Today is World Water Day, the elixir of our lives. Water is our lifeline, essential for survival. Unfortunately, water is now a scarce commodity and environmentalists are warning us of severe drought in the next few years.

Countries like South Africa, California in the US are facing severe short supply of water and many Indian cities and villages are no exception. We need water not only to quench thirst but also keep every cell, organ, tissue in the body activated and to maintain proper body temperature and other functions.

As the body loses water through sweating, breathing and digestion it is vital to rehydrate the body by drinking adequate fluids and having foods that contain water.

However, there are a whole lot of myths that are associated with water. Netmeds.com has compiled a factsheet on that separates fact from fiction.

Myth:

Myth:

Bottled Water Causes Tooth Decay

Myth:

You Don’t Need Much Water During Winter

Fact:

Summer is the time where people fuel them with a lot of water as they perspire more. As perspiring is a visible sign of dehydration in summer we keep drinking plenty of fluids, as in winter we don’t sweat a lot.
