Some years ago, a 28-year-old Californian wife and mother of three children died from drinking too much water. Her body was found in her home shortly after she took part in a water-drinking contest that was held by a local radio show. Called “Hold Your Wee For A Wii”， the contest organizers promised a free Wii video game machine to those who drank the most water without going to the bathroom. The woman who died drank about 2 gallons of water during the contest. When she and other participants complained of discomfort and showed signs of pains, they were laughed at by the organizers.
This tragic news story shows the importance of understanding why drinking too much water can be dangerous to your health. Consuming more water than you need can increase your total blood volume (容量)．And since your blood volume exists within a closed system, increasing your blood volume puts unnecessary stress on your heart and blood vessels (血管)．Your kidneys (肾) must work overtime to get rid of extra water out of your system.

Your kidneys are not a pair of pipes. Flushing more water through your kidneys doesn't necessarily help it become cleaner. Rather, your kidneys can get damaged by unnecessary wear and tear over time. And drowning your system with large amounts of water is one of many potential causes of kidney damage.
Putting unnecessary stress on your system and your kidneys by consuming unnecessary water is an unnoticeable process. For the average person, it is usually impossible to know that this stress exists, as there are usually no obvious symptoms on a moment-to-moment basis. But make no mistake about it: this stress is real and can hurt your health over the long term. 语篇解读：本文为说明文。过量饮水对我们的健康危害很大，我们应该避免过量饮水。
