Asthma Risk Linked To Early TV Viewing 266

Posted by kdawson
from the near-the-carpet dept.
Ponca City, We love you writes "The number of children with asthma has been rising for many years. About 1 in 10 children in the UK develop asthma, compared with about 1 in 25 in the 1960s. The reason for this isn't clear, although several theories have been put forward such as keeping our homes cleaner, and having central heating and more soft furnishings where house dust mites can multiply. Now based on more than 3,000 children whose respiratory health was tracked from birth to 11.5 years of age, researchers have found a new correlation with young children who spend more than two hours glued to the TV every day doubling their subsequent risk of developing asthma. 'This study has shown for the first time a positive association between increased duration of reported TV viewing in early childhood and the development of asthma by 11.5 years of age in children with no symptoms of asthma in early childhood,' said the researchers, led by A. Sherriff, from the University of Glasgow. It's not clear exactly how sedentary behaviors like television watching are tied to asthma, but there is some evidence to suggest exercise and deep breaths that come with it stretch the smooth muscles in the airways, while lack of exercise may make the lungs overly sensitive. The results add asthma to a catalog of undesirable outcomes, including obesity, diabetes, smoking, and promiscuity, tied to TV viewing."

      beat me to the point...

      "promiscuity" being "undesirable" seems in line with the absurd overly-judgmental attitudes toward sex promoted by the far right and the religious zealots

      IMO people would be a *lot* better off being taught healthy norms about sex and encouraged to have more healthy sex - instead of the story that it is somehow bad and needs to be restricted, hidden and controlled by shaming people

The hippies had in mind something that they wanted, and were calling it "freedom," but in the final analysis "freedom" is a purely negative goal. It just says something is bad.

          Hedonism... I think the word does not mean what you think it means.

          Promiscuity, as far as I understand it, just means that you change partners. It does not say how often and it does not say in what situations. It therefore also does not say anything about the value of these relationships.
          Hedonism is supposed to be a world-view that puts the consumption at the top of one's priorities. It is supposed to be selfish.

          That you equate the two shows that you either do not understand their meanings or have, in my op

          • In the course of my life I've changed "partners" several times. I had a partner in elementary school who I called my "best friend", I had another in middle/high school, another in college, another in grad school, and yet another in my workplace.

            I suppose that makes me promiscuous, but I don't care. Each one of my best friends/partners gave me fulfillment at each stage of my life. I don't see anything wrong with that.

          • But it is hard to deny that most people DO enter purely sexual relationships with selfish intentions. It feels good and they want to do it. I'm not saying either extreme (very conservative or promiscuous) is right, just pointing out that the types of relationships you and the parent poster were referring to may be quite different.

          Actually, promiscuity is simple hedonism

          Promiscuity != Hedonism

          Promiscuity is a "large" number of sexual partners. Large being purely subjective in this case. Just because someone is labeled as promiscuous does not mean that they're sleeping with a different person every night, nor does it mean that there's no value attached to the sex that they have. People in long-term, loving multiple-partner relationships are often labeled as promiscuous.

          Hedonism is seeking pleasure above all else, that feeling good is your highest calling. This doesn't necessarily mean sex - it can also mean drugs, alcohol, food, whatever. And, yes, pursuing your own happiness/pleasure at the expense of all else does lead to many ills - social and otherwise.

          The loss of shame leads to many, many social ills.

          Personally, I've found that shame is rarely useful.

          Shame comes in two flavors - your own, and everyone else's.

          Your own shame is typically a result of realizing you did something you probably shouldn't have. I find it is typically better to think things through the first time and avoid the shame alltogether. When I'm trying to make a decision "I might be ashamed" doesn't enter into it - "is it a good decision" does. And typically, if it's a good decision, there's no call for shame.

          Everyone else's shame is an attempt to get you to conform to what they think you should be doing. "You ought to be ashamed!" is someone telling you that you did something they don't like. Unless it's someone you genuinely value - your spouse or parent, for example - those are empty words. I personally couldn't care less whether some random person thinks I should be ashamed or not.

          The "if it feels good, do it" philosophy is bunk.

          If it feels good, why wouldn't you do it?

          Certainly doing it, whatever it may be, to excess is probably going to be bad. But in moderation, as a responsible human being, why not? Why not have sex? Why not eat cake? Why not drink beer? Why not go skiing? Why not read a book? Is there something inherently noble in depriving yourself of pleasure? Is there something wrong with enjoying yourself?

          Degeneracy can be fun but it's hard to keep up as a serious lifetime occupation.

          Most of the time "degeneracy" is a subjective label. If you agree with what someone is doing, to the extent that they're doing it, they're OK. If you don't agree with it, or if they're doing it too much, they're degenerate. And what exactly we label as "degenerate" is strongly influenced by our own morals and values - not any objective analysis.

          If someone likes to read books, are they degenerate? What if they go through a book every single night? What if they avoid social contact in favor of reading? What if they get so hooked on reading that it starts affecting their work? What if they just can't put down a book during lunch and never get that TPS report done? Are they degenerate? Somehow that word just doesn't seem to fit, does it? Addicted maybe... They've certainly got issues... But degenerate?

          Now what if they really like having sex? What if they have sex with someone different every night? What if they spend all their time trying to hook up with a new partner? What if their sexual encounters start affecting their work? What if they get caught fooling around with someone during lunch? I'm guessing the world "degenerate" seems a lot more fitting in this case.

          Most of the western world (not just the US) has been conditioned by immersion in Judeo-Christian values to view sex as somehow separate from normal life activities. It's something secret, sacred, or dirty that polite people don't really talk about. It's something that should only happen between married couples... Or something that should only happen with a certain frequency... Or something that shouldn't involve people of the same gender, or power tools, or animals, or chains, or whatever... Sex has values and judgments attached to it that eating, for example, doesn't. Yet both of those are completely natural, and often pleasurable, parts of human existence.

          If you're feeling empty and lonely, you're not a very good hedonist. There's nothing wrong with being a hedonist, pleasure is good, pain is bad. You just have to be sure your strategy is to maximize total lifetime pleasure, instead of trading future pleasure for immediate pleasure. A real hedonist who values pleasure above all else would realize that the greatest pleasure comes from making others happy.

      I have a theory.

      Scientists say that there is a correlation between growing up in a relatively dust-free environment and developing asthma. Kids who are playing outside are exposed to dust and don't become hypersensitive to it, whereas kids who spend much time in front of the TV are rarely exposed to outside dust, and so they develop asthma.

      everything about this study just screams "correlation is not causation".

      I think what scream loudest in this case is that you are uncomfortable with the implications; perhaps there are things in your lifestyle you don't want to change?

      Taken in isolation this kind of study does seem a little bizarre, and the way it is presented in the popular media doesn't help either, when it is reported as if it was a kind of joke. However, it is part of a growing trend that seems to indicate that a lot of illnesses are actually lifestyle diseases, and there is growing evidence that one common factor is inflammation - or the presence of certain indicators of inflammation, I should say. Inflammation seems to lie behind such things as atherosclerosis, insulin resistence, and of course it is known to a major symptom in asthma. The adipose tissues of obese people seem to be the seat of low-level inflammation too, or something very similar. Now, I don't know about you, but when I see all these things together, I don't think it is all that unlikely that sitting in front of the telly instead of getting up and about actually is a major causative factor in these lifestyle diseases, asthma included.

      It is also well-known that exercise actually is a very effective way of lowering the levels of inflammation in places where you don't want it - perhaps because exercise actually causes low-level damage to muscles and connective tissue; this sort of draws the attention of the body's repair system away from the places where it is not actually supposed to be. Inflammation is an important part of the repair system, which is why muscles get sore from exercise.

      Lazy parents who use the TV as a baby sitter for hours on end are also likely to be lazy when it comes to preparing healthy meals and resort to take away meals and junk food snacks. Also children that suffer from asthma are likely to prefer less arduous activities, like watching TV, in order to reduce the risk of an attack.

      As for the growth in asthma, increasing levels of exotic pollutants (that generate hormonal reactions in people) plus the effects of junk food consumption during pregnancy are the most likely the culprits.

      Feeding neuro stimulant so called 'flavour enhancers' to unborn children is most likely not the brightest idea in the world and maybe the future health of an unborn generation should be put ahead of the profits of junk food and chemical additive manufacturers.

I also belive that obesity causes diabetes and smoking around children increases the risk of asthma, so if there is a correlation between obesity and TV watching and smoking and TV watching then the others probably follow.

As to the whyness of this correlation, meh, we don't really know, nor did we bother to establish a few hypothesises like "oh maybe it's due to socio-economic conditions i.e. poor people watch more TV and live in houses with asbestos hey let's try and find out", nah, we just care about writing a paper and making it buzz for all it's worth cause it's gonna look good on our CVs and you know it's going to work because people love senseless sensationalist drivel like "new research shows that learning to play the violin will make you live 6 years longer!" or "can eating pineapple make you gain IQ points?"."
