How much fluid should I drink per day?

The National Academies of Sciences, Engineering, and Medicine determined (‎5) that an adequate daily fluid intake is about 15.5 cups (3.7 liters) of fluids for men and about 11.5 cups (2.7 liters) of fluids a day for women. These recommendations cover fluids from water, other beverages and food. (About 20 percent of daily fluid intake usually comes from food and the rest from drinks.)

What kind of water should I drink?

Experts recommend drinking purified water, enriched with minerals (‎19) and preferably not from plastic bottles. Plastic drinking bottles contain many chemicals (‎10), that can leach into the bottled water, especially when exposed to heat or when the bottle is old. Different types of plastic can release chemicals that can pose a threat to the human body. The composition of plastic includes carcinogenic and other substances such as bisphenol-A and phthalates, some of which interfere with hormones in the body, as well as compounds the dangers of which are still poorly understood.

Water Dos & Donts


Bodily health, most importantly of the brain, is highly dependent on maintaining a steady and adequate intake of water. The purity of the water is another important aspect, both in taking-in essential minerals and in keeping-out toxic substances that can seep in to the source, such as when stored in plastic bottles or transported in deteriorating pipes. The temperature of the water when being drunk is also important, with clear benefits for cool, pure water. And as important as this is for adults, it is even more vital for children!
