Too much tv could shorten your life, to put the TV look ' in the same ballpark as smoking and obesity», say researchers. Photo: Fancy/Pangs/CorbisTv too much could shorten your life, suggests a study. Research carried out Australiain, and published in the British Journal of Sports Medicine, showed that every hour of tv watched after 25 years may shorten life span by 22 minutes.
According to one of the report's authors, Dr. Lennert Veerman, from the school of public health at the University of Queensland, it enables long hours spent in front of the box "in the same ballpark as smoking and obesity". "While smoking rates are declining, watching TV is not, which have repercussions at a level, population," he said.
Last year, another Australian study took an hour of tv a day led to an 8% increase in the risk of premature death.
"We have taken this survey and translated it into what it means for life expectancy in Australia given how much TV we see," Veerman said.
Australians see approximately two hours of tv a day. As a consequence, their life expectancy at birth reduced by 1.8 years for men and 1,5 years for women, according to the study. Britons see more than three hours of TV a day, according to the broadcasters ' audience Research Board.
Too much sitting, as distinct from too little exercise, are associated with higher mortality risk, especially from cardiovascular disease. "Logically, we know that physical activity is good for health and so it is not surprising that the reverse is not so good," Veerman said.
The report was based on an observational survey conducted in 1999-2000 with more than 11,000 participants aged 25 and over. Participants reported the amount of time they spent watching TV or videos in the previous week, when it was their main activity (ie, do not do the cooking or ironing at the same time).
The report showed also a person who is an average of six hours of TV a day would live an average of 4.8 years less than a person who no-clocks-clocks.
