  We propose that the spectrum of the surface area of the apparent horizon (AH)
of de Sitter (dS) spacetime leads to corrected temperature and entropy of the
dS spacetime, offering new insights into its thermodynamic properties. This is
done by employing the spectrum of the AH radius, acquired from the
Wheeler--DeWitt (WDW) equation, together with the Stefan--Boltzmann law, the
time-energy uncertainty relation, and the unified first law of thermodynamics.
