Everybody knows the adage about drinking eight 8-ounce glasses of water every day, but where did it come from?

According to this NPR article, in 1945, the US Food and Nutrition Board decided that 1 mL of water per calorie was what people needed to stay hydrated. This is approximately 64 ounces of fluid per day. And this stuck.

Per the Mayo Clinic, whats counts as water may surprise you: Any liquid, including foods that are high in liquid, like soups, smoothies, fruits, and vegetables like melons, citrus, and tomatoes, are excellent sources of liquid. This means you don’t need to chug a huge 64-ounce bottle of water every single day. As long as you are consuming foods that are high in liquid, you are getting enough hydration for your body

Too much of a good thing? Yes, you can be overhydrated, and that can cause an electrolyte imbalance, which can lead to cloudy thinking, nausea, vomiting, headaches, and even muscle cramps. This isn’t gonna happen unless you’re drinking over 4 L of water an hour. Overhydration does not happen often, but it can occur.

If you’re looking for ways to add hydration to your day, here are a few ways:

• Add high water, fruits, and vegetables to your diet. This includes melons, tomatoes, lettuce, strawberries, and citrus.
• If water is boring all by itself, try sugar-free powdered drink mixes or fruit-infused water. We have a pitcher similar to this.
• Carry and use a reusable water bottle or cup with a lid. Remember to wash it daily. Yes, even bottles containing water can still harbor bacteria.
