Why Do Spicy Foods Cause Runny Noses?

define

One of the things you may have noticed is that after enjoying a meal of spicy foods, your nose begins to run. Most people agree that spicy foods cause runny noses. What is the connection between runny noses and spicy food? Here are some of the things you should know about spices and how they can make an impact on your health, including runny noses.

Spicy foods cause runny noses for one simple reason: they contain the chemical capsaicin, which causes inflammation in the nerves and elevates the production of mucus in the nasal membranes. This leads to an increase in the draining action of the nasal passages. While the result may not be aesthetically pleasing, there are actually a number of reasons why this may be a good thing for your body.

One scenario in which it is a good thing that spicy foods cause runny noses is when you have a cold. For many people, one of the worst conditions associated with the common cold is a stuffy nose. While it is possible to take a decongestant and get some relief, the fact is the effect will not last all that long and will not do much for your general well being. Instead, send out for a spicy curry. The spices in the curried dish will not only provide your body with some much needed nutrients, but the heat from the spices will act as a natural decongestant, bringing relief quickly without any side effects at all. With a full tummy and the ability to breathe temporarily restored, it is much easier to get the sleep needed to get over a cold.

The fact that spicy foods cause runny noses is also a sign that your body needs to expel excess mucus. They help the veins and arteries in your body to open up and begin to flush out elements that could eventually lead to blockages in your system. This natural phase of house cleaning helps to keep your body in much better operating condition. Spicy foods are nature’s way of allowing the body to perform general maintenance, ensuring fewer health issues and promoting quicker recovery.

Just because spicy foods cause runny noses does not mean that every time you have a spicy dish that your nose is going to run like a water faucet. Basically, if there isn’t much that needs to be expelled from the body, then there will not be much in the way of nose running. While it is true that no one is fond of having a runny nose, the fact is that many people report being able to breathe more clearly and feeling less head congestion after a plateful of hot Thai noodles and a few moments of wiping the nose. In short, the health benefits far outweigh the inconvenience of a couple moments of a runny nose.

Keep in mind that because spicy foods cause runny noses, your body is able to deal more effectively with maintaining a proper balance and you in turn enjoy a stronger sense of well being.

Capsaicin binds to TRPV1 in your nervous system. This protein is an ion channel for Calcium ions and is temperature sensitive (active above body heat). Capsaicin binds to this protein, which drops the temperature it will work at. To alleviate this perceived "heat" the blood vessels in your periphery (ie. your nose) will move toward the surface and dilate, becoming more permeable. Because it is more permeable, it is more likely to leak fluid (ie. the nose run). The reason why it doesn't run every time you eat a spicy dish is because you can build up a tolerance to the receptor, requiring more capsaicin to achieve the same effect. If the dish isn't spicy enough, no nose run.
