Are hot chili peppers addictive? Why we enjoy eating hot chili peppers

Chili peppers are not addictive, but people enjoy the feeling they from eating eating hot chili peppers

The chili peppers contain an oil called Capsaicin. It activates pain receptors ('trigeminal cells') that sense the acid and burning sensation. These receptors are located throughout the mouth nose and throat. The trigeminal cells send pain signal to the brain. The brain responds by releasing endorphins. Endorphins give a feeling of euphoria, a pleasure sensation, or a 'High'. Some people may not be addictive to chili peppers but look forward to this pleasure.

Simultaneously, the body responds with increase in heart rate, metabolism, mouth salivation, and sweating. The nose starts to run. The stimulation of saliva increases the palatability of starchy foods. Chili pepper heighten the mouth's sensitivity so the foods appear more flavorful and taste better than they actually are.

The red pigment in the chilies gives aroma, and the sugar content adds to flavor.
