Why do we not feel the weight of our brain?

Despite the human brain weighing about 1.4 kilograms, we don’t feel its weight because it’s cushioned and suspended in cerebrospinal fluid (CSF) within the skull. This fluid acts like a shock absorber and creates a buoyant environment, reducing the brain’s effective weight to just a few grams. It prevents the brain from pressing down on nerves or blood vessels, allowing it to “float” safely inside the skull. This clever natural system protects the brain and ensures we stay unaware of its actual heaviness.#brainfacts #neuroscience #cerebrospinalfluid #brainanatomy #humanbodywonder #mindblown #brainfunction #brainfloats
