  In this study, we conducted a detailed analysis of the core parameter of Warm
Higgs Inflation (WHI) $-$ the dissipation coefficient ($Q$). As a crucial
parameter in the warm inflation process, $Q$ exerts profound influences on the
entire evolutionary process. By meticulously deriving the relationships between
various quantities and $Q$, we successfully circumvented the common
preconceptions regarding strong and weak dissipation, laying the foundation for
a more accurate exploration of their interconnections. Taking into account the
constraints imposed by Cosmic Microwave Background, we observed that the
dissipation coefficient $Q$ remains at extremely low levels throughout the
entire warm inflation process, i.e., $Q \ll 1$. This observation indicates that
WHI falls under the category of weakly dissipative warm inflation. Despite
being weakly dissipative, $Q$ still plays a crucial role in the evolution of
temperature, energy, and other quantities, highlighting its significance and
non-negligibility. We delved deeper into the impact of the primordial power
spectrum on the dissipation coefficient $Q$ during the warm inflation process,
discovering that the dependency is not significant. Consequently, this
naturally leads to the unobtrusive dependence of the gravitational wave power
spectrum on $Q$. Finally, we found that gravitational waves generated by WHI
hold the potential for verification in future observational experiments,
especially through the SKA100 experiment. These findings provide a theoretical
support for a more profound understanding of the early evolution of the
universe.
