One of the most popular health trends over the last few years has been staying as hydrated as possible, evidenced by the massive popularity of 40-oz Stanely Quencher cups. The theory among those who obsess over hydration is that, when you pee clear, you’ve removed all the waste in your body and are enjoying the incredible benefits of being 100% hydrated. Congratulations.
However, according to Dr. Sermed Mezher, an NHS doctor in the UK, peeing clear isn’t always a sign of being healthy.
“If you’re peeing clear, that means you’re having more than 2.5 liters (85 ounces) of fluid per day, which means your kidneys are working overdrive to keep that water off your brain,” Dr. Mezher said. He goes on to add that when kidneys can’t keep up with their water intake, it can cause water intoxication, which can lead to dangerous, even lethal, brain swelling.

According to Dr. Mezher, it’s all about finding balance when it comes to hydration and the goal shouldn’t be to pee clear all the time. “Of course, like most things in life, too much is not great, and too little isn’t either,” he continued. Two liters (68 ounces) [of water] is good for a healthy adult, and babies under six months shouldn’t be given any water at all.”
The news came as a bit of a shock to some folks in the comments. “One minute it’s not enough water, the next it’s too much… I’m tired,” Tiyana wrote. “I always thought the goal was clear,” Mountain Witch added.
