  We study a model where quintessence potential $e^{-\xi\phi}$ coupled to Higgs
potential. We calculate the evolution of the quintessence, and track the
running of the effective Higgs self-coupling. We find it slightly larger than
that of the standard model in the past. Requiring the electroweak vacuum to be
absolutely stable in inflationary era, we find a lower bound $\xi> 0.35\pm
0.05$, where the uncertainty is mainly from the measurement of the top quark
mass. This lower bound, together with the upper bound from the observation for
dark energy $\xi\lesssim0.6$, narrows down the parameter space and makes it
possible to test this model in the near future. Interestingly, the bound on
$\xi$, if actually shown to be the case by observation, supports the recently
proposed Swampland Conjecture.
