Question

After eating spicy food, why does breathing-in cool my mouth, but breathing-out burns it more?

In: Biology

Answer 1

most spicy foods work by activating a receptor that reflects heat. Imagine if there is a thumb print machine and the thumb that opens it is heat, the spicy food has capsaicin which also has the same thumb print. Basically activating the sensor. When you breath in, the air in ambient which your body is used to. But when you breath out it comes out around 30 degrees C. Which is going to trigger the censor which is partially opened by spicy foods.
