Why does curry make your nose run?

Curry often contains spices like chili peppers, which contain capsaicin, that can irritate the mucous membranes in the nose. This irritation triggers a response from the body to produce more mucus, leading to a runny nose. Additionally, the strong aromas of spices can stimulate the nasal passages, further contributing to this effect. Overall, the combination of heat and strong scents can evoke a physical reaction resulting in a runny nose.
