How many ounces of water should you be drinking in a day? The answer can vary daily based on your age, activity level and other factors. And there is such a thing as drinking too much water.

As the world celebrates Earth Day on Monday, a sobering reality is that our food and water sources are becoming increasingly contaminated with microplastics and toxic metals. But what can you do about it? Is there a way to keep you and your family safe?

Consumer Reports experts checked out reusable water bottles, and we give the lowdown on the best kind for kids, the gym, and everything in between.

JACKSONVILLE, Fla. – NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the moon. This discovery indicates that water may be distributed across the lunar surface and not limited to cold, shadowed places. SOFIA has detected water molecules (H2O) in Clavius Crater, one of the largest craters visible from Earth, located in the moon’s southern hemisphere. In 2018, SOFIA began detecting water molecules in sunlight through spectral analysis on the moon. Whether the water SOFIA found is easily accessible for use as a resource remains to be determined.

Kobayashi told The Associated Press that he uses H2O to train his stomach to expand. "I have to put something inside the stomach to make it expand, but it doesnt necessarily have to be food," Kobayashi explained. I feel so exhausted and so out of breath, Kobayashi told the AP. Derek Jacobs, who first qualified for the Nathan's contest in 2017, told Men's Health he likes to drink a lot of caffeine prior to competing.
