Chewing increases heart rate primarily through the activation of the autonomic nervous system. When you chew, the body initiates a digestive response, leading to the release of hormones and increased blood flow to the digestive organs. This process can stimulate the sympathetic nervous system, which can elevate heart rate as part of the body's overall response to prepare for digestion and nutrient absorption. Additionally, the physical activity of chewing can also contribute to a slight increase in heart rate.
