Why Do Spicy Foods Make Your Nose Run?

Hot sauces, curries, wasabi peas and other spicy treats turn you into a snot faucet. Why is that?

Capsaicin is the chemical found concentrated in the placental tissue of chile peppers and allyl isothiocyanate is an oil contained in plants like mustard and radishes (including horseradish). Plants use both of these chemicals as biological weapons against predatory animals. They irritate pretty much any soft tissue they come in contact with, which is what causes the wonderful burning sensation on your tongue. But they also cause the painful sting of post-chile-handling eye contact and a seriously runny nose. When your mucous membranes get hit by these chemicals, they become inflamed and go into defense mode. This means producing mucous to trap allergens and other undesirables, and keeping them out of your respiratory system by removing them via the nasal passage.

You might have noticed that if you’ve got a cold and are congested, the runny nose effect of spicy foods can make you feel a little better. Don’t be fooled by the healing properties of hot and sour soup and buffalo wings, though, because the relief is only temporary and really just makes things worse in the long run.

Capsaicin and allyl isothiocyanate’s irritation can cause the dilator naris muscle in your nose to temporarily allow more air to enter. Receptors in your nose then tell your brain that you’re breathing easier. It’s all an elaborate ruse, though, and when the effect of the heat wears off, you’re back to your old stuffy self, with plenty of extra snot brought on by your meal to boot!

Why Are There 10 Hot Dogs to a Pack But Only 8 Buns?

Watching competitive eating champion Joey Chestnut cram dozens of hot dogs down his throat would make anyone crave a grilled log of processed meat this summer. But shopping for hot dogs can be a confusing experience. The dogs are typically sold in packs of 10, but the buns are sold in packs of eight. What's behind this strange dog and bun inequality?

According to the National Hot Dog and Sausage Council—yes, there is a National Hot Dog and Sausage Council—there’s a good reason for the discrepancy. For starters, distributors of hot dogs are almost always different from manufacturers of baked goods like rolls. The hot dogs are sold in packs of 10 because producers of meat (or meat-like) products selected that quantity when hot dogs started to sell at retail grocery stores in the 1940s. Oscar Mayer, which led the charge into direct-to-consumer hot dog packaging, sold hot dogs by the pound in accordance with how meat is typically priced. Having 10 dogs that weighed 1.6 ounces each seemed like the ideal distribution of weight.

Bakeries, meanwhile, have standards of their own. Buns and sandwich rolls are usually sold eight to a pack because the baking trays for the elongated buns are typically sized to fit that number. Two sets of four buns come off the tray, which is the reason why buns are often still attached to one another when you open a bag.

These standards were created independently of one another: Bakeries weren’t too preoccupied with hot dogs when they were settling on a four-roll tray standard, and hot dog manufacturers weren’t thinking about how difficult it would be for bakeries to break from their conveyor system to offer 10 buns to a pack.

It can be frustrating if you buy just one or two packages of each, but if you’re hosting a big enough party, the uneven number doesn’t matter. You just need to buy five packages of buns and four packages of hot dogs to have 40 matching pairs. No complicated calculations required.

When Are the Dog Days of Summer?

The official “dog days” of summer begin on July 3 and end on August 11. So how did this time frame earn its canine nickname? It turns out the phrase has nothing to do with the poor pooches who are forever seeking shade in the July heat, and everything to do with the nighttime sky.

Sirius, the Dog Star, is the brightest star in the sky. The ancient Greeks noticed that in the summer months, Sirius rose and set with the Sun, and they theorized that it was the bright, glowing Dog Star that was adding extra heat to the Earth in July and August.
