Considering how important hydration is, it’s astounding how much misinformation is out there about it. Have you noticed the uptick in humans lugging around enormous jugs of water—jugs half the size of their body—that they force themselves to consume every day? Yeah, they don’t really need to do that. Have you noticed how often, if someone has a headache, a stomachache, or any sort of symptom, friends will tell them “You’re probably just dehydrated?” Somewhere along the lines, all of these myths started to spread about hydration, and they wound up spreading like wildfire. Of course, nobody would come around with jugs of water to put the wildfire out because they were too busy guzzling all of it. Here are myths and truths about hydration you should know.

Myth: Eight glasses a day is essential

This is actually a myth started by mega food company Danone a long time ago, to get people to purchase more of their products. They own Evian and Volvic water, to name a couple. So, from there, people started pouring themselves eight glasses of H2O a day—whether they felt thirsty or not.

Truth: There is no exact number

The amount of water you need every day will depend on a lot of things, including your age, weight, activity level, medications, health conditions, and other factors. Eight glasses can be too many for some, and far too little for others. Your doctor can help you land upon an accurate number for you.

Myth: Death by dehydration is a real risk

One reason people got on board with the eight-glasses-a-day myth was stories of people who have died from dehydration. There’s nothing like little scare tactics to get people running to the store to clear water jugs off of the shelves.

Truth: Yes you do—that’s what thirst is for

So, we have thirst for a reason: it lets us know when our hydration levels are getting low. We do know when we’re dehydrated. We may be unaware for, say, a couple of hours, but our bodies will let us know soon enough.

Truth: Other factors could be at play

If you drink plenty of water and don’t feel thirsty, then your yellow pee is probably nothing to worry about. It’s actually very rare to have clear pee, all of the time. And things like vitamins can contribute to yellow urine.
