Honeydew melons, cantaloupe, watermelon, and even oranges are just some of the foods that are hidden sources of water.
"Some foods are over 90% water, so foods such as iceberg lettuce, spinach has a lot of water, asparagus has a lot of water and then, some of our fruits," Kristin Kirkpatrick of Cleveland Clinic said.
Iceberg lettuce is 96% water and contains potassium and foliate.
Watermelon can also get fluid back into your system on a hot, sunny day. It's 90% water and contains cancer fighting antioxidants.
Eating grapefruit at breakfast will help hydrate you because grapefruit is 90% water and packed with vitamin c.
Veggies have less water than fruit, but cucumbers and broccoli are high-water content vegetables, and if you're looking for something a little different, try re-hydrating with some kohlrabi.
"Kohlrabi is both high in folate, as well as high in water content. So, kohlrabi is a great source for us to get a little bit of hydration, Kirkpatrick said.
