A closer look
Loneliness has absolutely nothing to do with physical proximity to human bodies. In fact, extreme crowding can exacerbate it through the contrast effect. When you are shoved into a dense, fast-moving crowd like Times Square, your brain registers thousands of potential social connections that are coldly ignoring you. This sharp contrast between high social availability and zero meaningful engagement spikes cortisol levels, making the subjective experience of isolation far more painful than standing alone in nature, where the brain does not expect social validation in the first place.
