the body's way of bragging without saying a word
means Radiating light or warmth, or looking healthy and radiant — often used for skin, faces, or praise so positive it practically shines.
from From Old English 'glowan,' to shine with heat, part of a glittering family of 'gl-' words in English — glow, gleam, glimmer, glisten, glint — many tracing back to a Proto-Germanic root for brightness. The figurative sense of a person 'glowing' with health, happiness, or pride is much later, borrowing the heat-and-light image to describe a face that seems lit from within.
