Relative humidity above 70% (and even lower at special conditions) may for normal living conditions cause condensation on cold surfaces - causing mold, corrosion and moisture related deterioration.
For humans relative humidity below 25% feels uncomfortable dry. Relative humidity above 60% feels uncomfortable wet. Human comfort requires the relative humidity to be in the range 25 - 60% RH.
