NEW YORK (CBSNewYork) — Hydration – it’s something we hear about continuously through the summer months.

We know it’s essential to stay healthy and hydrated, especially when the heat is on, but there are a lot of myths floating around out there about how much water we really need to drink, and when.

Kerri Ann Jennins, a registered dietician and the association nutrition editor of “Eating Well Magazine” stopped by The Couch to help us figure it all out.

For starters, you don’t actually need eight glasses of water a day, which is the common knowledge. You need more.

Women actually need nine cups, while men need 13.

“You can get it throughout the day,” Jennins said. “You get about 2 and a half cups of water through fruit each day. You can get it from other beverages as well.”
