Every hour spent watching television shortens the viewer’s life by 22 minutes, academics
warn.
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 muchtelevision, its effects on life expectancy have never before been calculated.
In a paper published in the British Journal of Sports Medicine, Dr J Lennert Veerman and colleagues
looked at the results of a survey of 11,247 Australians taken in 1999-2000, which asked about time
spent watching TV, and also mortality figures for the country.
They constructed a model in which they compared life expectancy for adults who watch TV to those
who did not, and worked out that every hour spent glued to the screen shortened life by 21.8 minutes.
For those in the top 1 per cent of the population who watch six hours of programmes a day, they “can
expect to live 4.8 years less than a person who does not watch TV”.
The researchers say that watching TV is among the most common forms of sedentary behaviour, along
with sitting in cars.
“Because TV viewing is a ubiquitous behaviour that occupies significant portions of adults’ leisure
time, its effects are significant for overall population health.”
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these
studies back what we already know - that doing a little bit of physical activity each day brings health
benefits and a sedentary lifestyle carries additional risks.
"That's why the UK's Chief Medical Officers recently updated their advice on physical activity to be
more flexible, right from babyhood to adult life.
"Adults, for example, can get their 150 minutes of activity a week in sessions of 10 minutes or more
and for the first time we have provided guidelines on reducing sedentary time.
"We hope these studies will help more people realise that there are many ways to get exercise -
activities like walking at a good pace or digging the garden over can count too."
Maureen Talbot, senior cardiac nurse at the British Heart Foundation, said: “Sedentary behaviour such
as vegging in front of the TV is practically a cultural institution these days and it’s good to relax for a
while, but this study supports the view that too much of it can be bad for our health.
“Many of us make a conscious decision not to smoke because we know it’s bad for us, and this study
suggests that more of us should make the same kind of pledge about lounging around and watching
lots of TV.“Introducing more activity to our daily lives, whether it’s walking to the shops instead of taking the
bus, using the stairs instead of the lift or taking up active hobbies like sport or gardening mean we
won’t spend as much time in front of the TV where we’re likely to pile on the pounds."
