The Vagus Nerve, Plainly

Theo Grant

A single nerve runs from brain to gut, quietly shaping how calm or rattled you feel all day. This is a clear look at that wandering pathway: what it actually does, why it matters for digestion, mood, and recovery from stress, and the simple, low-effort practices, like slow breathing and cold exposure, that seem to tone it over time. Grounded, clear-eyed, and never overblown.
