We use improved propagators including resummation of hard thermal loops and the thermalization rate is computed at the one-loop level in the high temperature approximation. We find that the damping is typically dominated by scattering with gauge bosons, resulting in a damping rate of about $γ_{\Ht}\simeq 0.025T$, $γ_{\Wt}\simeq 0.065T$. The contribution from scattering with scalars is relatively small. Implications for baryogenesis are also discussed.10 pages LaTEX, 1 ps figureHigh Energy Physics - Phenomenologytext
