyes the least of your problems
EVERY hour you spend sitting watching TV makes you more likely to die from inflammatory-related diseases, Melbourne researchers have found.
Baker Heart and Diabetes Institute researchers have found that even moderate viewing of between two and four hours a day is risky, with every extra hour of seated TV viewing each day associated with a 12 per cent higher risk of inflammation-related death.
Researchers analysed the lifestyles, hours of daily television viewing, inflammatory markers, and causes of death of almost 9000 adults, who were followed up 13 years after first taking part in the Australian diabetes, obesity and lifestyle study.
After excluding cancer and cardiovascular-related deaths, they found that every extra hour of TV time increased the risk of inflammatory-related death. The risk was similar, but smaller, among nonsmokers in the cohort.
“We know sitting involves reduced muscle activity, and therefore reduced blood flow,” lead author and senior researcher at Baker’s physical activity research unit, Dr Megan Grace said. “We think this stagnation in the blood vessels may be leading to an accumulation of inflammatory markers in the blood and muscles.”
