How many hours do spend in front of the screen?

January 25, 2011 by  

In a previous post, I discussed a study that indicates that 2 hours is the maximum duration of time we should spend in front of a screen during leisure hours. To recap what the study authors have to say:

“This is a new research area, which has attracted attention only in the past 18 months to two years, but it has implications both for public-health recommendations and clinical guidelines. I think there is a direct message from our research, which is that there should be a cut-off of two hours daily screen time as a maximum during leisure hours.”

Unfortunately, I do not fully understand why this 2-hour limit should only apply to leisure hours. What about those who spend the whole day in front of a computer screen? And what about the fact that the boundary between working and leisure hours becomes hazy? A nephew of mine earns his living by playing the X-Box 8 hours a day.

 So how much time do we really spend in front of the screen? There are many numbers and figures around but surprisingly few from reliable sources and up-to-date data. Here are some figures  from

According to many sources, Americans spend 2.6 million minutes on Facebook each day.

The American Heart Association conducted a survey in 2009 and reported the following figures on social network use:

  • 37% of respondents (35% men, 39% women) spend less than an hour social networking
  • 18% spend 1 to 2 hours
  • 7 % spend 2 to 3 hours
  • 3% spend 3 to 4 hours
  • 3% spend more than 4 hours, especially those aged between 18 and 25.

According to figures from the Kaiser Family Foundation (KFF) (as quoted in

Those who smoke together can quit together

Does an extensive social network help in quitting? Apparently yes, accohands togetherrding to a study partially supported by the National Institutes of Health (NIH). Smokers are known to have flocking behavior and this behavior seems to help in quitting as well. In other words, it is easier to quit as a group.

When smoking was still socially acceptable and not considered a health threat, smokers and nonsmokers tended to mix socially a lot. After evidence of the bad effects of passive or secondhand smoking came to light, smokers and nonsmokers tended to form distinct clusters. And with the recently implemented strong anti-smoking laws, smokers have become marginalized. Now more than ever does one need a social network. It makes it easier to deal with the marginalization – and with quitting.

The current study by researchers at Harvard analyzed the social network and behavior of 12,067 people who are part of the Framingham Heart Study (FHS). The FHS is a long-term study that collects comprehensive measures of cardiovascular health and risk factors in a community connected as family, friends and co-workers spanning three generations.

Analysis showed that the closer the relationship to an individual, the greater is the influence on behavioral change including quitting smoking.

Here are some of the interesting findings of the study:

Other interesting aspects of the study showed that geography plays a much lesser role than the closeness of a relationship. Thus, emotional ties help more that physical distance when it comes to quitting.

According to Dr. Richard Suzman, director of the NIA’s Division of Behavioral and Social Research

“This study has an essential public health message—that no one is an island—our health is partially determined by our social networks and those around us. The decision to quit smoking cascaded throughout the web, indicating that some form of collective decision-making was taking place. The results suggest new and probably more powerful approaches to changing health behaviors, such as smoking, by careful targeting of small peer groups as well as single individuals.”

In all types of addiction, a support group has always been important. In quitting to smoke, it doesn’t have to be a formally organized support group. It’s family and friends that count, wherever they are. In today’s technology driven world, keeping in contact is easier than ever. An SMS, a tweet or a Facebook poke can tell us that someone out there cares and is cheering on our efforts. And that is comforting and encouraging.
