Water

Our bodies can survive without some nutrients for months, but we can only live for 5-10 days without water! We’re mostly made of water too! We lose it when we sweat, when we breathe and in body waste.We use it to:

  • To carry nutrients and waste in the body
  • To lubricate joints, digestive tract and body tissues
  • To cool the body, especially during periods of physical activity.

 How much water do I need?

Most people need about 6-8 glasses of water each day. Caffeine-containing beverages (coffee, tea, colas, etc.) should not be included in this amount because caffeine acts as a diuretic and actually causes you to lose water.

More water may be needed during times of fever, illness, or high heat. Physically active people should drink additional amounts before, during and after exercise. A good rule of thumb is to add 1-3 cups per hour of physical activity. Thirst is not the best indicator of hydration. Often an athlete can be dehydrated and not feel thirsty. If you ignore your thirst, you may start to show signs of mild dehydration:

  •  Dry mouth
  • Less urine when you go to the bathroom
  • Dizziness or light-headedness

These are sure signs that you need to start hydrating quickly. Don’t let it get severe!

What happens when you don’t get enough water?

An adult loses up to 2-3 quarts of water per day normally. An athlete can lose up to 6 cups in just one hour of continuous activity. Inadequate fluid intake can lead to constipation and dehydration. Besides decreasing your endurance, dehydration can cause serious effects like heat stroke. Even a small amount of dehydration (1% of body weight or 1.5 pounds on a 150-pound person) can increase your risk of impaired performance and heat illness.

What about sports drinks?

Water is the best source of fluids for most athletes. It is readily absorbed and quickly replaces any lost fluids. For athletes exercising continuously for more than 60 minutes, a fluid with some extra nutrition may be beneficial. Diluted fruit juices, fruit drinks and sports drinks can effectively replace lost fluid as well as provide necessary energy to working muscles. Full-strength juices should be avoided during exercise as they may cause cramping or nausea. Sports drinks do have quite a few calories due to their relatively high sugar content. For recreational exercisers and those exercising less than 1 hour, the additional calories may not be necessary. Water would be a better and more refreshing choice.

What about bottled water?

It seems that everyone these days is drinking special bottled waters, spring waters, mineral water and even flavored water. It’s really a waste of money and energy. Regular tap water is carefully regulated to be safe to drink. Many bottled waters are simply tap water that has gone through some filtration process before bottling. Buy one or two good water bottles and keep them filled (Mother Earth will thank you).

If taste of your tap water is a problem, it could be the taste of the chlorine used to treat the water. Try filling a container with the tap water and keeping it in the refrigerator. The chlorine has a chance to dissipate before drinking. Or you can purchase a faucet water filtration system.
