The EPA says it’s a real thing, so maybe it’s time to learn how ventilation and contaminants can make you sick when you stay indoors.

I’m Cristen Conger and you can consider this my letter of protest regarding these horrible working conditions!
That’s right boss, I’m talking about “Sick Building Syndrome.”
The Environmental Protection Agency says Sick Building Syndrome is real. They define it as (and I quote) “a situation where a building’s occupants experience discomforting health effects, even though no specific cause can be found.”
You know what else they say? That 30 percent of all office buildings in the United States could be sick.
That’s not just offices either. SBS is a problem in schools, libraries and even people's homes.
In the United States, the average person spends 80 to 90 percent of their time indoors. You know what else? Offices with mechanical ventilation and without open windows are at more risk.
“Well what are the symptoms?” you might have asked if you cared about my well being,
Headaches, dizziness, nausea, pain, fatigue, shortness of breath, coughing... and irritation of the throat, nose, skin and eyes.
You know what that does? It reduces work efficiency and increases absenteeism.
Let me stop you before you tell me that Tina in Accounting doesn’t have these symptoms, because inhabitants sharing the same office space are known to experience different signs of the illness.
Many people (like Tina) are either misdiagnosed or don’t even seek help. So you better believe public health officials when they say that “seemingly minor complaints” should be taken seriously.
Are we on the same page now? Good, because researchers still haven’t identified a single cause for SBS. Most say it’s likely a combination of things like chemical and biological contaminants, along with poor air ventilation.
See, during an oil embargo in the 1970s, buildings in the U.S. were made more airtight so the nation could conserve energy (and building owners could cut costs).
Sealing up buildings like this reduced ventilation down to 5 cubic feet per minute per person. But! The American Society of Heating, Refrigeration and Air-Conditioning Engineers (yes, that’s a thing) has revised their modern ventilation standards to a minimum of 15 cubic feet per minute per person.
Exterior pollutants like exhaust and plumbing fumes - containing things like carbon monoxide, radon, formaldehyde and asbestos - can all enter through poorly located intake vents.
While inside, we’re circulating volatile organic compounds from adhesives, carpeting, cleaning agents, synthetic fragrances and even copy machines.
What to do, what to do? Well, some governments have established guidelines for acceptable levels of gaseous indoor air pollutants. So you could start by increasing ventilation rates, removing pollutant sources and cleaning the air. The EPA also recommends routine maintenance of HVAC systems.
Some houseplants might help too. A study out of the University of Cologne in Germany found that certain plants can absorb air pollutants.

![Where Did Neckties Come From?
Its one of the vital pieces of attire for business people across the world - but where did ties come from?

It’s weird when you think about ties – imagine describing them to someone who’s never heard of them. Generally speaking, they’re decorative. A tie won’t keep you warm the way a scarf would. And, depending on the material, it’s not going to be a good napkin, mop or towel. We just tie these things around our necks and walk around as if to say “that’s right, world, I’m doing important stuff today”.
Beginning in the early 1600s, both Louis XIII and his successor Louis XIV used Croatian mercenaries during various battles. These mercenaries wore scarves or knotted neckerchiefs as part of their uniforms – finer material for officers, and more coarse for the rank and file. The scarves did have a function, in that they likely helped tie jackets together, but the King was more impressed by the mercenaries’ fashion sense. And he wasn’t the only one.
Over the next few years the scarves – which were called ‘cravates’ or cravats, swept across France. They were more comfortable than the starched linen ruffs that had been the norm, because they were loose and less restricting. As these cravats became more popular with the wealthy, they also became more intricate, with new materials like lace, increasingly sophisticated knots and so on. The cravat soon spread to other countries, earning fans like England’s Charles II.
Of course, at this point there were numerous variations on the original cravat, but these didn’t look like the relatively slim, modern ties we see today. We didn’t even call them ties. During the reign of Louis XIV the original cravat gave way to a variation called ‘the Steinkirk’, which had a single knot and a narrow shape. As the years turned into decades and the decades in centuries, the tie continued to evolve and we created variations like the bowtie.
Here’s a weird tangent: Do you remember the song “Yankee Doodle Dandy”? There’s a part in there where the verse goes “stuck a feather in his cap and called it macaroni”. Turns out that’s more than just a nonsensical rhyme. “Macaroni”, you see, described a specific type of fashion sense, and the men who subscribed to it.
In the late 1700s a group of controversial fashion aficionados known as ‘macaronis’ began tying their neckwear in certain knots and styles to indicate their tastes, which reportedly led to their cravats simply being called ties.
There are hundreds of other interesting things about ties aside from their evolution, which continues today. You can thousands of sources telling you how, where and why a tie should be worn a specific way – as well as why it shouldn’t. While their popularity may wax and wane over the decades, which is the case with most fashion accessories, it seems that ties – or something like them – are here to stay.
