Why Do We Sleep Under Blankets?

If you’re one of those people who sleeps with a sheet even on the hottest of nights, you’re not alone. Plenty of people can’t fall asleep if they aren’t covered with something, even if it’s the lightest of blankets. Why? Dan Nosowitz at Atlas Obscura reports that it’s both physiological and behavioral, and may have a component of simple conditioning.

Surprisingly, he found, sleeping with blankets is a relatively new phenomenon. Historically, blankets were expensive. Through the Middle Ages, Europeans only owned blankets if they were very wealthy. They were so precious, in fact, that bedding was passed down in people’s wills. Instead of snuggling up with a fluffy duvet, most people slept in the same bed as the rest of the household, farm animals included, to keep warm. But as fabric became cheaper and blankets more accessible, they became more commonplace household items. Now, even in tropical places, many people cover themselves with at least something during the night, with the exception of some nomadic cultures near the equator.

Part of the reason is that the body really does need extra warmth at night. Your body’s internal temperature begins to cool down before you go to bed. That’s one reason why some sleep experts recommend taking a bath or shower before bed, since your body will naturally cool off afterward, signaling to your body that it’s time to drift off. (Sticking one foot outside the covers can help, too.) Later in the night, though, that cooling off gets less pleasant and more, well, cold. During REM sleep, your body can’t regulate its own temperature. And for the most part, people tend to be in the REM stage of sleep right around dawn, when temperatures are the coldest. So we naturally learn that even if it’s pretty hot when we go to bed, we’ll wake up shivering at 4 a.m. if we don’t have a blanket.

And then there’s the neurological reason: Weighted blankets have been found to decrease anxiety and stress, because gentle pressure can stimulate serotonin production. Serotonin has been found to help modulate sleep regulation, which is part of the reason that depression and insomnia are linked—when you’re depressed, your serotonin levels are low.

There are more simple psychological reasons to cover up, too. When you’re a baby, your parents put blankets on you when you sleep, so you’re conditioned throughout your early years to associate blankies with bedtime. Above all, maybe we just all want to be swaddled forever. Doesn't that sound nice?

Before you go out and spend hundreds—if not thousands—of dollars on a new mattress, you may want to turn to Amazon. According to Esquire, one of the most comfortable mattresses on the market isn’t from Tempur-Pedic, Casper, or IKEA. It’s a budget mattress you can buy on Amazon for as little as $102.

Linenspa's 8-inch memory foam and innerspring hybrid mattress has more than 24,000 customer reviews on Amazon, and 72 percent of those buyers gave it five stars. The springs are topped by memory foam and a quilted top layer that make it, according to one customer, a “happy medium of both firm and plush.”

Perhaps because of its cheap price point, many people write that they first purchased it for their children or their guest room, only to find that it far exceeded their comfort expectations. One reviewer who bought it for a guest room wrote that “it is honestly more comfortable than the expensive mattress we bought for our room.” Pretty impressive for a bed that costs less than some sheet sets.

Getting a good night's sleep is vital for your health and happiness, so do yourself a favor and make sure your snooze is as comfortable as possible.

The mattress starts at $102 for a twin and goes up to $200 for a king. Check it out on Amazon.

Why Are Decaf Coffee Pots Orange?

The orange spout and handle on a decaf coffee pot have saved many caffeine lovers from having a terrible morning. Like the orange on a traffic cone, the color has become a signal both to the people who drink coffee and the servers who pour it. But the shade wasn't merely chosen for its eye-catching qualities; orange is a piece of branding left over from the original purveyors of decaf java.

According to The Cubiclist, decaffeinated coffee first arrived in America via the German company Sanka. Sanka (a portmanteau of the words sans and caffeine) sold its coffee in stores in glass jars with orange labels. The bright packaging was the company's calling card, and because it was the first decaffeinated coffee brand to hit the market, consumers started looking for the color when shopping for decaf.

In 1932, General Foods, which has since merged with Kraft, purchased Sanka and got to work promoting it. To spread the word about decaf coffee, the company sent orange Sanka coffee pots to coffee shops and restaurants around the country. Even if the waitstaff wasn't used to serving two types of coffee, the distinct color of the pot made it easy to distinguish decaf from regular.

The plan was such a success that orange eventually became synonymous not just with Sanka, but all decaf coffee. Other coffeemakers began offering decaffeinated alternatives, and when marketing their products, they chose the color Sanka had already made popular.

The reason for the orange coffee pot is just one of decaf's not-so-mysterious mysteries. Here's some of the science behind how exactly coffee makers get the caffeine out of the beans.
