Is Air Conditioning Making You Sick?

Is Air Conditioning Making You Sick?


Cool air in the hot summer is the best…
but does it make me sicker? Hey everyone thanks for watching DNews today,
I’m Trace. American inventor Willis Carrier invented
the first AC unit in 1902, and it was first put into a theater in 1925 and homes by 1965
after it had spread through commercial and retail spaces. Ancient Roman philosopher Seneca
disparaged the “skinny youths” who ate snow to keep cool rather than bearing the heat
like a real Roman. Basically what I’m trying to is that cooling has been around now but
it Cooling has been contentious forever, and it’s not getting better. People have long felt the pull of “fresh air”
over “indoor air,” and there are some studies that support that idea. The World Health Organization
uses the term “sick building syndrome” (SBS) for people who breathe the air in a specific
building and experience similar acute health effects. A 2004 French study found of 920
women, those who worked in air conditioned buildings were twice as likely to take a sick
day, or visit an ear-nose-throat doctor. Plus, studies have shown cold air weakens the immune
system against viruses in mice, showing cold air MIGHT affect humans too. The thing is,
as AC units cool the air, they also filter it! Fresh air ain’t filtered, it’s au naturale. So though the AC might be cooling the air,
it’s making it better.. maybe? A good air conditioning unit is built around
a system of coils containing chemical refrigerants which absorb heat from the air. The refrigerant
can vary, but it’s usually some configuration of chlorofluorocarbon. The coils are a closed
system of that liquid refrigerant. When the unit is on, the coils absorb heat from the
outdoor air, passing it to the chlorofluorocarbon which becomes a gas. That chlorofluorocarbon
gas is compressed into smaller coils, forcing it to release the absorbed heat and return
to a liquid state. It does this over and over and over again. That heat is blown outside
and the cool air blown inside through a HEPA filter to clean the air a bit! While none of that sounds particularly evil
and doesn’t seem like it would make you sick, for some reason people are still wary
of “indoor air.” In fact, someone once said, “No pleasure, no rapture, no exquisite sin
greater… than central air.” But there’s no direct link between air conditioning and
SBS or any sickness at all, just a correlation. Scientists at the University of Cardiff say,
what’s more likely is AC units dry the air as they cool, which might dry mucous membranes
in the ears, nose or throat, allowing viruses to gain a foothold… that explains the women
who were going to the doctor twice as often. Of course, sickness aside, there are QUANTIFIABLE
problems with air conditioning, AC consumes 5 percent of all US electricity during the
summer; that’s two tons of CO2 per house per year! As the world gets richer, more and more
AC units are sold, requiring more power, and polluting even more. In the US around 90 percent
of households have AC, but in Africa, South Asia, and Central America AC is still rare.
Though in china 64 million AC units were sold in China in 2013 alone! Growing up in Michigan, where the highs can
reach mid-80s with high humidity in the summer; we didn’t even have AC until I was in Middle
School. But I have to say, What’s up with restaurants making it 55 inside when it’s
85 outside? That’s the worst! Air conditioning is great, but c’mon. And yes, I realize this
is a First world problem, fer sure. But this is part of the energy usage issue. The US
Department of Energy says your energy bill increases 1-3 percent for every 1 degree fahrenheit
change (0.56 C), which means for every degree we’re putting MORE greenhouse gas out. Plus,
the warmer your house, the less heat you lose to the surrounding environment, and the less
your AC unit has to work in the summer. 65 degrees (18C) is the optimal temperature for
sleeping, to keep your home appliances humming, and anything below 70 helps you lose weight
naturally!

    65 degrees???? That's too cold. In the winter, I like to heat my apartment up to about 76 and leave it off the rest of the day. If you are insulated well enough, you shouldn't lose your heat to the outside. And vise versa, in the summer I cool the apartment and turn it off the majority of the day. Usually, I leave it off during the night too and always when I leave the apartment. I pay around $30-$35 in utilities.

    Did anybody else have that dream where the government would build a huge skyscraper (which is actually an AC) that cools down the entire earth so we don't have to sweat anymore. Am I the only one?

    I live in Rio, in summer is literally impossible to sleep without air conditioning. Those sick 35ºC nights. Now it's winter so around 3~4 AM we sometimes have 18ºC. I can't remember the last time I felt the need of using a sweater. Long history short: air conditioning the whole year.

    I was immune to ac when i lived in malaysia, putting it at 16 degrees all day long. Came to Canada and lived here for 5 years. Went back to Malaysia, and caught a cold every time I turned the ac on.

    18°C?! I would freeze my balls at that temp! My ac doesn't even go below 16°C. I found that the optimal temperature is around 24°C.

    Energi consumption does not have to increase. Despite a significant increase in produktivity and a population growth of 10 % since 1970. The country uses less energy now than 45 years ago.

    I live in Denmark, people here rarely have AC partly because we regard it as wastefull, and off course partly because it rarely gets hotter than 30C here ind the summer. i can't think of anyone i know that have AC in their house.

    AC is my life and i've been using it for the last 10 years, i usually sleep with it turned on, otherwise i wake up in the middle of the nights sweating……apart from chicken pox, i have never been sick, never taken medicine, so health issues are unknown to me, i just clean the filter every year and thats about it. I never go to places that don't have AC's, if restaurants aren't cold i can't stay there, anithing above 22 degrees celcius is hot to me, and i begin to sweat. So long live AC, i will make a statue for Willis 😀

    I was in America once, and it was so annoying to always take my jacket with me, not because it was cold outside, no, because it was cold in the restaurants!! that's horrible, who came on that idea?

    yup, hate super chilly temperatures indoors when it's hot outside.
    Not only because my nose and throat get stuffy but my muscles hurt from the sudden change in temperature… so I have to carry around tissue for my nose but advil for my muscle pain.

    on a side note, how does a swamp cooler work? I've been told it's better than an a/c for the environment, but that it's too big to be popular right now. I was at a store last night and saw a portable one… I wonder if it's worth buying. If it works differently than an a/c maybe my nose wont get stuffy.

    I have a skin disease called epidermolysis bullosa simplex. I basically can't survive without air conditioning because too much heat basically causes my skin to boil. Sadly, it means I'm unable to save energy on air conditioning. But I do try to make up for it by being more conscious in other areas.

    Great fed as usual but you showed me an awesome video clip about spicy food, making me want to see it, but I'm on my phone and sadly you didn't post a link to it in the description so I had to search for it. No this is me coming back from that vid and may I say that it was just as good as expected, but please… PLEASE start putting links in the description for videos that you show the clip of at the end of your current video.

    You guys are awesome though 🙂

    I live on the attic here… altho I don't have a real AC, I build something myself that while not able to cool the whole room, gives me a nice temperature in the corner where I sit… it takes about the same amount of power as my laptop does, so it's not that much…

    Most homes in Canada don't even have AC (at least not Western Canada). It's only hot enough for a few weeks out of the entire year to warrant them. Although it's still super common in commercial buildings, and not uncommon in condos.

    I don't like the noise of AC units.  Particularly badly maintained or operated ones. I only run mine when its really hot, so I am often listening to the rumble of other less nature connected neighbors.

    That still doesn't answer the question, "Does moving from a cold room with AC out into the hot air significantly increase my chances of getting sick?" That's what I came here to find out 🙁 Trace is cool tho 🙂

    I absolutely hate air conditioning. Why do people wait for warmer weather and then blast the air conditioner to make you shiver? It's like the winter. People blast the furnace so you can cook an egg without a frying pan. Many people I know, have respiratory problems, and they are constantly blasting the air conditioner. No wonder people get summer colds. Air conditioning is overused. I see people complain about their food being cold at restaurants. It doesn't help to be in 55 degree air.

    I don't like AC. I'm staying in a hotel and the first thing I did when I arrived was to turn the AC off and left a note to the housekeeper to leave it that way. The temperature outside is always below 30C so I don't see the need for it.

    Hi  I have worked on AC units for over 30 years. The biggest problem in my opinion is the routine service of a system iewashable filters checked and washed on regular periods .Panel filters replaced again regular . Biggest problem are dirty condensate trays which are wet and breed all sorts of germs. I have worked on office building that was labelled sick building environment this was fan coil system all with dirty slimey condensate trays. All cleaned.

    Well I have a question, Why you need to cool your indoors if the temperature outside is only 29 degree C ? I Live in India, right now, the temperature outside is around 42 degree C, but still now I am not using AC in my room. Well that doesn't mean I hate AC, but affording one and the bills here is still a big problem for a middle class family.
    Can you make a video that the people of Asia and Africa where temperature is really really high, should people living there use AC? I think it may cause a health issue too, because the temperature outside will be the TWICE of the temperature inside. Can sudden change of this temperature make us sick ? Please reply if possible.

    I guess you've never heard of the new inverter technology? these systems run on DC power and preparing little amperage they have up to five stages of cooling loads you might want to look into it they're pretty cool

    dehumidification is a cause… also one factor is that being unable to endure the heat outside.. certainly it will affect harshly for people who have to work mostly outside..

    Air conditioning always makes sick when i use it either at home or in car. I think in my knowledge and for sure does a chemical problems in there. The manufactories they need to make sue to give us a clean natural Air with No Chemical involves. For now I am just using a Fan and i feel bette that way.

    FINALLY!!! Thank u Trace!!! It is a useful vid about AC vs viruses!!! This is so important to get to know if u have an AC u have to make it clean regular!!! And a lot of pp have no idea about that… sadly… Not to mention about temp. differences… I agree with Viktoria6665! When I am not in the office or my house the AC is ON and when I am in the office or house I turn OFF the AC or I am not in the room when it is ON.. This is so easy but I know I am not all the pp XD

    The latest iteration of earthship designs keep your home 70 deg year round (taos, NM climate) no ac, no heat needed. In a basic house swamp coolers can work, I hear. AC starts being really important at about 100F for me. Or if you are suffering from inflammation or for the people recovering I would go for the real deal AC with solar panels and a generator backup to always keep it like 70-80 deg and never go over.

    I don't have central air conditioning in my bedroom. I do have a window unit, but I rarely use it. Instead, I put a fan in an open window and draw air from the outside in. I am rarely sick, but I do have migraines. You can't win them all.

    I keep my room temperature at 25 degree Celsius in hot summer. It's about 45 degree outside. In night, I keep at 21 degree with sleep mode on. In sleep mode it increases 1 degree every two hours. 18 degree is nice but I have to save money as not rich.

    What about the consequences of recirculating the same air over and over again inside a room for prolonged period (not talking about HVAC with AHU Units)
    Doesn't that deplete Oxygen content and increase other gases %? What about long term health impact of this?
    This is especially dangerous if someone smokes inside and the remainder gases keeps circulating indoors…

    In a third-world tropical country where I live, not having AC means you will constantly sweat while inhaling humid air all year round, and opening the windows will just add more pollution in the mixture especially when a neighbour is indifferently burning rubbish (as it is a norm and a non-issue for anyone else).
