Why Does Bad Weather Aggravate Old Injuries?

Reader Jen wrote in to ask, “Why do old injuries ache during crummy weather?”

“Oh, my bones are aching. It must be about to rain.” - Everybody’s grandpa, ever.

The idea that certain aches and pains correspond with, and can even predict, the weather is widespread, and has been around since at least the days of ancient Greece.

The typical explanation for bad-weather-related aches is that the drop in barometric pressure that comes with a storm causes soft tissue and fluid around joints to expand, irritating nerves and causing pain, especially at the sensitized site of an arthritic joint or an old injury.

The scientific evidence for the phenomena, which has been studied since the early 20th century, is mixed.

Some studies have found that changes in barometric pressure increased pain, others found that it decreased it, and still others found no correlation. The influence of temperature and relative humidity has also been studied, and is also unclear. (For more on some of this research, see here and here).

A big hurdle to studying the problem is that the swelling happens on such a small scale that it’s difficult to objectively detect and measure, so researchers have to rely on people’s subjective accounts of pain, which aren’t always reliable and are hard to compare from one person to another.

While one study suggests that the phenomena might be explained by psychological factors like people finding a pattern where there isn’t one, and the influence of the “general plausibility and traditional popularity” idea, most of the research on the subject points out that the frequency of reports makes it hard to ignore, and it deserves further attention and research to find a cohesive explanation.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Whether you openly admit it or desperately try to hide it, it’s an undeniable fact that every living and breathing human being farts.

If you do love a good fart joke, you’re in good company. The very first recorded joke, which was written by the Sumerians and dates all the way back to 1900 BCE, was about—you guessed it—breaking wind. And some of the world's great thinkers, from William Shakespeare to J.D. Salinger, have slipped a fart joke (or 10) into their work.

In this episode of The List Show, we're sniffing out 30 fascinating facts about farts—from why humans expel gas to how often the average adult squeezes the cheese. You can watch the full episode below.
