The Telegraph: Every hour of TV watching shortens life by 22 minutes

Via The Telegraph:

Anyone who spends six hours a day in front of the box is at risk of dying five years sooner than those who enjoy more active pastimes, it is claimed.

Researchers say that watching too much TV is as dangerous as smoking or being overweight, and that the “ubiquitous sedentary behaviour” should be seen as a “public health problem”.

Experts from the University of Queensland, Australia, write: “TV viewing time may have adverse health consequences that rival those of lack of physical activity, obesity and smoking; every single hour of TV viewed may shorten life by as much as 22 minutes.”

Referring to Australian and American guidelines that suggest children should spend no more than two hours a day in front of a screen, the academics conclude: “With further corroborative evidence, a public health case could be made that adults also need to limit the time spent watching TV.”

Although health campaigners – and parents – have long warned of the dangers of watching too much television, its effects on life expectancy have never before been calculated.
