A public service word of caution to all those (like myself) looking forward to watching some college football on TV this weekend.
It can kill you.
No joke. But so can a binge session of “Justified”, “Top Gear”, “House of Cards”, “Andy Griffith”, or, as I have been painfully exposed to against my will, “America’s Next Top Model.”
Why, even the DVD series of “The Barbara Mandrell Show” or “The Carol Burnett Show” could be a person’s last memory on this earth. Imagine Carol Burnett’s singing being the last thing a person hears prior to departing this life. That’s not a stretch, actually.
According to research presented at European Society of Cardiology Congress this past Saturday by Mr Toru Shirakawa, public health research fellow in the Department of Social Medicine at Osaka University in Japan, prolonged television watchers are at a much higher risk of fatal pulmonary embolism.
Pulmonary embolism is a blood clot that usually forms in the the legs and travels to the lung. It can cause extreme chest pain, shortness of breath, and sudden death even in an otherwise healthy individual. Many people recognize airline travel as a risk of a pulmonary embolism.
Now watching television is, also.
The research is quite impressive. Over 86,000 people aged 40 to 79 were followed for over 18 years in Japan. Television watching was journaled and the cause of death was confirmed from death certificates.
People were divided into three groups: those who watched 2.5 hours or less per day, those who watch between 2.5 and 4.9 hours per day, and those who watched over 5 hours per day.
(For the number crunchers reading this, yes, the data was adjusted for age at baseline, gender, history of hypertension, history of diabetes, smoking status, drinking status, body mass index, walking and sports habits and menopausal status.)
During the follow up period it was found that 58 people had died from pulmonary embolism. If you think that isn’t many, imagine standing in Neyland Stadium with nearly 100,000 of your nearest kinfolk and friends and nearly 60 people will randomly selected from the crowd. It becomes a very real number.
The researchers determined that people who watched over 5 hours of television per day were twice as likely to have a fatal pulmonary embolism as those who watched 2.5 hours or less.
Even more interesting was the finding that individuals under the age of 60 who watched for over 5 hours had a six-fold greater risk of fatal pulmonary embolism than those who watched less than 2.5. The risk was three-fold greater for the 2.5-4.9 hours of watching in the same group.
This means, a person who is between the ages of 40 and 60 has the greatest risk of fatal pulmonary embolism after watching television for over 5 hours. That is roughly two football games, or one baseball game, or one half of a European soccer game (or so it seems).
That is also equivalent to ten episodes of “The Andy Griffith Show” (easy), two chick flick movies (tougher), or about eight episodes of “America’s Next Top Model” (death already being pondered at that point).
Mr. Shirakawa commented on the findings of his research that leg mobility, much like with flying, needs to be a point of focus during television watching. He suggested that getting up, walking, stretching and drinking plenty of water for hydration during regular breaks from viewing needs to be an emphasis for any age group.
He further noted that fatal pulmonary embolisms have been documented in individuals playing video games, but that it isn’t clear if prolonged usage of computers or smartphones is a risk.
It makes sense, actually, that television viewing would be a risk. The blood in the legs moves back to the heart by the action of the muscles in the legs compressing the veins and pushing the blood up the veins to the heart. The one-way valves in the veins keep the blood from flowing backwards and promotes circulation.
This is the reason that it is important for the legs to move some while we sleep, but of course not enough to keep a spouse awake. It is also the reason there is such an emphasis on hospital admissions to reduce the risk of clots in the legs either by walking, compression devices on the legs, and/or blood thinners.
We weren’t made to be still. We should be still some for rest, prayer, meditation and social courtesy, but not for prolonged periods of time.
We are made to move. Sitting in front of the television (or video game) locks our attention and lowers our motivation to move and be active. It is a habit that can easily be changed.
It isn’t too much of a stretch to imagine the day when the television will have a sensor and a camera looking back at us to determine if we are moving enough. The television will see us sitting still, communicate with our health insurance’s computer, and Boom(!) - change the channel to a re-run of Lawrence Welk and the Polyester Singers. That will get anyone out of the room.
