Water Lacey Ursu


Water is a colorless, and tasteless liquid. Water is essential for plants, animals and people. Men need roughly 13 cups of water a day while females only need 9.

Water - Essential Nutrient

Water is the single most important nutrient of life. Without water, no metabolic and physiological processes within the body can occur. Water is necessary for the movement of nutrients to the cells, removal of waste products from these cells, mineral or acid/base balance, protection of nervous system, lubrication of joints and body temperature control. Other signs of water being essential are that water is required in amounts larger than any other nutrient and represents approximately 50 to 80 % of body weight depending on age and fat content.

4 Main Functions of Water in the Body

Cell life- Water is essential for cells to function properly: it enters into the composition of the cells.

Chemical and metabolic reactions- By enabling hydrolysis reactions, water participates in the biochemical breakdown of what we eat (proteins, lipids and carbohydrates). This is one of many reactions in which water is involved.

Transport of nutrients and removal of waste- Water as a main constituant of blood contributes to the transport of nutrients to the cells. In deed the nutrients are transported by the blood. Water, as a carrier, also helps removing waste products through urines.

Body temperature regulation- Water has a large heat capacity which helps limit changes in body temperature in a warm or a cold environment. Water enables the body to release heat when ambient temperature is higher than body temperature (2): we begin to sweat, and the evaporation of water from the skin surface cools the body very efficiently.

Source of the Body's Water Supply

We can get about 20 percent of the water we need through the food we eat.

Bottled Water vs Tap Water

The choice of tap or bottled is mostly a matter of personal preference. The Food and Drug Administration (FDA) oversees bottled water, while the Environmental Protection Agency (EPA) regulates tap water. However, they use similar standards for ensuring safety.

Drinking to Much Water & Effects

Drinking excessive amounts of water is linked to many extreme sweating problems and some so severe they are considering surgery to remove their sweat glands. Drinking large amounts of water, particularly at the end of the day, can disrupt sleep, too. You can die of water poisoning. To much water can also lead to irritability, headaches, confusion and restlessness.
