Why Do We Get ‘Chillies’ from Spicy Food?

Imagine your mouth is like a detective, and spicy food has a secret message. That message is called capsaicin, which tells the detective (your brain) that something hot is happening, and you feel it as 'chillies'.

Capsaicin makes your mouth think it's burning, even though it's not real fire. Your brain gets confused and sends a message to your body: ‘It’s hot!’ That’s why you get the ‘chillies’ feeling.

When you drink water, it doesn’t help much, capsaicin is oily, so it sticks around. But if you eat something creamy or sweet, like milk or chocolate, that helps your brain forget about the spicy message.
