Internal (aka the interoception system)
This sense helps you perceive your body’s internal sensations and functions, like hunger, thirst, pain, or discomfort, as well as heart rate, blood pressure, and breathing. The body-to-brain neural channels send information that helps you sense and interpret your internal processes.
How to tune in
• Focus on taking deep breaths and pay attention to how your diaphragm and lungs expand with each breath and how your heart rate slows down.
• Notice closely the signals your body sends when it is time to eat or sleep.
