Why does Spicy food Burn our Tongue? | #aumsum #kids #education #science

AumSum was enjoying a plate of noodles, when he took a big bite with bright red chilies hidden inside. Instantly, his tongue felt like it had caught fire. His eyes widened, his face warmed up, and he reached for water in a hurry. Shocked, he wondered - Why does Spicy food make our Tongue Burn? Determined to find out, AumSum shrank and entered his own tongue. He landed on a bumpy landscape filled with tiny structures called taste buds. Each taste bud had special cells that sensed flavors like sweet, salty, sour, and bitter. AumSum expected to find a spicy sensor too, but there was none. Instead, a chemical from the chilies, called capsaicin, was spreading across the tongue. AumSum followed the capsaicin as it attached itself to special nerve endings. These nerve endings were not for taste at all. They usually sensed pain, heat, and touch. When capsaicin touched them, they reacted strongly. He watched as these nerves sent powerful signals rushing toward the brain. The brain received the message and immediately got confused. The signals were the same ones that appeared when the tongue touched something hot. So, the brain decided the tongue must be burning. The brain triggered a warm, fiery sensation to warn the body, making AumSum feel the burn even though nothing was actually burning. Smiling proudly, AumSum now understood the mystery.
