Feeling weary, sluggish ... perhaps with a headache nagging at you?

Maybe all you need is a drink of water, maybe two or three.

"Water is your body's principal chemical component and makes up about 60 percent of your body weight," the Mayo Clinic says, adding ...

"Every system in your body depends upon water. For example, water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.

"Lack of water can lead to dehydration, a condition that occurs when you don't have enough water in your body to carry out normal functions. Even mild dehydration can drain your energy and make you tired."

MindBodyGreen, whose mantra is "Don't medicate, hydrate," elaborates further ...

"Since your brain is mostly water, drinking helps you to think, focus and concentrate better and to be more alert. As an added bonus, your energy levels are also boosted."

MBG points out that water also keeps your skin fresh, soft glowing and smooth, that it boosts the immune system, that it helps prevent and relieve headaches, that it keeps your joints and muscles lubricated and that it is "essential for your digestive system.

How much water does a healthy adult need?

To simplify things, The Mayo Clinic says ...

"Drink at least eight 8-ounce glasses of fluid a day, because all fluids count toward the daily total."
