H2 Oh...the importance of hydration

As I am listening to the Microbiome Medicine Summit today, I am reminded of the importance of pure water. I wrote a previous blog post about digestion, which mentions how pure water helps rid the body of waste; however, water does so much more than that. ​

What does water do for my body?

Water is a nutrient essential to life. It is the primary component of all bodily fluids - blood, lymph, digestive juices, urine, tears, and sweat - and is involved in almost every bodily function. Water makes up 60% of our total body weight and is second in importance only to air for sustaining life. It is impossible to live for more than a week without it. 

Some uses of water

​Regulates the body’s temperature 
Cushions and protects vital organs 
Lubricates and cushion the joints 
Aids the digestive system 
Helps with weight loss 
Acts within each cell to transport nutrients and dispel waste 
Gets rid of wastes through urination, perspiration, and evacuation

Must I get all of my fluids from water?

You can become hydrated in a number of ways, but water is the best fluid replenisher for most individuals. Other beverages that may be hydrating are herbal teas, juices, smoothies, coffee, soda or energy/sports drinks. Some view these beverages as fine substitutes because they contain water, but beware. Coffee is a diuretic and in excess can cause us to excrete more water than it contains. Soda, juices, and energy/sports drinks contain much sugar, which upsets water balance. Also, sugar sweetened beverages provide empty, unneeded calories. In addition to drinking water, you can get hydration from fruits and vegetables like watermelon, cucumber, tomato, lettuce, and celery. ​

Should I drink only when thirsty?

​Thirst is not fully reliable. Thirst is a signal that your body is already on its way to dehydration. It is important to drink more than thirst demands and continue to drink throughout the day.

Dehydration

Without enough water, we literally dry ourselves out. Dehydration is linked to chronic health problems like arthritis, diabetes, colitis, high blood pressure, kidney stones, and multiple sclerosis.

Dehydration symptoms

    

​        Dark urine / constipation
        Dry skin / dry mouth
        Extreme thirst
        Dizziness / fatigue

How much do we really need?

Water requirements vary greatly from person to person and depend on the climate in which we live, our activity level, and our diet. However, a water goal would be to divide your body weight (in pounds) by 2. Aim to drink that many ounces of water daily. If you weigh 160 pounds/2 = 80 = ounces of water needed daily. Add an additional 8 ounces for every half-hour of exercise.

Tips for reaching daily water goals

• Drink an 8 ounce glass or two of water upon waking in the morning (literally gets things moving).
• Drink an 8 ounce glass about 30 minutes before each meal (this helps satiate you; the sensation of thirst is often confused with hunger).
• Drink an 8 ounce glass before bedtime.
• Or drink a glass of water at the top of each hour for easier tracking. Include extra glasses of water if you exercise, live in a warm climate, have fever, diarrhea, vomiting, or certain medical conditions. 

Don’t like the taste of plain water?

Infuse your water with flavors, like cucumbers, strawberries, lemons, or fresh herbs. A water pitcher infused with fruit is great to have on hand. ​
