In this segment, the presenter explains the physiological cascade that occurs when eating spicy food. Capsaicin, the active compound in chili peppers, binds to the TRPV1 (vanilloid) receptor on the tongue, which sends a signal to the brain. In response, the brain releases norepinephrine and other catecholamines—stress hormones that trigger sweating, tearing, and also travel down the neck to stimulate brown adipose tissue. This chain of events links the sensation of heat from capsaicin to the body's thermogenic and stress responses.

when you put it in your mouth and it starts to create the burn, the zing, capsaicin's activating a receptor, a switch on your tongue. And there's even a scientific name for it. It's called TRPV1. That's called the receptor TRPV1, vanilloid receptor R1. TRPV1 on your tongue is a receptor for capsaicin, the molecule from chili peppers that causes the burn, the heat. And when capsaicin activates that trigger on your tongue, the TRPV1, your tongue sends a signal to your brain and your brain begins releasing norepinephrine and catecholamines. These are the stress hormones. And, and by the way, catecholamines, stress hormones will cause you to sweat, what causes you to tear up. But what's interesting is the catecholamines, they're neurotransmitters, also run down from your brain to the sides of your neck and they activate your brown fat.
