Myth #1: 2 Quarts of water daily (64oz) is all adults need to stay hydrated.

Myth #2: Thirst is the best indicator of dehydration.
Taking a multivitamin may tine the color of your urine. Another method for monitoring hydration is to keep track of how often you visit the bathroom. Urinating at least every 2 hours is also a good sign that you are drinking enough water.
Myth #3: It is unhealthy to drink too much water
With the exception of certain health conditions, your body will only use the water it needs and will eliminate the rest.
Under normal conditions there is no risk associated with drinking too much water. It is recommended that water be sipped slowly instead of gulped down, which can cause gastric distress.
Myth #4: Drinking at lot of water is taxing to your kidneys
Water is required for good kidney function. When water intake is insufficient, the kidneys must compensate by excretion more concentrated urine, which may lead to the formation of kidney stones.

During winter sports activities, you won’t appear to be sweating as much. However, your body is still losing fluids and drinking water is a must or athletic performance will be affected.
