Why does alcohol burn your throat?

In: Biology

Short answer: You are feeling your own body heat.

Long answer…

Your body has nerve endings that detect changes in heat. When alcohol comes into contact with your mucous membrane (the skin on the inside of your mouth, nose, and throat), it has an effect on these nerves that makes them trigger at a much lower temperature than normal, which happens to be lower than the temperature of the inside of your mouth. So the nerves are reacting to your own body heat, telling your brain it’s too hot.

Alcohol is very fond of water. It’s sucking the water out of the cells that line your mouth and throat, which kills them. When the nerves are affected they scream to the brain for help, but help never comes until the glass is empty.
