Hibernation sickness was the term given to a collection of temporary side-effects following a being's removal from long-term suspended animation. Hibernation sickness could include temporary stiffness, muscle weakness, numbness, deafness and blindness (or, on the other end of the scale, hypersensitivity), and/or confusion. The symptoms rarely lasted for more than a day, and even more rarely caused death. Han Solo suffered from hibernation sickness after being rescued from carbonite by Leia Organa.
However, beings undergoing short periods of suspended animation could suffer no ill-effects, as evidenced during the Clone Wars when Ahsoka Tano, Obi-Wan Kenobi, and Anakin Skywalker used carbonite freezing to infiltrate Separatist lines.
