ELI5: Why does eating spicy food help unblock a congested nose?
gpt
so your nose has mucous membranes in it that make mucous, the watery stuff in your nose. then there’s spicy food, which has chemicals in it that upset the membranes when you eat it. when upset, the membranes produce more mucous to try to get rid of the chemicals. this causes your nose to be runny, clearing both the chemicals and snot in your nose.
