Why Water Matters
Even healthy eaters often underestimate the importance of their water intake and wind up suffering from chronic, low-grade dehydration. Here are just a few reasons good hydration is essential to good health, followed by six tips for staying hydrated:
Energy: Suboptimal hydration slows the activity of enzymes, including those responsible for producing energy, leading to feelings of fatigue. Even a slight reduction in hydration can lower metabolism and reduce your ability to exercise efficiently.
Digestion: Our bodies produce an average of 7 liters of digestive juices daily. When we don’t drink enough liquid, our secretions are more limited and the digestive process is inhibited. (Note that drinking too much water all at once, particularly with food, can also dilute digestive juices, reducing their efficacy and leading to indigestion.)
Regularity: As partially digested food passes through the colon, the colon absorbs excess liquid and transfers it to the bloodstream so that a stool of normal consistency is formed. When the body is low on water, it extracts too much liquid from the stool, which then becomes hard, dry and difficult to eliminate. Slowed elimination contributes to bodywide toxicity and inflammation.
Blood Pressure: When we are chronically dehydrated, our blood becomes thicker and more viscous. Additionally, in response to reduced overall blood volume, the blood vessels contract. To compensate for the increased vein-wall tension and increased blood viscosity, the body must work harder to push blood through the veins, resulting in elevated blood pressure.
Joint Health: Dehydrated cartilage and ligaments are more brittle and prone to damage. Joints can also become painfully inflamed when irritants, usually toxins produced by the body and concentrated in our blood and cellular fluids, attack them, setting the stage for arthritis.
Aging: The normal aging process involves a gradual loss of cell volume and an imbalance of the extracellular and intracellular fluids. This loss of cellular water can be accelerated when we don’t ingest enough liquids, or when our cell membranes aren’t capable of maintaining a proper fluid balance.
6 Hydration Tips
1. Start each day with a glass of water (no ice). Drink it down before you have coffee, tea or juice. It will help replace fluids lost overnight and get your hydration efforts off to a good start. Also fill a water bottle you can take with you in the car, or keep with you and refill during the workday.
2. Eat two or three servings of fruits and vegetables at every meal. They are brimming with water and include the minerals that help your body absorb and use it properly. Keep in mind that most processed foods (including sugars, flours, salty snacks and processed meats) result in a lowering of the body’s water table. Eating a lot of meat puts pressure on your kidneys and tends to increase your body’s need for water.
3. Establish regular water breaks, if possible. Tailor your drinking to meet your needs. For instance, drink an extra glass of water if you worked out or didn’t squeeze enough fruits and vegetables into your day.
4. Substitute sparkling water and low-sodium vegetable juice for soda and fruit juice. While it’s true that all beverages count toward your daily tally, the sugar in regular soda and fruit juice, as well as the chemicals in diet versions, can trigger a host of unwanted reactions in the body, including blood-sugar spikes.
5. Install water filters in your home and use a pitcher-type filter at the office. Resort to bottled waterwhen you must, but beware of the drawbacks: It’s expensive and environmentally wasteful, the plastic contains harmful chemicals that can leach into the water, and there are no guarantees that bottled water is any better for you than the water flowing from the tap.
6. Cook with high-quality sea salt. A good, unrefined sea salt is rich in trace minerals, which are key to cell health and hydration. Bonus: Sea salt is also lower in sodium than table salt.
