I.
What it is

The short version.

The hormonal surges of puberty (testosterone, estrogen, and others) act directly on the brain's emotional and social circuits. They heighten sensitivity to status, attraction, and threat — which is part of why early adolescence can feel like an emotional storm. The intensity is real but usually temporary — as the hormonal system steadies, the emotional swings tend to even out.
