Meditation practices activate the parasympathetic nervous system and reduce sympathetic nervous system activation.

“The other thing that works really well is meditation, so I'm talking about naps, but I'm also talking about yoga nidra, which is sort of a form of meditation, and then more standard forms of meditation, all three of those do something powerful which is that they bring our mind into a state of less so-called sympathetic nervous system activation, go back and listen to episode one if that doesn't make any sense, which is what governs your alertness, and instead, it activates cells and circuits in your body that promote the parasympathetic nervous system, or the calming system.”
