The body does not store water the way it stores food and energy. A person can survive for a few weeks without food, but will only live a few days without water. Water has no calories, vitamins or minerals, but it is essential to life. The temperature of drinking water depends on individual taste.
When the body's water level drops too low, a person may become dehydrated, become lightheaded and/or experience a rapid heartbeat. Water requirements vary from person to person, and depend a lot on activity levels. Thirst is not always a good indicator.
Water can help with weight loss, it keeps joints well-lubricated, it eliminates waste from the body, it prevents the skin from drying out and it regulates circulation.
Most of the water consumed comes from liquids. However, a lot of foods contain water. Fruits and vegetables contain a great deal of water; a hamburger is 50 percent water; and Swiss cheese's water content is 38 percent.
Clean spring water or filtered water is recommended by many experts. Some warn against tap water, fluoridated or distilled water due to bacteria, metal content or other contaminants.
An article published on July 20, 2009, in The New York Times suggested that people should not worry too much about the temperature of their drinking water and be more concerned with consuming enough.The study by the American College of Sports Medicine (ACSM) found that the biggest factor in drinking enough water is simply taste.
Cold Water Myth
The New York Times article cited a 2006 study published in The Journal of Clinical Endocrinology and Metabolism that found that cold water does not have an impact on increasing calorie burn. Also noted was that water should be kept between 59 and 72 degrees Fahrenheit, but this was again due to the taste factor.
