Why is chilli so addictive?
At the moment you eat chillies your body wants to cool you down and take away the pain caused by the capsaicin in the chilli. Your brain starts to produce endorphins, which is a natural painkiller. And as soon as they kick in you will feel and experience a nice endorphin rush and euphoria. The natural high, this is the main reason you always want more chilli! You will experience the same sensation with sports e.g. jogging. But to my opinion eating chillies is easier and it saves you the hassle of running down the street.
