Dr. Lena Hartwell, a somatic psychologist who studies body‑based interventions, explains that skin is our largest sensory organ. “We spend 95% of our lives in a textile cocoon,” she says. “That’s not natural. When you expose your full skin to air, sunlight, and natural textures—sand, salt water, breeze—you activate thousands of nerve endings that are usually dormant. That sensory input lowers cortisol and increases interoception—your ability to feel what your body is actually experiencing, versus what you think it should look like.”
