Is Conference Room Air Making You Dumber? (nytimes.com) 112

schwit1 shares a report: At least eight studies in the last seven years have looked at what happens specifically in a room accumulating carbon dioxide, a main ingredient in our exhalations. While the results are inconsistent, they are also intriguing. They suggest that while the kinds of air pollution known to cause cancer and asthma remain much more pressing as public health concerns, there may also be pollutants whose most detrimental effects are on the mind, rather than the body.

So can you trust the decisions made in small rooms? How much does the quality of air indoors affect your cognitive abilities? And as our knowledge of indoor air's effects grows, do we need to revise how we design and use our buildings? Buildings in the United States have grown better sealed in the last 50 years, helping reduce energy used in heating and cooling. That's also made it easier for gasses and other substances released by humans and our belongings to build up inside. Although indoor air quality is not as well monitored as the air outdoors, scientists and ventilation professionals have extensively monitored carbon dioxide indoors. Higher CO2 levels -- say, above 1,200 parts per million (ppm) -- often indicate a low ventilation rate. Worrisome substances emitted by new furniture, office supplies and carpets could be accumulating in the air.

    ... but what they *say* in the conference, however, certainly makes you dumber...

    • It is not just the air. Neckties also make them dumber [news-medical.net].

      What would happen if all conference rooms had O2 scrubbers [wikipedia.org]? Or maybe the entire office should be scrubbed. What would be the collective effect on our economy if every enclosed workspace was scrubbed?

        I think you meant a CO2 scrubber. But as I think about some meetings I have been in, an O2 scrubber could have helped a lot. Just turn it on as you leave the room, leaving the managers behind, and problems solved.
      • It is not just the air. Neckties also make them dumber

        That's why wearing neck ties is a requirement for managers, obviously.

        It would be far easier and cheaper to just bring in more outside air.
        Also, if you rely on CO2 scrubbers rather than ventilation, you only take care of CO2, and not other indoor pollutants.

    We can solve this easily [dilbert.com], we just need the will to do so. Also, don't forget how often cube farms get reconfigured with new walls that are outgassing all kinds of wonderful petrochemical effluents. Maybe NASA's research [nasa.gov] on this can provide some potential solutions, too.

      Moss is actually pretty good for your indoor environment. Very easy to keep alive, and provides some decent air scrubbing.

      I use an electronic air cleaner, with HEPA filter and ion generator. I keep one on my desk at work too, and it's entirely anecdotal but I seem to get ill less, particularly common airborne diseases like colds.

      • I understand the appeal of HEPA filtration but why would you want to generate ions to breath in? Otherwise, yes, having plants around is always good for the air unless you've mold allergies.
        • by AmiMoJo ( 196126 )

          They generate positive and negative ions, which kill bacteria and viruses. In other words smells and things that make you ill. They also help stop things like mould growing.

          • As a microbiologist I'm going to have to say that while trapping said microbes in a HEPA filter works very well, I have a hard time beleiving the ion thing is effective as a disinfectant at concentrations that would be safe for humans... even UV sterilization isn't very good. I suppose I'll have to look up the literature some time. I can see how it might help with smells.

              There was a test of them on the TV many years ago. Can't say how well controlled it was, it was on NHK so at least not commercially motivated. Anyway, they got some different models and some sandwiches.

              They put one purifier and one sandwich in a large box with some small holes to allow air to flow, and filmed them over several days. The control sandwich got mouldy pretty quickly as expected, the ones with ion emissions just dried out but didn't start to change colour or stink.

          Because it smells like after a heavy rain or thunderstorm.

    I want fresh air, dammit.

    • I want fresh air, dammit.

      Nearly all modern HVAC systems include fresh air intake [contractingbusiness.com] as an important aspect of their indoor air quality, in addition to heating and cooling the office space.

      • by sjames ( 1099 )

        And since it slightly increases the cooling bill, closing the fresh air intake is the first thing that happens when the building owner needs a new winter yacht.

        • And since it slightly decreases the overall performance of the air conditioner, it is sometimes closed by the repair company's technician at the first service call for "not cooling/heating properly".

    • I want fresh air, dammit.

      There's nothing wrong in general with having windows that can be opened.

      But you also want a high quality internal circulation system, and sometimes you don't want the windows open.

      For several months after a major wildfire near my workplace, I could tell the difference between the air quality at work, and the air quality in my apartment. At work had a typical internal circulation system. In my apartment, I had high quality air cleaners running 24/7. It was an incredible difference.

      I'm pretty sure the time

    I saw an interview with Chris Hadfield (astronaut from Canada, former commander of the International Space Station), and he remarked that, as CO2 levels fluctuate on the space station, the astronauts notice the effects on their bodies and moods.

    The ISS keeps its CO2 levels below 1%, but well above the 0.04% (400 ppm) in Earth's atmosphere, because extracting CO2 from the station's atmosphere is a very energy-intensive process with diminishing returns. This may have the effect of causing astronauts' blood vessels to dilate and fill with fluid, to compensate for increased CO2 levels and keep blood pH down, but also causing increased blood pressure in the brain (also exacerbated by living in microgravity).

      This same exact thing happens to Submariners. In the mid/late 80's, I took some training cruises on US Navy Submarines. The air quality, including the CO2 levels, were shown on a monitoring device that anyone could go by and look at. O2 Levels were always within normal levels but we, the crew, could always tell when the CO2 levels were higher than normal because we felt like crap. That was also the reason why anything with caffeine (coffee/coke) was consumed in large quantities.

  • Could you summarize this in a PowerPoint presentation?

  • Truly the most click baity headline I have seen all year.

  • ... in Dallas was the most "meetingest" goddam place I've ever been.

    One time at band camp ...

    No, it was right before a meeting, the manager called us all together so we could talk about our Power Point slide decks and I said, "Fuck! It's a goddam meeting about the goddam meeting."

    We never got anything done at those meetings.

    • I once heard about a proposal to hold some meetings to decide who should be invited to the planning meetings they needed to draft policy on how to draft compliant policies. We all had a good laugh.
  • So this is any worse?  Makes me long for the days of smoke-filled rooms.
  • CO2 only account for about 4% of what we breathe out. Nitrogen gas remains the main ingredient by a long shot.

    • by Dunbal ( 464142 ) *
      Good thing nitrogen gas is fairly inert unless you start zapping it with electricity.
  • HVAC uses make-up-air fans and exhaust fans to prevent these problems. If the CO2 levels are too high, there is a problem with the building.

    • by havana9 ( 101033 )
      More precisely there is a problem with the HVAC and heating system, especially if coupled with room without windows on the outside and windows that could be opened. In my experience HVAC system are normally problematic because they thend to recirculate the air instead to get an external air intake to save on energy used to heat or cool. I had an office with a linoleum floor like a basket field, and in the morning there was the typical basketball "stink", especially in the winter I always opened the windows
  • It's not the air, it's mind-numbing stupidity of the participants making moronic suggestions and pontificating at length on subjects upon which they know little or nothing about.

    I thought it was just a saying, but it turns out you really can feel your eyes glazing over.

  • I've noticed, when I go to a play or classical music concert, I feel more sleepy. I often doze off during the first act of a three-act play. I've suspected that it was related to elevated CO2 concentrations.

    • by AmiMoJo ( 196126 )

      I sometimes get the same but wonder if it's related to the amount of dust in those places. It quickly builds up and starts making it harder to breath, as in I have to work harder to force air through my partially blocked nostrils. Then I start to feel sleepy until I can clear them.

  • It's a conspiracy coming down from the highest order. To contaminate. Our precious. Bodily. Fluids.
  • Usually it's the idiots demanding we hold conference meetings over the most trivial of shit that's making us dumber.
    No one can f*cking make a decision these days without calling a meeting together and arguing about it for months.

    Hell, it's so bad they call a MEETING to get everyone's input on what the best days and times are to hold meetings :|

    They're inconsistent because they're probably wrong.

    Mountaineers regularly climbing above altitudes where there is less than 45% oxygen. Yes, we also sleep up there too. For Everest base camp, you regularly sleep in small rooms with multiple people.

    Unless you're running around in a tiny box, I can't really see the amount you exhale having much effect on the O2 content. Your diet would probably have a much bigger impact

      Who is talking about O2? We're highly sensitive to CO2 at what amount to trace levels when compared to normal O2 levels.

      Mountaineers regularly climbing above altitudes where there is less than 45% oxygen.

      Unless I'm horribly misinformed, you're not even talking about oxygen levels. You're talking about a decline in the oxygen partial pressure relative to sea level, which directly correlat

  • Just . . . any meetings. Meetings are a waste of time, breath, time, energy, and time.

  • The bottom line is that the subject study is one of at least 8 studies, some that have concluded that low carbon dioxide levels have no effect, some that have concluded CO2 levels have significant effects. Many of the studies are not that great, though, having few subjects or not controlling for other factors. This link [lbl.gov] and this link [nih.gov]within TFA are much better than the summary.
