AIR conditioning has proved to be a boon to those who must live and work in hot and humid climates. It has been a large factor in the development of the âÂÂSun Beltâ of the United States. Without it, not many would choose to live for weeks on end where daily summer temperatures range from 90àto 100àdegrees Fahrenheit, or even hotter.
But, like many blessings of technology, air conditioning is not without its drawbacks. The ease of fingertip control of the temperature has led many to overuse it. âÂÂIf cool is good, cooler is better,â has been their thinking. But medical researchers are now beginning to recognize hazards to health in the immoderate use of air conditioning.
Many persons with various ailments do not need to be told that excessive air conditioning hurts them. People with arthritis find their joints more painful. Those with neuritis have the pain aggravated. A person with sinus trouble comes out with his head congested. One with chronic middle-ear infection risks an acute flare-up of his illness.
In addition to the immediate trauma to those so afflicted, there are more subtle damages to the well-being of the healthy. These are of such a nature that the cause may not even be suspected. But when persons who work in air-conditioned quarters are compared with others, they are found to be more susceptible to all kinds of minor ailments.
Morton Walker says in his book Total Health: âÂÂThermal stress affects the body when it becomes overheated or chilled. An example is sitting in a draft or walking into an air conditioned store from a broiling hot street on a summer day. The body responds, but when forced to do so too often, it shows symptoms of illness.âÂÂ
Studies in New York city showed that people do not get acclimated to summer temperatures the way they did before air conditioning was used. The result is that severe heat waves now take a higher death toll. The trend is to build apartments and office buildings shut off from outside air. This trend risks suffering and death from heat if an extended power shortage occurs.
Experts who are concerned about the long-term effects of air conditioning suggest we ought not to rely entirely on refrigeration for cooling. The designing of buildings to take advantage of natural ventilation, more use of fans only to move the air, and evaporative cooling are some of the alternatives.
For those whose specific ailments are aggravated by air conditioning, the obvious remedy is to avoid it as much as possible. But of those in good health, not many will consider an obscure or future threat to their health a sufficient reason to forgo the immediate comfort of air conditioning. Nevertheless, prudence would tell us to at least be moderate in our dependence on it.
In public buildings you may be at the mercy of custodians who make it their goal to create a polar environment. All you can do is finish your business and get out. But where you work, and in your own home, you can do something about it. Perhaps an enlightening discussion with fellow workers will lead to a consensus to avoid overcooling. And at home, remember that your air conditioner is not to make you cold, just comfortable. Set the thermostat at 78ÃÂ degrees, or higher if you wish. You will find this a healthier climate in which to live.
...not many will consider an obscure or future threat to their health a sufficient reason to forgo the immediate comfort of air conditioning.
True
...you may be at the mercy of custodians who make it their goal to create a polar environment.
That's my goal.
Your post seems irrelevant at a site that supports the repair and use of air conditioning. But, thank you for the warning.

That goes both ways. To me if you set it at 78 you might as well not use it at all. Does this person set it so it is JUST comfortable in the winter too? Or do they set it to 78 then too? people come up with so many phobias about air-conditioning that it isn't funny. Why isn't there phobias about heating your house to 80 degrees when it is below 0 outside?

Major problem with HVAC and even the airliners is limiting the number of air exchanges per hour in a closed confined space where mold, bacteria, and viruses can multiply in the ventilation system. Augmented by jamming a bunch of people in a confined space with them generating excess amounts of CO2 that causes drowsiness.
Fresh air intake in a vehicle really isn't fresh air when fed by the exhaust pipe in the vehicle in front of you.
Picked up a weird virus in my last airline flight, just one person can infect 300 or more people. Its cheaper to reheat or cool existing air than to bring in fresh air occasionally. This is what the problem is, not the temperature.
Hey guys, I have a question. 2005Equinix talked about keeping the temp at 78F. In a humid environment, like here in DFW, wouldn't that keep the humidity down? Lower humidity generally means more comfort - no sticky clothes.
For the record we keep ours at 71 degrees in the summer. What I was saying earlier is that at 78 degrees it isnt going to run enough to make much difference anyway. I would rather be cool than hot since our climate is generally cool anyway. And yes the A/C works in all of my cars. And 78 degrees in an enclosed building for me isnt healthy. Makes me feel claustrophobic. Like i said this is the same guy that would heat his house to 78 degrees in the wintertime here in Wisconsin and think thats ok.

So Boeing is now claiming half the air is fresh. Doing some math, that means the other half is recirculated, but that is on the new stuff. What about the old stuff? Tempted to bring my CO2 and O2 meters with me on the next flight I take, but sure they would be confiscated as those guards wouldn't know what he heck they were for.
When I was making many flights, always was picking up some foreign virus, and got another one just last month from my first flight in a year. Make believe you are getting fresh clean air. Consumers Report had several articles on this subject over the years, normally don't believe half of what hey say, but do believe about contamination in airliners when they jam 300-400 people in a tight sealed can.
And the more fresh air they bring in, the more fuel they will consume, since they are now charging three bucks for a bag with two peanuts in it now, probably will be charging extra for air.
I have close to 2,000,000 air miles and never once did I ever get sick - cold/flu/etc - from flying. And, this includes time back when smoking was allowed in the back of the plane. I think this air/health issue is totally overblown.
One problem with drawing the air in through using the inlet fans of the engines is you very often get engine oil fumes leaking past the oil seals and getting into the cabin air. That's why I've quite often noticed a quite oily smell particularly when they first spin up the engines after initial taxi from the stand.......nearly every time and I don't fly so often

You are absolutely right about the oily smell. While I was flying, occasionally there would be fog in the cabin for a few seconds while the airplane was reaching for altitude. A pilot explained that we had just passed thru a very dense cloud layer and the moisture overwhelmed the air conditioning compressor. I always wondered if that was the real reason.
Use to use shrouds around the exhaust manifold or even the muffler in the 1920's to get heat in the cabin of cars, but quit doing that when people started dying from CO poisoning. But still using that principle in aircraft. With cars today, have to be concerned about even a pinhole leak in a hot water heating system, the anti-freeze can cause kidney damage.
Find it humorous to read any manual regarding the integrity of your own exhaust system for leaks that can lead to death when you have a zillion other exhaust pipes around you. I minimize the use of my own recir door, actually prefer to drive with my window down, but can't do that with kids or women aboard. Can only recall a small handful of times I picked up a bug on an airliner with lots of years of traveling, the last flight is most fresh in my mind.
I guess most people are fairly immune to all the toxins from the oil, because I watched a "Panorama" documentary where they were described as 'fume events' and apparently they're not that rare.
Seems as post is 'much to do about nothing'...perhaps a 'greenie' who wishes us all 'save' the planet. Heard an older George Carlin monologue the concerning the state of 'earth warming'. It was quite enlightening. Miss that guy.
For what is worth....I purchased my home with the most efficient AC possible at the time....currently considering an updated system....but in reference to this post....I purchased this unit to make my home as comfortable and as cold as I wish it to be.
As HECAT stated this post is irrelevant....heck it is totally ridiculous.....think I'll turn my controller down to 70...get it verrrrrrrrrrrry comfortable.....besides FL Power needs the extra cash.
Oh as a side note,have noticed that in many hotels that AC activation is keyed to movement in the room. The sensor detects a lack of movement and shuts the unit down. Set the thermo as low as you wish...but after about an hour,the darn thing shuts down. This can make for some very uncomfortable evenings. The only way I can sleep in a hotel is to turn the AC down as low as possible and 'hibernate' for the evening. That is acceptable....I paid the room rate to allow me that freedom.
Ya'll have fun out there tomorrow!!!

Is you suffer from hay fever or asthma, air conditioning can be a life saver. Also accustomed to listening to news in high polluted cities warning the population to stay indoors. Would think if all your windows and doors were wide open, that wouldn't make any difference. Also reports about people dying in overheated buildings during heat waves without AC.
These are just some counter arguments against the posted article.
Sure like my wife's condo in Venezuela, 25 miles outside of Caracas built on top of a 3,300 foot mountain, air is clean, windows are always open, never gets below 65 or above 75*F, really don't need AC nor even a furnace. But Chavez makes living there pure hell, can't win. And auto parts are unreasonable, 700 US bucks to change three belts in a car!
Caracas sucks, smells like my sealed garage if my vehicle develops a fuel tank leak. Down in a hole, there you find plenty of AC.
Air conditioning can help to relieve asthma and other respiratory symptoms, it is important to maintain your unit properly to avoid excess moisture around the unit itself, which can harbor bacteria and fungi. A poorly maintained air-conditioning unit, or an old one, can send those bacteria and fungi right into your airways. So maintain your AC.
