The Effects of Dehydration
The effects of dehydration are numerous, and dehydration is more common than you might think.
The human body is anywhere from 55% to 78% water depending on age, gender and amount of body fat, and water
is essential to human life. Water forms the basis for all fluids in the body, such as blood and digestive juices,
and it's the catalyst in all metabolic functions throughout the body. Water removes toxins and waste products
from the body, and it carries nutrients to the cells of the body.
Your body is dynamic and always changing, and this is especially true with regard to water in your body. You
lose water routinely when your body performs normal functions such as breathing, sweating and eliminating waste.
In a typical day, you need to consume a substantial amount of water to replace this routine loss. Dehydration
occurs when the amount of water leaving your body is greater than the amount being taken in.
Severe dehydration can cause symptoms such as extreme thirst, lack of sweating, rapid heartbeat and delirium,
and it can be life-threatening. But most people who experience dehydration experience mild to moderate dehydration.
Here are the effects of dehydration at a mild to moderate level:
- Dry, sticky mouth
- Fatigue
- Muscle weakness
- Poor concentration
- Headaches
- Dizziness or lightheadedness
Many people who suffer from one or more of these ailments have no idea that dehydration is the cause, and
that getting relief is as simple as consuming more water.
So how much water should you drink to avoid dehydration? Eight glasses of water a day is a commonly quoted
amount, but this is just a general rule. The amount can vary widely from person to person depending on factors
such as age, physical condition, activity level and climate. If you drink enough water so that you rarely feel
thirsty (by the time you become thirsty, you might already be dehydrated) and you produce urine that's clear or
light yellow, your water intake is most likely adequate.
You also need to make sure that the water you drink is as clean as possible. This is why I recommend drinking
filtered water instead of tap water or bottled water.
Tap water contains trace amounts of a variety of contaminants, such as chlorine, lead, pesticides and herbicides.
Visit the Tap Water Facts page for more information on tap water. Bottled water
is often little more than tap water in a bottle. There are no government standards that require bottled water to be
any better, purer or safer than tap water. Visit the Bottled Water Facts page
for more information on bottled water.
Using a water filter is the only way to ensure that the water you drink is clean and contaminant-free.
In conclusion, mild to moderate dehydration affects many people and causes several common ailments. But dehydration
is easily preventable by consuming an adequate amount of clean, healthy water.
