The shocking amount of water you should drink each day

How much water should you drink daily? We always hear about the 8x8 rule; that we should drink eight 8-ounce glasses a day. However, there’s no good scientific data to back that up.

Take it from 'Live Science' and Dr. Oz. How much water you really need is different for men and women.

Women should aim for 91 ounces or 2.7 liters per day, while men should have 125 ounces a day or 3.7 liters. That’s according to the National Academies of Sciences and it includes food and drink.

Twenty-five percent of the water in your diet can come from food, such as watermelon and strawberries. Those fruits are more than 90 percent water by weight, says the USDA.

However, these are just drinking guidelines. Everyone’s needs are different. Your body will let you know.

The more you sweat, the more you’ll have to replenish, and the darker the stream, the more water you’ll need.

Sorry if that last tip just ruined your appetite!

5 reasons you should never drink out of a plastic water bottle

They can release harmful chemicals into your water

Plastics are made to withstand a variety of temperatures -- but at a cost. The hotter the bottle gets, the more potential there is to release chemicals known to cause diseases like cancer, especially if you use them over and over again. 


Chemicals in the plastic may make having a baby more difficult

Those same chemicals in the plastic, like BPA, could make having a baby more difficult by affecting fertility. Researchers found that men and women undergoing in-vitro fertilization who had high levels of BPA in their blood, urine, and work environment were less likely to have a successful pregnancy. This is according to a 2013 review of 91 studies published in Reproductive Toxicology


It could raise your risk of heart disease and other circulatory issues

Humans exposed to the highest levels of BPA have an increased risk of heart disease, according to a 2012 study published in Circulation. Researchers think this could be due to BPA's link to high blood pressure. 


Refilling plastic bottles may expose you to harmful bacteria 

Both reusable and disposal plastic bottles break down from regular use over time, meaning that even teeny cracks can welcome in bacteria, according to an article published in journal Practical Gastroenterology. And while most bacteria is usually harmless, bottles can harbor norovirus-, cold-, and flu-causing bacteria. And while usually we'd advise you to wash with hot water and soap, that could cause the plastic to break down even more!


They're awful for the environment (Duh!)

Many of the bottles are still ending up in the garbage even after they are recycled once. The solution? At home filters. Or bottles made of steel, aluminum or polycarbonate because as they say it’s better to be safe than sorry.
