It's not hard to stay hydrated

In the past, it was believed that most people should drink eight eight-ounce glasses of water each day. Today, that recommendation is most often made by the bottled water industry. Studies suggest that women who appear well-hydrated take in about 2.7 quarts of water a day and men about 3.7 quarts of water. However, all sources of fluid can contribute to those total water needs; these sources include juice, soda, coffee, tea, milk,External Hemorrhoids are those that occur below the dentate line. soup, beer, wine and foods that contain water.

The water in foods accounts for about 20 percent of our total water intake. Many fruits and vegetables, such as watermelon and tomatoes, are 90 percent or more water by weight; apples are 84 percent and broccoli 91 percent.

Water, however, has the advantage over other drinks such as beer, wine, sodas, etc., because it is calorie-free, inexpensive, readily available and environment-friendly, especially when it is right out of the tap.

There is no clear evidence of any benefit from drinking increased amounts of water. Drinking lots of water does not improve kidney function or help kidneys eliminate toxins. It does not, as some claim, improve overall health, lower blood pressure, boost concentration in kids, prevent headaches, improve skin tone, or cause weight loss by suppressing appetite. It can, however, help with weight control if water is substituted for high-calorie beverages such as sodas, beer, wine and juices.

Exercising or even visiting at altitudes above 8,200 feet can stimulate or increase urination and more rapid breathing, which can result in fluid loss. Illnesses with fever, vomiting, diarrhea, bladder infections or kidney stones also require increased fluid intake.

Older people do not need to drink more water. As we age, however, thirst becomes a less reliable indicator of need for fluid intake, and our bodies are less able to cope with heat and humidity. Therefore, seniors should drink fluids regularly, even before noticing thirst.

How much then should you drink? If you are healthy and not exercising or working hard, thirst is your best guide. Some experts recommend having a beverage with meals and drinking again when you are thirsty. In general, if you drink enough fluid so that you rarely feel thirsty and produce about 1 quarts or more of colorless or light yellow urine each day, you are probably taking in enough fluid. If you have health issues or sports-related concerns, you should check with your physician.

It is possible to take in too much water/fluid, and this can potentially cause problems, especially in those with kidney or other medical problems, or in endurance athletes.

And remember, just as with bottled water, don’t waste your money on “oxygenated water,” which claims to help your muscles, improve athletic performance and even “purify” your body. We have in the past and will continue to get oxygen into our blood by breathing — using our lungs, not our stomachs.
