She told "Skullduggery," the Yahoo News podcast on Sunday that "increased isolation, depression, anxiety, addiction, and escapism" are the consequences of being on social media too much.
"There are amplified impacts for young people, particularly under the age of 3 with screen time," she told Skullduggery. "But I think it has a lot of effects on older people."
Ocasio-Cortez described her separation from Facebook as a "big deal" because the platform was crucial to her campaign.
Her ability to effectively use social media prompted her to host a jam-packed Twitter training session for other members of Congress in January.
"The top tip, I think, is really to be yourself and to really write your own tweets so that people know it’s you talking," Ocasio-Cortez told ABC News after emerging from class in January.
Ocasio-Cortez is still active on social media, posting to her own Twitter and Instagram accounts, but during the interview with "Skullduggery," she explained she's revamped her lifestyle when it comes to social media use.
"I've started to kind of impose little rules on myself," she said. "I take in consumption and reading during the week but on the weekends I am not scrolling through trying to see what content journalists are writing."
And even though Ocasio-Cortez has decided to stop using Facebook, her personal Facebook page remains active with several campaigns sponsored by "Alexandria Ocasio-Cortez for Congress." One of those ads calls for support of her signature Green New Deal.
