That tingling feeling of the tongue and the less-than-pleasant runny nose that accompanies a delightfully spicy treat can all be chalked up to science. According to Live Science, hot peppers are loaded with capsicum, a debilitating irritant that inflames the lining of your mucous membranes. These membranes then respond by attempting to flush out the irritant in a sea of mucus that presents as a runny nose.

However, not all spicy foods contain peppers. Condiments like wasabi and horseradish contain an oil known as allyl isothiocyanate, which is equally irritating to your nostrils. Time reports that Dr. Brett Comer of the University of Kentucky College of Medicine described the phenomenon this way: "when your mouth or throat encounters any foreign object that's noxious, the thinking is that liquid helps to move that out."

Moving it out, for most people, means a pesky, runny nose. For some people who are extremely intolerant, this reaction can also cause an upset stomach or even runny diarrhea.
