- Our bodies are really good at regulating our internal temperature. One of the main ways it does this is through sweat.
- In the case of hot beverages, it’s through the temperature receptors in the stomach. The hot beverage hits the stomach and your internal temperature increases about .5 degree Celsius (about 1.5 degrees Fahrenheit). The body says “I’m heating up – I need to cool down”. To cool down, you start to sweat.
- With spicy foods, the end result is the same – increased sweating. But this time, it’s the receptors in the mouth that send the signal to the body that the temperature is rising. This is “gustatory sweating”.
