Huberman Lab Clips(@HLPClips):Drinking too much water can kill you: - Take in a lot of water in a short period and you excrete sodium fast enough to disrupt kidney function - Drop extracellular sodium low enough and neurons stop firing action potentials, the signals behind every breath, word and movement - This has happened to people over-hydrating after sports events with fluid that had no electrolytes - Extra sodium won't make your neurons work better, but too little guarantees they work worse. That's why dehydration brings confusion, dizziness and poor coordination. @hubermanlab
