Since dehydration is caused by a loss of fluids, fluid intake is the fastest, best way to treat it. Mild dehydration can be treated at home by drinking fluids such as water (the best fluid choice), sports drinks, oral rehydration solutions such as Pedialyte, juices diluted with water, decaffeinated tea, milk, breast milk for babies, soups, and Jell-O and ice cream.

Dehydration is a symptom that occurs when the body loses more fluids than it takes in, and as a result the body does not have enough water to function normally. 

About 80% of people's total water comes from drinking water and the other 20% comes from the foods we eat. The U.S. National Academies of Sciences, Engineering, and Medicine recommends an adequate daily water intake from all beverages and foods of:

  • 2.7 liters (91 ounces) of total water for women
  • 3.7 liters (125 ounces) of total water for men

People who are physically active or who live in hot climates may need to consume more water.
