What's the Difference Between a Button-Up and a Button-Down Shirt?

As you probably already know, collared shirts with buttons running down the middle are typically referred to as either button-ups or button-downs. Some people have a strong preference for one term over the other; others use them interchangeably, believing (erroneously) that they’re synonymous.

Last November, model and author Chrissy Teigen took to Twitter and asked in a poll, “Is it a button up or button down?” Of the 220,000-plus respondents, 66 percent said button-up, and 34 percent said button-down. On the other hand, button-down appears to be the more searched-for term overall, according to Google Trends.

So which one is right? As it turns out, the two terms actually refer to two different garments. The button-down shirt came to be in the late 1800s, thanks to British polo players. Their uniform typically consisted of flannel pants, a wool sweater, and a long-sleeve shirt—all in white. It looked pretty snappy, but the players quickly became irritated by their collars flapping in the wind as they rode around on their horses.

According to Charles Panati’s book on the Extraordinary Origins of Everyday Things, “Players routinely asked seamstresses to batten down their collars, and two buttons became the most popular solution to the problem.” This was called a polo collar at the time, and the style was soon popularized by John Brooks, whose father founded the Brooks Brothers clothing line. (Oddly, polo shirts as we know them today were actually made for tennis, not polo.)

This is all to say that button-down shirts have buttons attached to the collar, while button-up shirts do not. Here’s where it gets a little confusing, though: All shirts with buttons can be called button-ups. However, only some button-ups (the ones with buttons on the collars) can be called button-downs.

As Megan Collins of Style Girlfriend explained it to the Today show, it’s kind of like how “an apple is a fruit, but not all fruits are apples.”

If you ever get mixed up, just keep in mind that the collars of a button-down can be buttoned down. As for their sartorial differences, button-down shirts are less common these days, especially among women's styles. They also tend to be slightly more casual than shirts with free-flapping collars, according to Collins.

If ties aren't your thing, but you're still trying to win style points, you should stick with the more versatile button-up shirt, according to Mainline Menswear.

What's the Difference Between Cement and Concrete?

Picture yourself walking down a city block. The sidewalk you follow may be obscured by shuffling feet and discarded gum, but it’s clearly made from something hard, smooth, and gray. What may be less clear is the proper name for that material: Is it concrete or cement? Is there even a real difference between the two words?

Though they’re often used interchangeably, concrete and cement describe different yet related elements of the blocks, flooring, and walls that make up many everyday structures. In simple terms, concrete is the name of the gray, gritty building material used in construction, and cement is an ingredient used in concrete.

Cement is a dry powder mixture that looks much different from the wet stuff poured out of so-called cement trucks. It’s made from minerals that have been crushed up and mixed together. Exactly what kind of minerals it’s made from varies: Limestone and clay are commonly used today, but anything from seashells to volcanic ash is suitable. After the ingredients are mixed together the first time, they’re fired in a kiln at 2642°F to form strong new compounds, then cooled, crushed, and combined again.

This mixture is useless on its own. Before it’s ready to be used in construction projects, the cement must be mixed with water and an aggregate, such as sand, to form a moldable paste. This substance is known as concrete. It fills whatever mold it’s poured into and quickly hardens into a solid, rock-like form, which is partly why it’s become the most widely-used building material on Earth.

So whether you’re etching your initials into a wet sidewalk slab, power-hosing your back patio, or admiring some Brutalist architecture, you’re dealing with concrete. But if you ever happen to be handling a chalky gray powder that hasn’t been mixed with water, cement is the correct label to use.

Why Do You Stop Feeling Tired As Soon As You Climb Into Bed?

There are few situations more frustrating: After a day spent nodding off at your desk, on the train, and on your couch, you suddenly can't sleep the moment you crawl into bed. It's not that you aren't tired or have insomnia, necessarily. Like a curse designed just to torture you, the sleeplessness only seems to occur when you're in your own bed at home, a.k.a. the place where you'd prefer to do your sleeping.

This maddening problem isn't in your head. According to TIME, many people have more trouble falling asleep in their own beds than they do elsewhere thanks to a phenomenon called learned or conditioned arousal. Conditioned arousal develops when you inadvertently train your body to associate your bed with being awake. In many cases, this results from doing stimulating activities in bed. For instance: If you like to slip under the covers and spend 40 minutes watching Netflix before closing your eyes, you're teaching your brain that your bed isn't for sleeping. That means the next time your head hits the pillow, your body will respond by preparing for the next episode of Friends instead of releasing the chemicals that help you fall asleep. The same goes for scrolling through apps, eating, and even reading in bed.

Doing things that aren't sleeping in bed isn't the only way to develop conditioned arousal. If there are other factors keeping you up at night—like thoughts about your day, or that cup of coffee you had at 8 p.m.—they can lead to the same result. Your brain starts to associate being in bed with tossing and turning all night, so even if those mental and physical stimulants go away, the muscle memory of being awake in bed remains.

Conditioned arousal is a vicious cycle that can't be broken in one night. The only way to manage it, according to the American Psychological Association (APA), is to minimize behaviors that contribute to poor sleep habits and to reserve your bed for sleeping (though sex is OK, according to the APA).

If you're a nighttime scroller, browse apps in a different room before getting into bed, or skip checking your phone at the end of the day altogether. When you spend more than 20 minutes struggling to fall asleep in bed, get up and move to a different part of the house until you get sleepy again; this will stop your brain from strengthening the association between your bed and feeling restless. The results won't be instant, but by sticking to a new sleep routine, you should eventually train your body to follow healthier patterns.

Of course, combating conditioned arousal alone isn't always effective. In people with conditions like anxiety and insomnia, intrusive thoughts and genetic factors can prevent them from falling asleep even under ideal circumstances. In such cases, the help of a medical professional may be required to sleep more soundly.
