Why do chillies do to the body to make us hot and sweat?

Chilli peppers contain a compound called capsaicin, which is responsible for the hot and spicy sensation when consumed. Capsaicin stimulates the heat and pain receptors (nociceptors) in our mouths and on our skin, creating the perception of heat or burning. When we eat spicy foods containing capsaicin, our bodies respond to the perceived heat by initiating a cooling response, which is why we may start to sweat. Sweating is a natural process our bodies use to regulate temperature. As the sweat evaporates from our skin, it helps to dissipate the heat and cool us down. Additionally, the consumption of capsaicin triggers the release of endorphins, the body's natural painkillers. Endorphins create a feeling of pleasure or mild euphoria, which is one reason why some people enjoy eating spicy foods despite the initial discomfort. It is important to note that the heat sensation experienced when consuming chilli peppers is a perceived sensation and not actual physical heat. Capsaicin does not cause actual tissue damage unless consumed in extremely large quantities or if it comes into contact with sensitive areas, such as the eyes.
