  We prove a relation between the scaling $h^\beta$ of the elastic energies of
shrinking non-Euclidean bodies $S_h$ of thickness $h\to 0$, and the curvature
along their mid-surface $S$. This extends and generalizes similar results for
plates [BLS16, LRR] to any dimension and co-dimension. In particular, it proves
that the natural scaling for non-Euclidean rods with smooth metric is $h^4$, as
claimed in [AAE+12] using a formal asymptotic expansion. The proof involves
calculating the $\Gamma$-limit for the elastic energies of small balls
$B_h(p)$, scaled by $h^4$, and showing that the limit infimum energy is given
by a square of a norm of the curvature at a point $p$. This $\Gamma$-limit
proves asymptotics calculated in [AKM+16].
