In this work, we investigate the chemical and kinetic nonequilibrium dynamics of the Higgs boson during the primordial Universe Quark-Gluon Plasma epoch 
. We show that the Higgs bosons are always out of chemical abundance equilibrium with a fugacity 
due to virtual decay channels. Additionally, Higgs momentum distribution is found to be “cold” for 
GeV, since the scattering rate drops below the production rate.
