Sip Water—a great way to support hydration.

In the Brain Gym program, since 1986, we’ve included drinking water as one of our key 26 activities. We’re advocates of staying hydrated, as we find that it strengthens so many markers of vitality, attention, and memory. According to the Mayo Clinic(1), “water is your body’s principal chemical component and makes up about 60% of your body weight….Every cell, tissue and organ in your body needs water to work properly.”

Research studies(2) are now finding that states of reduced water intake (dehydration) correlate with fatigue, mood swings, confusion, decreased alertness, increased headaches, weight gain, sleepiness, and more. Some of these effects were found to be reversed in just 20 minutes after drinking some water. In one study(3), half of American children were estimated to be dehydrated, with about one-quarter of them not drinking adequate water on a daily basis.

In Brain Gym: Teacher’s Edition (2010, p.54), we write: “Water is essential to the proper lymphatic function on which nourishment of the cells and removal of waste depends. The average daily water loss for humans through natural body processes (such as urination, respiration, perspiration) is about two and a half quarts (ten glasses). Psychological or environmental stress also depletes the body of water. Scientists have yet to reach consensus regarding the likely need to replace this loss by eating fruits and vegetables, avoiding diuretics and dehydrating food, and drinking a like amount of water. We consider Sipping Water to be an effective way to restore hydration. As with light rain falling on dry ground, water is best absorbed by the body when taken in frequent small amounts.” 

Biologist Carla Hannaford, in her book Smart Moves: Why Learning Is Not All In Your Head, explains that “Our bodily systems are electrical. Ultimately, it is the electrical transmissions within the nervous system that make us sensing, learning, thinking, acting organisms. Water, the universal solvent, is essential for these electrical transmissions and for maintaining the electrical potential within our bodies. (2010, p.151)” 

The Mayo Clinic comments on water needs by saying: “You’ve probably heard the advice, ‘Drink eight 8-ounce glasses of water a day.’ That’s easy to remember, and it’s a reasonable goal. Most healthy people can stay hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than eight glasses a day might be enough. But other people might need more.(1)”

In addition, the American Optometric Association reminds us in an article on “Dry Eye” to blink and to drink plenty of water when we’re reading or working at the computer, as staring can be dehydrating to the eyes. 

Finally, here’s a link to a terrific video with Thomas Myers, author of AnatomyTrains: Myofascial Meridians for Manual and Movement Therapists, on why even small movements—shifts in body positioning—can help us better utilize the water that we drink.
