THIS is bad news bingers.

Ev­ery hour you spend sit­ting watch­ing TV makes you more likely to die from in­flam­ma­tory-re­lated dis­eases, Mel­bourne re­searchers have found.

And it’s not just those watch­ing more than four hour­long episodes in a row at risk.

Baker Heart and Di­a­betes In­sti­tute re­searchers have found that even mod­er­ate view­ing of be­tween two and four hours daily was risky, with very ex­tra hour of seated TV view­ing per day as­so­ci­ated with a 12 per cent higher risk of in­flam­ma­tion-re­lated death.

Re­searchers an­a­lysed the life­styles, hours of daily TV view­ing, in­flam­ma­tory mark­ers, and causes of death of al­most 9000 adults, who were fol­lowed up 13 years af­ter first for TV 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, in non smok­ers among the co­hort.

Lead author and se­nior re­searcher at Baker’s phys­i­cal ac­tiv­ity re­search unit, Dr Me­gan Grace, said there was grow­ing ev­i­dence that be­ing seden­tary was linked to in­flam­ma­tion.

“We know sit­ting in­volves re­duced mus­cle ac­tiv­ity, and there­fore re­duced blood flow. We think this stag­na­tion in the blood ves­sels may be lead­ing to an ac­cu­mu­la­tion of in­flam­ma­tory mark­ers in the blood and mus­cles,” Dr Grace said.
