Most of the people start sweating when they eat highly spicy food. This is because the temperature of the body rises while eating anything spicy like chilies. The rise in body temperature happens due to a spicy reaction that occurs on your tongue because of a chemical known as capsaicin. This chemical is present in spicy food items and can cause the generation of heat. Thus, your tongue faces that sensation of that heat. The heating up of any body part makes the sweat glands release sweat.
