Your body has an off switch. Most people can't find it.
Your nervous system runs in two modes. Sympathetic - alert, stressed, cortisol high. Parasympathetic - calm, safe, ready to rest.
Magnesium is the mineral that throws the switch between them. It activates GABA receptors - the brain's primary calm signal - and tells your nervous system it's safe to stand down.
When magnesium is low, the switch doesn't throw. Your body stays in sympathetic mode. You lie down. But nothing actually stops.
