The Maricopa County Sheriff's Office said Arias was transferred back to the all-female Estrella Jail Monday after doctors determined she no longer posed a threat to herself, The Arizona Republic reported.
Arias, 32, is housed in a cell alone.
She was placed under suicide watch soon after the guilty verdict last week for commenting during a television interview she would rather receive the death penalty than a sentence of life in prison.
Her trial is to resume Wednesday, when the jury will begin deliberating whether she deserves the death penalty in the death of ex-boyfriend Travis Alexander.
A jury found Arias guilty of premeditated murder in the stabbing and shooting death of her former lover.
