  I consider the Festina Lente Swampland bound and argue taking thermal
effects, as for instance occur during reheating, into account significantly
strengthens the implications of this bound. I argue that the confinement scale
should be higher than a scale proportional to the vacuum energy, while Festina
Lente without thermal effects only bounds the confinement scale to be above the
Hubble scale. For Higgsing of nonabelian gauge fields, I find that the
magnitude of the Higgs mass should be heavier than a bound proportional to the
Electroweak scale (or generally the scale set by the Higgs VEV). The measured
values of the Higgs in the SM satisfy the bound. A way to avoid the bound being
violated during inflation is to have a large number of species becoming light.
If one wants the inflationary scale to lie below the species scale in this
case, this bounds the inflationary scale to be $\ll 10^5$ GeV. These bounds
have phenomenological implications for BSM physics such as GUTs, suggesting for
example a weak or absent gravitational wave signature from the GUT Higgsing
phase transition.
